In seagrass beds, on coral reefs, and in other marine habitats along the east coast of the Americas, a snorkeler or diver might spot the uniquely shaped scrawled cowfish (Acanthostracion quadricornis). This colorful fish has earned its name because the pointed appendages above its eyes resemble horns, and its profile and puckered mouth give it a cow-like appearance. This species is often called cowfish, trunkfish, or shellfish.
The scrawled cowfish lives in the Atlantic ocean as far north as Massachusetts in the United States, to Bermuda, throughout the Caribbean, the Gulf of Mexico, and south to Brazil. Living in shallow areas and to a depth of about 80 meters (260 feet), it feeds on invertebrates, vegetation, sponges, and small, slow-moving crustaceans. While the largest cowfish recorded measured about 56 centimeters (22 inches), the average length is about 20 centimeters (8 inches).
Lacking the scales of many fish, the scrawled cowfish’s body is covered with hexagonal-shaped dermal plates. These plates are fused together to form a hard shell covering.
The scrawled cowfish is not considered an endangered or vulnerable species by the International Union for Conservation of Nature (ICUN), and it is often prized as an excellent food fish, particularly around the Caribbean where it is abundant. Nevertheless, protection of natural seagrass beds and ocean waters is generally important for the scrawled cowfish and many other marine species, that depend on healthy habitats for survival.
