This was posted somewhere else, and I wanted to know if anyone here could help with an ID. The snake was caught in a net off the cost of India.

dont think that is actually a snake, looks like some sort of eel to me

Looks like a nudibranch (sea slug). Definitely some type of invert.

The raised tail fin (I'm not sure on the appropriate term) designed for locomotion makes me think it's a vertebrate more so than a sea slug. I'm not well versed on sea snakes or eels, but I'd lean towards eel.

From what I know, sea snakes are very, very roughly keeled (as are all water snakes it seems, yes?). This looks very smooth, flat, and not scaled, further giving the impression of an eel.

I thought the same thing actually, but the person who posted it titled it as "Can anyone identify this sea snake" so I basically did the same.

Looks like a brown spotted moray eel (Gymnothorax reevesii) to me.

Found commonly near India, Malaysia, and Indonesia.

I agree... Eel.
