A goblin shark, Mitsukurina owstoni (family Mitsukurinidae), was captured in the northern Gulf of Mexico at 28°44.62′ N, 88°34.13′ W on 25 July 2000. The shark was captured by commercial fishers at 919 to 1,099 meters depth after it became entangled in fishing gear. The shark was female, the gut was empty, and no pups were present. Using regression analysis, the length was estimated to be 540 to 617 cm total length and may be the largest specimen collected to date. This capture from the Gulf of Mexico extends the goblin shark's range into the Atlantic waters of North America.
