The margined madtom (Noturus insignis) is a small type of catfish found in North American rivers. It belongs to a fish family called Ictaluridae. These little fish are known for living in clear streams and hiding among rocks.
What Does It Look Like?
The margined madtom has a body that can be yellow or dark gray on top. Its underside is usually a pale color. This fish is thinner than many other catfish in its family.
It has a unique square-shaped tail. Unlike some other madtoms, it doesn't have certain fin rays. Both its dorsal fin (on its back) and anal fin (on its belly) are rounded. The whiskers around its chin are light-colored, while its other whiskers are dark. Margined madtoms usually grow to be about 10 to 13 centimeters long.
Where Do They Live?
Habitat and Range
Margined madtoms live in clear-water streams. They like to find shelter among rocks, gravel, and large boulders. You can find this species from the Lake Ontario area all the way south to Georgia.
Life Cycle
Reproduction
Female margined madtoms lay many eggs at one time. After the eggs are laid, the male parent stays to guard them. This helps protect the young fish as they develop.
