Caught in passing

I was watching hermit crabs in the aquarium when a red worm zipped by.


Spiny polychaete. Each "foot" is tipped with a brush, and armed above with a long spine.
He's tiny; on the right, three copepods are playing. They're about a millimetre long. The round dots along the edge of the shell are oyster eyes. And I don't know what that yellow and black striped creature (or tentacle, or foot) is, peeking out from between the folds of the oyster shell.

A large isopod reached out from a seaweed clump to investigate a mass of green-centred bubbles, probably disintegrating algae.

These isopods are plentiful under rocks and clutching rockweed in the intertidal zone. Sometimes they come home with me; they live happily in the tank for a while, until a crab catches them for dinner. As long as there is at least one branch of rockweed, they stay out of reach.

    1. You mean the isopod and the algae? Good crab diet!

Also, I have word verification on, because I found out that not only do I get spam without it, but it gets passed on to anyone commenting in that thread. Not cool!
