Nereiphylla paretti

Check out this beauty!

Nereiphylla paretti is a 30 cm (foot) long worm from European waters like the North Sea, English Channel and Mediterranean. They're active predators who scour the shallows in search of prey.

Nereiphylla paretti is an annelid, or segmented worm, so-called because its body is divided into segments.

More precisely it's a polychaete, also known as a bristle worm, because each segment bears a collection of tough bristles sprouting out of the sides.

Even more precisely it's a Phyllodocid, or paddle worm, because some of those bristles have turned into large, flattened paddles.

I don't know what these paddles are for but man, when each one is edged with yellow it sure looks pretty!

I bet the plates are excellent for when they 'hunker down' in a crack to keep away from predators.

They can really squish themselves in there so it could just be a wall of plates jammed into the sides of a crack from above.

@Lear's Fool: Ooooo, could be. Good thinking!

@TexWisGirl: I doubt it glows in the dark but it sure looks like it should!

Before I looked closely, I thought it had a bunch of little yellow centipede legs, and I was terrified.

Ha! It does look like that! Weird how lots of legs seems way more scary than lots of paddle things
