This adult female has not quite finished her meal here. Once a spider has caught its prey and will want to eat its food the first step is to literally vomit a digestive fluid all over the food and then to chew the item with the jaws (chelicerae), then on to suck up the fluid back into the mouth together with the liquified meat. Some spiders can produce at least six different kinds of silk and if spiders were scaled to the same size as us it is said that the Web would be strong enough to catch a helicopter. It has also been claimed that a cable of silk as thick as a thumb woven from spider silk would be able to bear the weight of a jumbo jet.
This spider is usually found low down in vegetation in a funnel web often in brambles, gorse and heather, In late summer the female will construct a chamber within the web which is made up of a complex maze of silken tubes that will contain her egg sac and will often be seen guarding the entrance. The spiders main primary function is to quickly immobilize and subdue its prey and start the digesting process. The venom can contain many different substances which can include amino acids, proteolytic enzymes and neurotoxic polypeptides.

Unfortunately most of us have been brought up in life from young children to fear a spider and most will feel sorry for the bee straight away but how many feel sorry for the bee in a beak of a stunning looking Bee-Eater Bird or the Stickleback fish repeatably being hit on a branch before being swallowed down whole by a stunning blue King Fisher or even a earth worm that snaps in half when being pulled out of the ground by our friendly Robbin in our gardens. The answer is not many as all three do not have eight legs and look like a spider, its a funny old world that we live in.
The red dog bin in my local park came in very handy for this one. The spider's main primary function is to quickly immobilize and subdue its prey and start the digesting process.

A few years ago there was a article about this dog who could balance things on it's head. The main picture was it balancing Digestive biscuits. I think it had a stack of 12. I just said to myself I bet Asha could beat that as she has always balanced things on her head since a little pup. So out came the Digestives. I managed 14. I'm sure I could even have beat that target but I ran out of Digestive biscuits (only had the one pack minus some I ate..lol). As you can see Asha had a few wee mishaps with them...lol. I must get another packet of Digestive Biscuits and try and beat 14...Watch this space!
No escape. I watched as Lucilia's right wing got caught on the sticky 'tentacles' of this Fork-leaved Sundew. A bit of a struggle, but that only brought it into contact with more of those glue-droplets. They're composed of a sugary mucilage apparently attractive to Lucilia. When those tentacles sense a prey is 'stuck' they begin to also secrete a digestive fluid: some enzymes among which a chitinase which dissolves the chitin outer protection of Fly. At the same time the stalk-leaf of Drosera is stimulated to bend a bit to bring as many of those tentacles as possible into contact with Food. The dissolving Fly is then slow absorbed into Sundew through those same tentacles, through the plant's outer cells, and through so-called sessile glands on its surface (the latter are small and unfocused in the photo but you can make them out in particular on the left between the tentacles). The dark spots top right and bottom left are what'll be left of Lucilia, too, once the longish lunch is over.
Here's a Sundew from North America. It has long and slender, erect 'tendrils', filaments covered with tiny hairs or trichomes with globules of sticky exudate at their ends. They serve to trap small insects and also contain digestive enzymes that soon reduce insects to plant nutrients. Then it'll have energy to produce these pretty pink flowers.
Our 'elegant species', as writes Frederick Traugott Pursh (1774-1820), was seen by him near Tuckerton, New Jersey, about 1805. He describes it 1813/1814, too late for Constantine Samuel Raffinesque (1783-1840) to have read it. Usually Raffinesque quotes Pursh if the latter saw a specific plant before he did, but he saw this Drosera around 1803/1804 also in New Jersey and described it in 1808, well before Pursh. Hence its find is attributed to him.
African Elephant digestive systems are quite inefficient; they only digest about 25% of what they eat. Dung beetles feed on feces, recycling the nutrients and are quite important to the ecosystem.
this was taken during my last digestive disease convention at the washington dc convention center. the bags during this particular convention had always been purple all these years! lol! pretty funky eh? aside from the bags, i found this particular shot quite interesting, the delegates sitting on the stairs in different animated poses! what were they doing out of the conference room anyway? lol! and what was i doing taking pictures and not attending the lectures???
-----------------------------------------------------------------------------------------------------------------
i posted this shot first in ipernity, and now that i just decided to delete my account there, it will be posted here. i love the site, i think there are a lot of features that definitely make it worth going to, but flickr is my home and it becomes just too difficult and time consuming for an old man like me to toggle between two photo sites in one day! so my friends from the other side, forgive me, but i will just stay here.

