Animals that have huge foreheads are always amusing to see. They look funny and somehow remind us of our weird-looking uncle Stanley (thank god we didn’t inherit our foreheads from him).
Land animals with huge brows are common to find, but did you know that there are even more fish with big foreheads?
These include many species of cichlids like the Midas cichlid and the kamfa, many species of dolphinfish, napoleon fish, humphead parrotfish, oranda, humphead glassfish, unicornfish, and others.
Let’s explore all of these animals and show you what they look like.
