The old apparently degrated reef right on the inshore is common in far North Queensland. I don't think it ever ewas proper reef, only aggregations of coral substances. It is hard when you walk on it with lots of holes and clefs and pools that do contain small fish and crabs and other sea life. There is seaweed and algae growing there too.
The farmers in North Queensland are getting blamed by the Premier of Queensland who introduced awful legislation against farmers last week, blamed for the destruction of the Reef. This is garbage. The Barrier Reef is as healthy as ever - it is a greeny fallacy and the Government is bending over backwards to the greenies because they want the votes in the next election and people in the south don't know the real truth here and believe all this stuff. It is so sad. I know that every year the rivers run dirty orange and brown with lots of sediment BUT the rivers have always done this. Most of that sediment comes from unpopulated and undeveloped areas in the inland and even in untouched rainforest 10 inches of rain in a day scours the soil out that runs muddy out to the rivers. Mangroves in mud flats have always been at the forefront of beach expansion into the sea. Here in Cairns some 5 and 6 km in from the beach, under the top layer it is all sand and then mud proving that for a couple of thousand years mud has been carried by rivers.
We ought to be told the truth. Farmers don't use much fertiliser because it is so expensive and it is scientifically monitored when it is aplied. To blame them is nothing but political expediency by a government which releases 3 metre dangerous crocodiles in populated areas that ruins businesses as has happened around Magnetic Island this week.
I came across a mating aggregation of Chromis viridis, where an estimated few thousand individuals crowded on a patch of seagrass in ~ 5 meters and frantically mated. The males turned either slightly yellow, with black fin edges, or completely yellow, with a black caudal fin. What a spectacle!

Mud-puddling is the phenomenon mostly seen in butterflies and involves their aggregation on substrates like wet soil, dung and carrion to obtain nutrients such as salts and amino acids. This behaviour has also been seen in some other insects, notably the leafhoppers.
Lepidoptera (butterflies and moths) are diverse in their strategies to gather liquid nutrients. Typically, mud-puddling behavior takes place on wet soil. But even sweat on human skin may be attractive to butterflies.The most unusual sources include blood and tears.
This behaviour is restricted to males in many species, and in some like Battus philenor the presence of an assembly of butterflies on the ground acts as a stimulus to join the presumptive mud-puddling flock.
In tropical India this phenomenon is mostly seen in the post-monsoon season. The groups can include several species often including members of the Papilionidae and Pieridae.
Males seem to benefit from the sodium uptake through mud-puddling behaviour with an increase in reproductive success. The collected sodium and amino acids are often transferred to the female with the spermatophore during mating as a nuptial gift. This nutrition also enhances the survival rate of the eggs.
When puddling many butterflies and moths pump fluid through the digestive tract and release fluid from their anus. In some, such as the male notodontid Gluphisia septentrionis, this is released in forced anal jets at 3 second intervals. Fluid of up to 600 times the body mass may pass through and males have a much longer ileum (anterior hindgut) than non-puddling females
When we looked more closely we started to see even larger aggregations, mostly clinging to "oyamel" (Abies religiosa). | Cerro Pelón, Mexico, Mexico | December 31, 2016.

Blue Wildebeest
The blue wildebeest (Connochaetes taurinus), also called the common wildebeest, white-bearded wildebeest, or brindled gnu, is a large antelope and one of the two species of wildebeests. It is placed in the genus Connochaetes and family Bovidae, and has a close taxonomic relationship with the black wildebeest. The blue wildebeest is known to have five subspecies. This broad-shouldered antelope has a muscular, front-heavy appearance, with a distinctive, robust muzzle. Young blue wildebeest are born tawny brown, and begin to take on their adult colouration at the age of 2 months. The adults' hues range from a deep slate or bluish gray to light gray or even grayish brown. Both sexes possess a pair of large curved horns.
The blue wildebeest is a herbivore, feeding primarily on short grasses. It forms herds which move about in loose aggregations, the animals being fast runners and extremely wary. The mating season begins at the end of the rainy season and a single calf is usually born after a gestational period of about 8.5 months. The calf remains with its mother for 8 months, after which it joins a juvenile herd. Blue wildebeest are found in short-grass plains bordering bush-covered acacia savannas in southern and eastern Africa, thriving in areas that are neither too wet nor too arid. Three African populations of blue wildebeest take part in a long-distance migration, timed to coincide with the annual pattern of rainfall and grass growth on the volcanic soil short-grass plains where they can find the nutrient-rich forage necessary for lactation and calf growth

