The striped killifish is a small fish with dark stripes along its body. It lives in coastal waters and brackish bays on the east coast of North America.
The striped killifish differs from related species with clear dark stripes across its body and a preference for brackish water. It is important for nature as a link in the food chain: it eats small animals and serves as food for larger fish and birds.
Immature form that undergoes metamorphosis before adulthood.