MALACHI: “Look what I found, Mutzli!”
MUTZLI: “What is it, Malachi?”
MALACHI: “It’s a delicious chocolate coated McVities Digestive Biscuit!”
MUTZLI: “My goodness Malachi! It’s huge!”
MALACHI: “I know! It’s the perfect size for two little bears with grumbly tummies to enjoy for elevenses, Mutzli.”
MUTZLI: “But where did it come from, Malachi? It can’t have appeared on its own on this pretty plate.”
MALACHI: “That’s true Mutzli. I think Daddy left it on this plate.”
MUTZLI: “Then mightn’t this McVities Chocolate Digestive Biscuit be for Daddy, for his elevenses, Malachi?”
MALACHI: “You can be so dense sometimes, Mutzli. I should have thought it was obvious. Daddy isn’t here, so he must have left it for us to find and enjoy.”
MUTZLI: “Are you sure he just hasn’t left it here whilst he goes to make a cup of tea?”
MALACHI: “Daddy would be very silly to leave a McVites Chocolate Digestive unattended when there are bears with grumbly tummies around, Mutzli. No! It must be for us.”
MUTZLI: “Alright Malachi.” *Ponders.* “Are you quite sure Daddy won’t mind us eating this sweet biscuit?”
MALACHI: “Of course he won’t Mutzli! Daddy has a whole packet of McVites Chocolate Digestive Biscuits in the pantry if he so desires. He can get his own. Besides, don’t you have a grumbly tummy?”
MUTZLI: “Oh I do, Malachi! Grumbly tummy, Malachi. Grumbly tummy.” *Rubs tummy vigorously.*
MALACHI: “That settles it then! Let’s enjoy our elevenses.”
DADDY: “Ummm… Malachi?”
MALACHI: “Oh!” *Looks up and sees Daddy watching he and Mutzli. “Yes Daddy?”
DADDY: “Malachi, pardon me for asking this, but what exactly are you and Mutzli doing?”
MALACHI: “Well, I thought that was obvious Daddy! We are helping ourselves to some elevenses that you kindly left us. Grumbly tummy Daddy! Grumbly tummy!” *Rubs tummy vigorously.*
DADDY: “Well that's all well and good Malachi, but how am I meant to have my elevenses if you and Mutzli are eating it?”
MALACHI: “Well, I'm not entirely sure Daddy, but I'm sure you will think of something.” *Smiles and takes bite from of McVites Chocolate Digestive Biscuit.*
MUTZLI: “Hullo Daddy!” *Blushes pink beneath plush white fur.* “Grumbly tummy?”
The theme for "Looking Close on Friday" for the 14th of July is "sweet food in a square photo". I must confess that the older I get, the less of a sweet tooth I have, but I am still partial to the occasional McVities Dark Chocolate Digestive Biscuit with a cup of tea. I immediately thought of photographing one in the centre of one of my 1920s Art Deco Square plates (in this case a Royal Albert one featuring an unnamed pattern). However, I thought I would add a little bit of humour and interest to my submission for the theme this week by using Malachi and Mutzli again after their reappearance at "Looking Close on Friday" after a long hiatus for the themes "capture the time", "eraser" and "a single marble".
If you follow my photostream, you may know that I collect 1:12 size miniatures, some of which have featured in past themes in the "Looking Close on Friday" and "Smile on Saturday" groups. This includes Malachi the bear, who today is joined by his cousin, Mutzli and the pair are enjoying a larger than life elevenses treat of a sweet biscuit. I do hope that you like my choice, and that this photograph makes you smile!
Malachi I acquired in mid-March 2020 (and mid Coronavirus) from a wonderful Melbourne stalwart toy shop: Dafel Dolls and Bears, when I went looking for a present for one of my goddaughters. Malachi is designed by Mary and hand-made by Wendy Joy in Australia. He has articulated arms and legs, and an extremely sweet face. Malachi was the name he came with, written by hand on his little tag.
Mutzli was a lovely surprise gift from a dear friend in Britain who kindly slipped him into a parcel of other delightful gifts for me. Like Malachi, he is mohair, has articulated arms and legs, and an extremely sweet face. Mutzli got his name from the tiny gold tag around his neck. He is made by Mutzli, a Swiss bear manufacturer since 1949.
fungus (plural: fungi or funguses is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista.
