About Sixgill Shark

The sixgill shark, also known as the bluntnose sixgill shark, is a large shark species found in tropical and temperate waters worldwide. They are members of the Hexanchidae family. Currently, the sixgill shark is listed as Near Threatened on the IUCN Red List. Although common, they are vulnerable to over-fishing.

Appearance and Size

Bluntnose sixgill sharks have a unique appearance. They can grow up to 20 feet long. The average weight of a bluntnose sixgill shark is 800 to 1,100 pounds. They have a large body and a long tail. As their name suggests, they have blunt and wise snouts. They also have small florescent green-blue eyes. Bluntnose sixgill sharks have six rows of sharp teeth on their lower jaw and smaller teeth on their upper jaw. Their coloration varies. Some bluntnose sixgill sharks are grey, tan, or brown-black.

Distribution and Habitat

You can find bluntnose sixgill sharks throughout the world and Washington State. According to the Washington Department of Fish and Wildlife, bluntnose sixgill sharks live from the Aleutian Islands, Alaska to Baja California, Mexico in the Eastern Pacific. Typically, these sharks dive deep up to 6,152 feet. Although they spend most of their lives in the deep sea, they sometimes wander to shallow waters looking for food. 


So, what do these sharks typically eat? Sixgill sharks are nocturnal feeders. They consume large bony and cartilaginous fishes. Common animals in their diet include dolphins, other sharks, skates, squids, crabs, and rays.


Because of their size, sixgill sharks have few to no natural predators. They may be hunted by great white sharks and killer whales. Young bluntnose sixgill sharks are more vulnerable than adults. Sometimes, other sharks, dolphins, and Stellar’s sea lions prey on young sixgill sharks.

Other Sharks in Washington

Although sixgill sharks are becoming more common in Washington State, they are still rare to see. These sharks mainly live in the deep sea. Instead, other shark species are more common. Along the coast of Washington State, there are at least 14 shark species. Listed below are a few you can keep your eye out for!

Great White Shark

The first shark on our list is the most well-known shark in the world, the great white shark. It’s also very misunderstood and has been painted as a vicious villain/animal for decades in films and series. Although most shark attacks are from great whites, attacks are still rare. In Washington State, great whites are occasional visitors. They rarely venture into Washington’s Puget Sound, but they are still there!
