What Are Some Different Kinds of Seals?

There are 32 different types of seals in the world of which the elephant seal is the largest. These animals can weigh upwards of 2 tons. The smallest type of seal, the Galapagos fur seal, has an average weight of only 65 pounds.

Harbor seals, sometimes referred to as common seals, have one of the largest ranges of all seals. They are often found on rocky or sandy beaches in large numbers. Gray seals are another type, typically averaging around 600 pounds when fully grown.
