Paromola cuvieri is a species of crab belonging to a group known as carrier crabs.
Carrier crabs just LOVE to carry things.
They’re specially adapted for it, too. Their hindmost legs are positioned in such a way that they point straight up and can hold sponges or lumps of coral aloft.
Presumably it helps with camouflage so they just look like a sponge with massive crab legs sticking out for no discernible reason.
This particular species comes from deep, dark depths near Europe and Africa, and they reach about 20 cm long. Males have enormous claws that can span as much as four feet! Good luck hiding that.

Unlike land mammals, dolphins sleep with only part of their brains at any time, past research has suggested. Half of their brains rest, while the other half remains “awake,” and dolphins regularly switch which side is active.
“After being awake for many hours or days, humans and other animals are forced to stop all activity and sleep,” said researcher Brian Branstetter, a marine biologist at the National Marine Mammal Foundation in San Diego. “Dolphins do not have this restriction, and if they did, they would probably drown or become easy prey.”