A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the Eumycota (true fungi or Eumycetes), that share a common ancestor (i.e. they form a monophyletic group), an interpretation that is also strongly supported by molecular phylogenetics. This fungal group is distinct from the structurally similar myxomycetes (slime molds) and oomycetes (water molds). The discipline of biology devoted to the study of fungi is known as mycology (from the Greek μύκης mykes, mushroom). In the past, mycology was regarded as a branch of botany, although it is now known fungi are genetically more closely related to animals than to plants.
Abundant worldwide, most fungi are inconspicuous because of the small size of their structures, and their cryptic lifestyles in soil or on dead matter. Fungi include symbionts of plants, animals, or other fungi and also parasites. They may become noticeable when fruiting, either as mushrooms or as molds. Fungi perform an essential role in the decomposition of organic matter and have fundamental roles in nutrient cycling and exchange in the environment. They have long been used as a direct source of human food, in the form of mushrooms and truffles; as a leavening agent for bread; and in the fermentation of various food products, such as wine, beer, and soy sauce. Since the 1940s, fungi have been used for the production of antibiotics, and, more recently, various enzymes produced by fungi are used industrially and in detergents. Fungi are also used as biological pesticides to control weeds, plant diseases and insect pests. Many species produce bioactive compounds called mycotoxins, such as alkaloids and polyketides, that are toxic to animals including humans. The fruiting structures of a few species contain psychotropic compounds and are consumed recreationally or in traditional spiritual ceremonies. Fungi can break down manufactured materials and buildings, and become significant pathogens of humans and other animals. Losses of crops due to fungal diseases (e.g., rice blast disease) or food spoilage can have a large impact on human food supplies and local economies.
The fungus kingdom encompasses an enormous diversity of taxa with varied ecologies, life cycle strategies, and morphologies ranging from unicellular aquatic chytrids to large mushrooms. However, little is known of the true biodiversity of Kingdom Fungi, which has been estimated at 2.2 million to 3.8 million species.[5] Of these, only about 148,000 have been described,[6] with over 8,000 species known to be detrimental to plants and at least 300 that can be pathogenic to humans.[7] Ever since the pioneering 18th and 19th century taxonomical works of Carl Linnaeus, Christiaan Hendrik Persoon, and Elias Magnus Fries, fungi have been classified according to their morphology (e.g., characteristics such as spore color or microscopic features) or physiology. Advances in molecular genetics have opened the way for DNA analysis to be incorporated into taxonomy, which has sometimes challenged the historical groupings based on morphology and other traits. Phylogenetic studies published in the first decade of the 21st century have helped reshape the classification within Kingdom Fungi, which is divided into one subkingdom, seven phyla, and ten subphyla.
On a delicate stem about 15 cm above its rosette of leaves almost flat on the ground sways this pretty pink-purple flower of Pinguicula macroceras, Horned Butterworth. Its nectar lines morphing from purple-pink to white lead insects such as Bees to the nectar produced in the 'large horn' - macroceras - which you can just see peeping out from behind the top two petals. Other pollinators, too, are attracted to this sweetness. In order to be effective at their job, they, of course, need to be able to leave Flower. So Flower keeps its stemmed distance from its own leaves (see upper right inset for that rosette).
Those succulent or fatty - Pinguicula - leaves are covered with tiny stalked cells which secrete a sweet, sticky mucilage that attracts other, smaller insects for Plant's meal. These insects - obviously not pollinators - struggle against that stickiness, but to no avail. The more they struggle, the more mucilage is secreted and before long they're totally stuck. In the inset, bottom right, Olymp could just see some of those stalked, sticky-topped stems that had caught themselves a small insect. The unclear brownish blotches on leaf's surface are the so-called sessile glands that now begin to secrete a range of digestive enzymes. And soon Insect'll have been consumed. Then Pinguicula will have energy to produce its flower which will yield seed... And so on...

