What is arrow-tooth flounder?

Arrowtooth flounder (Atheresthes stomias) is a species of marine fish that belongs to the family Pleuronectidae. It is also known as the flathead flounder, Pacific arrowtooth flounder, or hirame.

Arrowtooth flounder can be found in the northeastern Pacific Ocean, from the Bering Sea to the coast of California. They are one of the most abundant and commercially important species of flatfish in the North Pacific, with a lifespan of up to 20 years.

They have a distinctive arrow-shaped tooth on their upper jaw, which is used to catch and eat prey such as small fish, shrimp, and squid. Arrowtooth flounder can grow up to 1.2 meters in length and weigh up to 10 kilograms.

Arrowtooth flounder are an important part of the commercial fishing industry in Alaska and are frequently caught by bottom trawl or longline fishermen. They are also an important food source for marine mammals such as sea lions and killer whales. Despite being abundant, the arrowtooth flounder's population is being monitored due to overfishing concerns.
