Juvenile fish eating jellyfish

Bob Halstead took this photo during my recent trip in Milne Bay, PNG. It appears to be a juvenile fish eating a small jellyfish.

Does anyone happen to recognize this fish?

Looks like a juvenile jack (family Carangidae), I will try to find out.

Alright, I think it is a juvenile Uraspis helvola.

Thanks Luiz. From a quick google search, that looks right!

I'll pass that on to Bob.

Cheers,

Tony
