ID Carnivorous Worm with Fishing Line

[sen5241b]

A few of my turbos came in with these weird worms on their shells. We noticed they cast out a slimy, little fishing line and I assumed they were filter feeders eating phytoplankton. Little did I realize they could chow on a live brine shrimp.

Spikey things are the worms. This particular turbo has many of these worms, some you can't see in photo.

Here is one of the worms sucking down a live brine shrimp. You can see the shrimp's little black eyes. Mmmm - Mm. At first I thought the shrimp was just stuck on the worm but I could definitely see the shrimp getting sucked in.

Yeah, small vermetids.

I hate them things. I get rid of as many as I can. They seem to spread quickly. Their webs drive me nut especially when they get on my corals.

Vermetid snails are usually found on rock since they bore holes in it.
I think those are hydroids.
