What's the background to these pictures. Do you know the photographer? They are very nice!

Cheers

Awesome! The pics belong in the Cat-eLog if only possible.

What are those things on the first cat's head? Crustaceans, barnacles like on whales etc.? Looks to me a bit like fish lice. Can be?

Thanks!

These photos are from a member (juanito22) of AqOL Forum.

This is the topic where he posted photos of this and other fishes photographed in the Malawi lake during your dive. Feel free to contact him if they wish. They really are beautiful photos!

They are not ectoparasites. Believe it or not, those are actually pits that are a normal part of the skin. Hence the specific epithet “foveolatus”.

Can't find the meaning/translation of foveolatus. What's that?

A google search got me to foveolate = pitted (having pits), which ties in with the explanation from HH.
