Dromilites belli (Van Bakel, Robin, Charbonnier & Saward, 2017)

Dromilites belli is part of the family Dromiidae (often referred to as sponge crabs) which is still alive today. 

Members of the Dromiidae family are small or medium-sized crabs which get their name from the ability to shape a living sponge into a portable shelter for themselves. A sponge crab cuts out a fragment from a sponge and trims it to its own shape using its claws. The last two pairs of legs are shorter than other legs and bend upward over the crab's carapace, to hold the sponge in place. The sponge grows along with the crab, providing a consistent shelter.
