The skin is dusky gray above and paler below with white markings. A strong swimmer, it has a wide tail that has a double keel (a second, short ridge running along the upper part of the lower lobe of the tail). A double keel is unusual among sharks; the only other double-keeled tail is on the closely related porbeagle shark. Salmon sharks can grow to over 10 feet long, but the average is usually in the 6.5-8 ft range. Maximum recorded weights of salmon sharks are in excess of 660 pounds. Males mature at 5 years of age and females at 8–10 years. Salmon sharks have long gill slits and possess large teeth

How Are Salmon Shark Populations Doing?

The status of salmon sharks is one of the happier conservation stories in the shark world. They’re not widely sought after by commercial or sport fishermen, except for a very small sport fishery in Alaska. They are caught as bycatch by commercial fisheries, but studies have shown that their populations are stable, so fishing doesn’t seem to be especially detrimental. (Source: untamedscience.com)

Adw: Lamna Ditropis: Information

animaldiversity.org)Salmon sharks are widely distributed throughout coastal and pelagic environments within the subarctic and temperate North Pacific Ocean, between 10°N and 70°N latitude. Their range includes the Bering Sea, the Sea of Okhotsk, and the Sea of Japan, and also extends from the Gulf of Alaska to southern Baja California. Salmon sharks generally range from 35°N to 65°N latitude in the western Pacific ocean and from 30°N to 65°N in the eastern Pacific, with highest densities found between 50°N and 60°N.

Fact Sheet: Salmon Shark

The biology of the salmon shark (Lamna ditropis) The salmon shark is a commonly found species which can live both in coastal and oceanic regions, preferring cool, northern waters. Like several other species from the Lamnidae family, they can maintain their body temperature with the help of a vascular net (rete mirabilis) which maintains the water temperature around their bodies. They swim both underneath the water's surface and in depths of up to 150 meters. This species is found solitary or in schools and aggregate when feeding. (Source: www.sharkinfo.ch)
