Are sea dogs seals?

Seals: North Sea dogs are distributed in the North Pacific Ocean, often inhabiting the Kuril Islands, the northern hemisphere waters north of 35 north latitude, and occasionally found in the Yellow Sea and East China Sea.

Seals: Seals are distributed in the Arctic, around the Antarctic and in temperate or tropical waters. Seals are mainly distributed in cold polar waters, and Antarctic seals live in Antarctic ice sources.

Extended data:

Seals have a wide range of food sources, mainly cephalopods, eastern cod, Alaska cod, trout, octopus, wolffish and various sea squirts.

When hunting fish, seals will dive into the water, quietly follow the prey and then bite the prey. Seals can't chew, so they either swallow food directly or tear it into small pieces. It is particularly interesting that seals often find stones in their stomachs, weighing 200-400 grams.

Seals usually live on fish, but they also eat crustaceans and cephalopods. Seals swim very well, with a speed of 27 kilometers per hour. At the same time, they are good at diving. Generally, it can dive about 100 meters, while the Weddell seal in Antarctic waters can dive more than 600 meters deep for 43 minutes.

Seals mainly prey on all kinds of fish and cephalopods, and sometimes they also eat crustaceans. They eat a lot. A seal weighing 60-70 kilograms eats 7-8 kilograms of fish a day.
