Kids' Inquiry of Diverse Species

Local animals in this group:

Percopsiformes

The trout-perches, pirate perch, and cave fishes is a small group of small, North America, freshwater fish. There are 9 species in 3 families: 1 pirate perch, 2 trout-perches, and 6 species of North American cave fishes. The cave fishes are particularly fascinating, they have all become blind and eyeless, as they cannot see in their utterly dark cave environments.
