A Pugheaded Cobia (Rachycentron Canadum) From The Northcentral Gulf Of Mexico, James S. Franks
Gulf and Caribbean Research
A pugheaded cobia (Rachycentron canadum) captured in the northcentral Gulf of Mexico represents the first record of pugheadedness in cobia. The specimen, a 4-year-old gravid female, exhibited considerable distortion of the premaxillary and maxillary bones, with the length of the snout 46% shorter than that of a normal cobia of the same length. The anomaly had no apparent effect on feeding, since the stomach contained a substantial amount of food, and the fish was the same length expected of a normal 4-year-old cobia.