Not just Digestive biscuits either. In an evening after Graham has gone to bed and I'm still watching the TV, I raid the biscuit tin and happily munch my way through 2 of whatever we have in.
Chocolate chip ones are the most difficult to resist and to only have 2 is even harder.
Graham has now discovered my secret - drat!
Thank you for your favourites. :O)
I do enjoy a chocolate digestive biscuit but I'll put these away for later!!

Thanks to everyone who views this photo, adds a note, leaves a comment and of course BIG thanks to anyone who chooses to favourite my photo .... Thanks to you all!
From the days when they put biscuits in bottles ... (actually the full wording on the bottle is "Watkins's Digestive Relish".
Previously posted in an uncropped, more luridly coloured version.
Actually blue Stilton and digestives but the strongest flavour comes from the bacteria so let’s be honest about what we’re eating.
This is my contribution to Macro Mondays theme of "Perfect Match". It is a Hovis digestive biscuit with a piece of Belton Farm Sage Derby cheese. The biscuit is sweet and is complemented by the smooth, creamy Derby cheese marbled with a delicate sage infusion - I would usually have a glass of port too to accompany this perfect match - HMM

These Hypricum Berries are commonly used in floral displays but they are toxic and must never be eaten as it will cause digestive problems, also skin irritation and rashes if the consumer is exposed to sunlight. The flowers are star shaped golden yellow and they grow in clusters on the plant and the leaves have a woody fragrance. Its quite amazing how something that looks lovely can have the opposite effect on people.
Traditionally, Tansy, Tanacetum vulgare, was used to treat digestive disorders. Thinking about this, I wondered how Hoverflies digest those small but quite hard and tough pollen particles. It used to be thought that Our Flies were able to crush the pollen by sheer physical force. That idea has been discarded. Today research has led to the insight that the enzyme action of nectar sugar in the Fly's Stomach opens the pores of the outer skin of pollen grains so that their nutrients can be accessed. Highly fascinating...
This is Myathropa florea, Flower Hoverfly or Deathhead Fly. The name Myathropa was devised by the Italian entomologist Camillo Róndani (1808-1879), but he was clearly a bit sloppy in his Greek derivation. If he'd been precise, he would have written 'Myiatropa' - deriving from the Greek words for fly and for personified death or destiny (=Atropos). This was pointed out by George Henry Verrall (1848-1911) in 1901. But to no avail because the scientific name had already been officially established. So word purists will have to grit their teeth when it is said that 'Myathropa', from the Greek, means 'Deathhead Fly'. The 'blot' of a Deathhead or Skull can vaguely been seen on our Hoverfly's thorax.

When an Insect - Spiders, too - triggers those tiny red hairs on the inner lobes of a Venus Flytrap (see inset), the Trap snaps shut capturing a tasty morsel. It'll struggle a bit but inexorably our Insect will be caught up in a tightening, barred cell. There are just enough of those triggers to ensure that it's really an insect that's alighted on that lobe and not some little piece of detritus.
Our Caught Spider was unwisely spinning her web on Venus's 'teeth'; you can see part of it on the left. Somehow Ariadne must have lost her own thread and venturing 'south' triggered those hairs. Prisoner! and soon to be dissolved for a meal by Venus's enzymatic secretions. So far so bad for her; so far so good for Venus...
Or is it really good for Lady Trap? In this case: nope. Her Trigger Hairs felt bigger than her stomach. Ariadne is rather too big for her; body parts are sticking out from Venus's prison. Those spider legs can't be covered in 'antiseptic' digestive fluid. They're open to the air and to the manifold fungi and bacteria that dispose of dead insects. Soon those body parts will turn black, and in turn they'll infect pretty Green Trap, turning her Black to Death as well. Retribution for gluttony?...
In the chilly drizzle I was pottering about a bit around the Océ Pond where stands the pretty, almost blossoming Farrer's Wayfaring Tree (www.flickr.com/photos/87453322@N00/6812458018/in/photolis...). Beneath it was a moss-covered tree trunk. I thought it might be interesting to look under the bark so I carefully lifted a small section away. Letting in the gloomy daylight I saw a 'hibernation' of a hundred or so Black Snail Beetles. Heads withdrawn under pronota, they await warmer weather. When they've become active again, they hide away similarly during the day and hunt at night. They'll find earthworms and snails and such. Grasping soft mucuous parts, the Beetle bites and injects a yellowish digestive fluid that will dissolve mucus and then its prey's innards preparing it for a liquid meal. In the photo the blacks are the mature adults, the reddish the younger ones.
Yes, I did carefully replace that segment of mossy bark perhaps to the dismay of also hibernating prey.
