Scrawled Cowfish
Acanthostracion quadricornis
The scrawled cowfish is a boxy reef fish with a rigid armor-like body and prominent hornlike spines. It lives in warm Atlantic waters, including reefs, seagrass, and mangrove edges, and can release a toxin if stressed or handled.
Identification points
- Boxy, rigid body enclosed in bony plates rather than a flexible shape
- Usually pale tan to yellow with irregular dark, scribbled or blotchy markings
- Four hornlike spines: one above each eye and one at each rear corner of the body
Habitat
Shallow tropical and subtropical western Atlantic habitats: coral and rocky reefs, seagrass beds, mangrove edges, and sand flats near structure, usually from very shallow water to about 30 m.
Bait notes
Rarely targeted as a game fish; if hooked, it may take small natural baits like shrimp, squid, or bits of crab on light tackle. Small jigs or baited hooks around reefs and grass edges can catch one incidentally.
Behavior
A slow, deliberate forager that picks at small benthic invertebrates such as mollusks, crustaceans, worms, and algae. It is generally solitary or seen in pairs and relies on its armored body and toxins rather than speed.
Caution
Do not handle roughly: when stressed, cowfish can release ostracitoxin into the water, which can kill nearby fish in confined areas. Not a common food fish; avoid consumption unless local guidance confirms it is safe.
Fishing notes
Fish near bottom structure with light leaders and small hooks; use subtle presentations because it feeds cautiously. Handle minimally and keep it in water when possible, as stress can trigger toxin release.
