Possibly to 8 m, world's largest predator. Generally in the open ocean, but does swim into shallower waters. Most attacks occurred in estuaries. Usually swims alone or in pairs but can be found in feeding aggregations. A versatile predator with a broad prey spectrum. Feeds on sturgeon and tunas, as well as sea lions and other large animals and fish (Ref. 9987). Presumably ovoviviparous. Reported by some experts to attack humans which they mistake for their normal prey of seals. Reported to cause poisoning (Ref. 4690). Meat is utilized fresh and smoked for human consumption, the skin for leather and the liver for oil (Ref. 9987).
