fatchance:

A few of the oysters I shucked were hosting tiny oyster crabs (Zeops ostreus), a common parasite of oysters and other bivalves in east coast waters. The crabs graze on plankton the oysters siphon to feed themselves.
Over time a crab can damage an oyster’s fleshy mantle, but they are harmless to people, aside from being, well, alarmingly ugly, and (such a fraught word) parasites. I am an aquatic biologist not bothered by such things, and I find them interesting, if not attractive.
The specimen above was about a centimeter wide. You can easily visualize internal organs through its translucent shell. Based on the small size of its eyes, I think this little crab is female.

Whale Fall: The afterlife of a whale.

An exquisite cut-paper animation about the decay and proliferation of deepwater life on the dead body of a whale. The phenomenon, also termed a whale fall, is a massive boon for deep sea scavengers, which often have to rely from transported nutriments from somewhere else.

Directed by Sharon Shattuck and Flora Lichtman.
