Good day all,

Im trying to ID what looked like a worm hanging on to a bit of coral, about 3 inches long at 40 feet deep and what all the little things running around in the dive torch where during my dive. I got so annoyed at them by the end i became a mass murderer and fed loads of the them to any Basket starts i found by shining my light near it and watching the slaughter!

Video of mass murder here - imgur.com (cant embed for some reason??)

Thanks

Bloodworms.

They're little polychaete worms that wiggle up from the sand and mob any light source.

The red worm is a Bearded Fireworm, a bristle worm. Those white bristles are sharp, will penetrate your skin, inject a toxin and break off in your skin. Don't touch!

The first image is a fireworm It often feeds on the gorgonian.
