The scrawled cowfish, Acanthostracion quadricornis, is a cowfish in the family Ostraciidae. They range in size from 8-15 inches, with a maximum length of 18 inches, and can be found at depths between 6 and 80 feet. It is common to occasional in Florida and Bahamas; occasional to uncommon in the Caribbean. It may occur in the Gulf of Mexico, north to Massachusetts, Bermuda and south to Brazil in tropical and temperate waters.

Reproduction

The scrawled cowfish spawns during the months of January and February, and July through September. They release the eggs in pelagic waters and eventually settle as juveniles out of the water column.

Description

It has distinctive features such as a scrawled pattern of bluish markings covering its body; a blue line runs from snout to anal fin and it has a pair of sharp spines above each eye, giving the name “cowfish” because they resemble the horns of a cow. This latter point distinguishes cowfish from trunkfish. Overall it is colored blue-green to yellow cast. However, it may darken, pale and change color. Significantly it has two sharp spines in front of anal fin. Pelvic fins and spiny dorsal fin are not found on the cowfish. Almost always there will be dark, blotchy spots along the body, and three to four horizontal lines on the cheek. They have usually less than fifteen teeth in each jaw.

Habitat

Because the scrawled cowfish is a shallow water species, it will mostly always be found in and along grass beds. If disturbed it may remain motionless apparently relying on camouflage.

Diet

The scrawled cowfish likes to eat small invertebrates such as crabs and tunicates. It also will feed on some species of marine vegetation.

Importance to humans

Scrawled cowfish can be quite tasty if cooked properly. It is locally abundant in the Caribbean region and often sold fresh. Although they are very good to eat, in many places around the world they are used as an aquarium fish because of their beautiful coloration.
