Seals

Seals are marine mammals that spend some of their time on land and some of their time in the water. Seals can be broken into two main groups, called eared seals and earless seals. Within these groups, dozens of different seal species are recognized. These seal species are a variety of sizes and colors. They can range from four to 16 feet long and weigh between 100 and 2,400 pounds, depending on the species.

Different seal species also live on different areas of the planet. Although many seals live in colder arctic or temperate areas, there are also some tropical seal species.  Seals are mammals, meaning they breathe air. However, seals are excellent swimmers and can hold their breath for minutes at a time. Seals dive deep beneath the ocean’s surface to catch fish, which is usually the main staple of their diet.
