Unidentified Sea Slug in Poppe Images

It was unidentified in Poppe images... I'm just wondering if someone around here can identify this sea slug...

Pls. help if you can... Thanks!

This is often mistaken for a sea slug but it's a velutinid snail. I'm not sure what the right name is - possibly Coriocella hibyae. There seems to be a lot of confusion over the proper name even for the common ones. Go to nudipixel for a variety of photos and see if any of them match yours http://www.nudipixel.net/family/velutinidae/

Wow, I didn't realize that... Maybe it's Coriocella nigra...

Thanks for your help! I really appreciate it!

Gotta love that NudiPixel!
