An older sketch of the Asian Upside-Down #Catfish. It’s called that because it spends most of its life swimming on its back and it has a really cool adaptation to show for it!
You may notice that many animals have an underbelly that is a lighter color than the rest of their body. This is called countershading and helps them blend in with their environment. Well, due to its unique lifestyle, this #fish is reverse-countershaded and its belly is much darker than its back!
