That sounds like Gillman to me.

Gillmen are actually different from what you'd expect Mermen to look like (male Mermaids, effectively), as well...so I probably wouldn't go and change it to that.

I'm not sure if this is what the author actually intended, but it defintely seems like a fairly good possibility since it's also a fantasy creature.