Gnu-de-cauda-preta
O gnu-de-cauda-preta (Connochaetes taurinus) ou boi-cavalo-de-cauda-preta [2] (em inglês, blue wildebeest, "gnu-azul") é uma das duas espécies de gnu, encontrada no Leste e Sul da África e contando com pelagem cinzenta, mas face e a cauda negras.
O gnu é um herbívoro que se alimenta principalmente de gramíneas curtas. Estes animais são corredores rápidos e extremamente cautelosos. A estação de acasalamento começa no final da estação chuvosa e um único filhote geralmente nasce após um período gestacional de cerca de 8,5 meses. O bezerro permanece com sua mãe por 8 meses, após o qual se junta a um rebanho juvenil. Os gnus são encontrados nas planícies de grama curta que margeiam savanas de acácia cobertas de arbustos no sul e no leste da África, prosperando em áreas que não são nem muito úmidas nem muito áridas. Três populações africanas de gnus participam de uma migração de longa distância, programada para coincidir com o padrão anual de chuva e crescimento de grama nas planícies de grama curta do solo vulcânico, onde podem encontrar a forragem rica em nutrientes necessária para a lactação e crescimento de bezerros

A farmer holds cow peas at Mukothima Grain Aggregation Centre in Tharaka North Sub County, Kenya on 19th July 2016. With help from AGRA, farmers in the area have formed organisations to help them get better prices for their harvest by selling in bulk. Farmers deliver their grain to aggregation centres like this one in Mukothima from where they sell their grain.

Unfortunately I only had a 60mm macro on when I found this aggregation and the viz was around 2-3 metres.

Here's another view of the small aggregation of Andrena barbilabris (Hym. Andrenidae) I have found in the city of Bruxelles (Belgium). This pavement is made with old stones where a 2cm sandy space separates every stone. This is precisely what the bees look for here, and they have managed to settle there (virtually) undisturbed. The local robins seem to find it interesting too, I have observed them picking the female bees as they emerged to eat them!

These images, which include an encounter with a huge whaleshark were taken far offshore off Costa Rica close to an illegal fishing device (FAD). This Fish Aggregation Device was a raftlike structure manufactured to attract as much sealife as possible, but mainly spawning tuna.
Purse sein fisheries scoop up all life that has accumulated around the raft with their massive nets. Any bycatch from small fish to this huge whaleshark, dolphins and even seaturtles are killed in the process. That is why these FAD's are illegal.
They are however used widely in the pacific to feed our tuna riddled dishes..
A Greenpeace activist holds a banner under a fish aggregation device (FAD) calling for "Marine Reserves Now". Around 10% of the catch generated by purse seine FAD fisheries is unwanted bycatch and includes endangered species of sharks and turtles. The catch of large amounts of juvenile bigeye and yellowfin tunas in these fisheries is now threatening the survival of these commercially valuable species. Greenpeace is calling for a total ban on the use of fish aggregation devices in purse seining and the establishment of a global network of marine reserves.
I made this trip to see the spawning aggregations of Goliath Groupers. The week before I arrived there were torrential rains and strong winds from the southwest which had blown the Gulf Stream far offshore. The water was stirred up, green, full of floc, and with a thermocline around 40-55’. But the Goliaths were still there and really impressive!! Frequently 15-30 or more per wreck; it was hard to count with the limited vis. I will be planning to come back next year hoping for better picture taking conditions.
This building, probably the aggregation of three smaller buildings, derives its name from the discovery of human remains in a second floor room in 1831. This was the first body to be found in the town which had assumed to have been abandoned when the eruption began.

This aggregation of large ascidians is the genus Herdmania. There is one in the middle with a different syphon; white with a red rim. I suspect this is H. grandis whilst the others are H. momus?

Description
Hilton Ruiz, whose life ended in tragic circumstances in New Orleans in 2006 was a hugely talented and popular artist. From his solo work to the now legendary duets with the late Major Holley, Rahsaan Roland Kirk, Tito Puente, Symphony orchestras, and the various aggregations of his own, Hilton was a master of many styles. When it came to caressing the ivories, Ruiz had the class of Erroll Garner and Noro Morales with the sophistication of Duke Ellington and Ernesto Lecuona all wrapped up into one. You'll hear these elements and more when listening to this album including the explosive rhythm section of Andy Gonzalez on bass, Steve Berrios on drums, Giovanni Hidalgo on congas and percussion, and tenor saxophonists David Sanchez and Peter Brainin.

This bit of north London is around the southernmost limit of the last glaciation, and as a result soil types can vary over quite small scales. Here the soil is rather sandy and friable, whereas in my garden (just a few minutes walk away) it's heavy London clay.
This bank is also very open and faces south, giving it a warm and sheltered aspect, and making it ideal for soil nesting invertebrates such as solitary bees. In particular, a large aggregation of the Grey Mining Bee (Andrena cineraria) uses this area.
