Tenellia sp. 51 (in NSSI) Undescribed

Previously Cuthona sp. 51, this species was brought to our attention by Scott Johnson from the Marshall Islands. It is actually one of the larger Tenellia species, reaching up to 25mm in length.

The body is brownish-orange with pales areas between the ceratal groups. It has white oral tentacles, rhinophores and cerata. The latter two have orange bands.

Keep your eyes open for this critter and let us know what hydroid it feeds on. Love to learn more about it.

Thanks for sharing Jim!

There are a lot of kids in the formative stage of their education who are getting their first introduction to our sea slug friends via the great photographs Jim and other contributors have made to the site. My hat is off to Jim for making this presentation possible!
