Hitchhiker Seaslug ID please!
March 13, 2003
From: Mok-Yi Chow
Hi!
This tiny sea slug came off my live rock as a hitchhiker. I never thought too much about him since I figured he'd probably perish after awhile... but 2 months later he is still alive and kicking, and actually got slightly bigger! I am wondering if you can help me ID him? I guess he is finding food in my aquarium.
Thanks!

It's a bit hard to identify these animals from underneath and with no idea where in the world they came from. However one possibility is the little chromodorid Durvilledoris lemniscata. These animals are specialised sponge feeders and so I wouldn't normally consider them as potential 'hitchhikers' if it weren't for Jim Roth's recent message. Perhaps they feed on a crevice-dwelling sponge, and because of their small size, only eat it fairly slowly.
Best wishes,
Bill Rudman
