Alligatorfish Appearance

Alligatorfish have a slender, elongated body with overlapping bony plates covering their entire head and body.

Their body is more broad than deep, and it tapers from the head to the rear end.

The bony plates are smooth and arranged perfectly in longitudinal rows.

There are two large plates and many small ones in front of the pectoral fins.

Speaking of pectoral fins, they are bigger than dorsal, anal, and caudal fins.

The dorsal and anal fins of alligatorfish are fan-shaped, one above another. They are located at the center of the trunk.

The caudal fin is round and small in size, while the ventral fins are just one spine and two rays each.

Alligatorfish have large eyes with ridges above them, a small mouth, and tiny teeth.

There are also two sharp spines on their nose.

This fish is dark brown in color on top and light brown at the bottom.

There are two dark cross bands between the dorsal and pectoral fins.

There are also 2 to 3 cross bands between the caudal and dorsal fins and one below the dorsal fin.

Alligatorfish are around 5 to 8 inches long when fully grown.
