Sand bubbler crabs live in burrows in the sand, where they remain during high tide. When the tide is out, they emerge on to the surface of the sand, and scour the sand for food, forming it into pellets, which cover the sand in amazing patterns. As the tide rises it disintegrates the pellets and they start again the next day with a blank canvas creating another beautiful sand pellet painting!
I have always thought that these were Sand Bubbler Crabs, but Google Lens is now telling me that they are Horned Ghost Crabs. Either way they are great fun to photograph and while away an afternoon on the beach.
After weeks of confinement I thought it was time to download what was in the camera and surprise ..... more crabs, A sand bubbler crab showing its all terrain abilty on Chinamans Beach, Evans Head.
Heading back to Evans Head tomorrow and hoping to get a few more shots of these guys. Sand bubbler crab on Chinamans Beach.
I dusted off the camera and the long lens and headed down the beach and found this guy going about his business. Cute in a funny sort of way.
Fascinated by the patterns of the little sand balls and traces left by tiny bubbler crabs, astonishing artists of the beach. The sandy brown colouration has them well camouflaged on the sand and when they have the least sense of a threat they are quick to disappear in the little holes which are their burrows.
The Sand Bubbler Crabs feed by filtering sand through their mouth parts, eating the micro-organisms and detritus that they find in there. They discard the sand in the form of little balls, probably to prevent sieving through the same sand twice, and kick it aside. They tend to start foraging close to their burrow and spiral out as they cover their territory. Moving around in this spiralling way causes them to create these beautiful patterns on the beach.

Sand bubbler crabs filter the wet sand for food, and along the way roll it into a neat ball. This shot is of a young crab next to one of the balls, around 3 mm across. The magnified sand grains look a bit like rice. Broken Head

Sand bubbler crabs (or sand-bubblers) are small crabs - around 1cm (0.4 in) across the carapace - that live on sandy beaches in the tropical Indo-Pacific. They feed by filtering sand through their mouthparts, leaving behind balls of sand that are disintegrated by the incoming high tide. Sand bubbler crabs live in burrows in the sand, where they remain during high tide. When the tide is out, they emerge on to the surface of the sand, and pass the sand through their mouthparts, eating detritus and plankton, and discarding the processed sand as pellets, which cover the beach. The crabs work radially from the entrance to their burrows, which they re-enter as the tide rises and disintegrates the pellets. In each burrow, the crab waits out the high tide in a bubble of air.
Torquay Beach, Hervey Bay QLD. The main sand patters are created by Sand Bubbler Crabs which small crabs that live on sandy beaches in the tropical Indo-Pacific. They feed by filtering sand through their mouthparts, leaving behind balls of sand that are broken up by the incoming high tide.

Sand bubbler crabs live in burrows in the sand, where they remain during high tide. When the tide is out, they emerge on to the surface of the sand, and scour the sand for food, forming it into inflated pellets, which cover the sand. The crabs work radially from the entrance to their burrow, which they re-enter as the tide rises and disintegrates the pellets. The material consumed by [the crabs] has a very low concentration of organic matter, which is concentrated by egestion of indigestible material. thekidshouldseethis.com/post/sand-bubbler-crabs

Don't you hate it that at the end of your holiday on the very last day, this is offered to you.... it makes it hard to leave. :) This morning most of the heavy morning cloud, that had been around for most morning of our stay had cleared and I was privy to the most glorious of sunrise on Four mile Beach..Just me, another lady taking photos and the Bubbler Crabs lol ;)
This shot is pretty much straight off the camera, I did adjust the horizon level a little as it was dark when I got there and I tilted left not right and the silly horizon did not tilt with me ...don't you hate that.
The sunrise when I was down on the sand started as a pretty pale pink colour and then continued to grow deeper and richer when I walked around the point to this view before dying out.
This lone palm sits on the rocky hill at one end of the Four Mile Beach. It made for a bit of interest in the shot.
So well worth the 5:15am alarm, don't you think ;)
Home again now ............

Scopimera inflate - Is the Bubbler crab. They dig through sand and absorb the nutrients before expelling these little balls in patterns around their burrows. This is Cable Beach, Broome. Western Australia.

Four-Mile Beach, Port Douglas, Queensland, Australia
Sand Bubbler Crabs are tiny being about 1cm long. They feed by filtering sand though their mouthparts, this leaves behind tiny balls which they then deposit around their burrows.
The amazing thing is when you look along the beach you can see their work stretching along the tide-line as far as the eye can see.
Darwin, Australia
According to Chris Riley "Each grain of sand has a thin coating of nutrients, food for these little critters. They wait out the tide in a little air picket inside their hidey hole, and as soon as tide recedes, out they come. They can be seen busily sifting through the damp sand for hours, rolling the discarded sand into balls and laying it out on the sand to ensure they don’t sift the same sand twice. The longer the tide is out, the more balls they create. Seemingly the pretty patterns are mere coincidence." lifeofrileyow.com/2021/08/21/the-sand-bubbler-crab-a-mast...
While the designs may be a "mere coincidence" I believe that there might be a deeper artistic sense at work. I found the designs truly inspired!!

Here's the smallest crab I found on this year's trip to Thailand. Thanks to Mr. Jacobi, I now know it to be some sort of sand bubbler crab (Dotilla sp.). The sand which it so neatly has rolled into balls like that is actually very fine, but compared to my little friend here it looks quite coarse.
The whole of Four Mile Beach at Port Douglas is covered in little balls of sand made by these Sand Bubbler Crabs. I spent a little time with the macro lens down the beach today catching the little critters. Most of these are just a little bigger than your finger nail.
Sand bubbler crabs (or sand-bubblers) are nocturnal crabs of the genus Scopimera. When low tide exposes a beach, these crabs emerge from their burrows beneath the sand. They begin feeding by collecting sand and quickly sifting it in search of microscopic food (detritus) between each grain, inadvertently cleaning the sand. When the sand is stripped of any nutrition, the crab gathers it into a sphere and tosses it behind their legs.
After feeding, Australian sand bubbler crabs appear to become lethargic and can be found resting on the exposed sand.[citation needed] It is during this time that the crabs are particularly vulnerable to predation. If threatened, sand bubbler crabs remain immobile and do not retreat beneath the sand to safety. This is unusual behaviour because these crabs normally return to their burrows when threatened at any other time.
Hope you enjoy learning a little about these interesting little creatures :)
Heading home tomorrow :((((((((((( lol Car
Early bird gets the.......crab! This shorebird is up before dawn hoping for a bubbler crab breakfast.
Sand bubbler crabs scour the sand to feed, and leaving sand pellets after scouring
This sand bubbler crab, Scopimera intermedia, was feeding in front of its burrow. You can see a sand pellet in front of its mouth.
They are almost the same colour as sand and as round as the sand balls they create. They bolt into their burrows at the slightest sign of danger. To observe them, stay still and avoid casting a shadow over them. Then look out for a moving ball of sand. Sand bubbler crabs eat the thin coating of detritus on sand grains.
