Lovely shots Melvyn- how big are the crabs?- I assume pretty small judging by the size of the sand grains.

I'm pretty certain they make these little sand balls as they feed by removing any scraps or algae etc from the sand grains. Presumably this helps them know what sand they have already sifted :)

That's a great series, Melvyn. Was all this the work of just 1 crab? Also, how close is this to the water?

Thes crabs sift the sand through there mouth to get micro organisms. Yes all this is done by one crab in just a few hours. When the tide comes up the crab goes back into the burrow and the balls get washed away. In this family of crabs there are much larger ones that do the same thing. Very interesting pictures Melvyn.

As Matthew has mention, it's the work of one crab. As the tide is low, this is about 4m from the shoreline:D

Facinating !
These little critters looks fantastic

The frame is a bit too birght in my opinion (and my screen is calibrated)
but still it's very very well done by POV and Technical aspect
