Does Alaska Have Sharks?
Alaska is not the first place that comes to mind when thinking of sharks, but these apex predators can be found in the cold waters of the state.
The most common shark species in Alaska waters are the Pacific sleeper shark, the salmon shark, and the spiny dogfish.
The Pacific sleeper shark is a slow-moving, deep-water species that can grow up to 23 feet in length. They are known for their ability to regulate their buoyancy, allowing them to rest on the seafloor for extended periods. Despite their size, they are not considered a threat to humans.
The salmon shark, on the other hand, is a faster and more active species that can grow up to 10 feet in length.
They are named after their primary prey, the Pacific salmon, and are often found in the same areas as the fish. While they have been known to attack humans, such incidents are rare.
The spiny dogfish is a smaller species that can grow up to 4 feet in length. They are found in both deep and shallow waters and are known for their sharp spines, which can be dangerous to fishermen.
They are also a popular food fish and are harvested commercially.
Specific Shark Species

Salmon Sharks
Salmon Sharks (Lamna ditropis) are a common species in the waters off Alaska. They are named for their diet, which includes salmon.
These sharks are known for their high body temperature, which allows them to swim in colder waters than other species.
Pacific Sleeper Sharks
Pacific Sleeper Sharks (Somniosus pacificus) are a large species of shark that are found in the deep waters off Alaska.
They are known for their slow metabolism and ability to survive in the cold, dark depths of the ocean.

Blue Sharks (Prionace glauca) are a common species in the waters off Alaska. They are known for their distinctive blue coloration and their long, slender bodies.
These sharks are often caught by commercial fishermen.
Spiny Dogfish
Spiny Dogfish (Squalus acanthias) are a small species of shark that are found in the waters off Alaska.
They are known for their sharp spines, which can be dangerous to humans who handle them. These sharks are often caught for their meat.
Six-Gill Sharks
Six-Gill Sharks (Hexanchus griseus) are a large species of shark that are found in the deep waters off Alaska. They are named for their six gill slits, which are a unique feature among sharks. These sharks are rarely seen by humans.
Basking Shark
Basking Sharks (Cetorhinus maximus) are a large species of shark that are found in the waters off Alaska.
They are known for their massive size and their habit of swimming near the surface of the water with their mouths open, filtering plankton from the water.
Thresher Shark
Thresher Sharks (Alopias vulpinus) are a species of shark that are found in the waters off Alaska.
They are known for their long, whip-like tails, which they use to stun their prey. These sharks are often caught by commercial fishermen.
Mako Sharks
Mako Sharks (Isurus oxyrinchus) are a species of shark that are found in the waters off Alaska.
They are known for their speed and agility, which make them formidable predators. These sharks are often caught by sport fishermen.
Requiem Sharks
