Animal crossing new horizons teach me different types of fish. The most common fish we fish up are black bass and sea bass. All the fish you fish up have a joke they write down. There are sharks too. I caught the great white shark, the whale shark, a hammerhead shark and a saw shark. There is also a fish called a sucker fish because it sucks the sharks stuff, not because it sucks. I love those fish, especially the oarfish.
