Nudi ID? They all look the same in this darn book! (pic)

[Matt S.]

Seen today at Cove 2 in 45-60 fsw, if memory serves. Approx 2" long. Some kind of flabellina?



Thanks for the help!

It looks like a Opalescent Nudibranch to me....

I think it is an Opal rather than the Flabellina due to the orange found on it.

Cool Facts-

"Opalescent nudibranchs are aggressive fighters. When two of them meet head-to-head, they’re likely to lunge into a biting battle. If one meets the tail of another and gets the first bite, it usually wins the battle and consumes the loser.

Because opalescent nudibranchs live less than one year, they have to grow and reproduce quickly—they can’t lose time looking for a mate. A meeting between two or more can be a mutual mating session, since these creatures are hermaphroditic (they have both male and female sexual organs). Later, each lays an egg string in narrow coils that looks like tiny sausage links. They attach their eggs to eelgrass and algae"
