Seals are a well known animal and live mainly on the beach. There are 18 different types of seals, and the biggest is the southern elephant seal. They are usually about 6 metres. Male seals are usually much bigger than female seals. The smallest seal is the ringed seal, and is 1.5 metres long. Seals normally live from 25-30 years, and just like humans, females live longer than men. Seals are carnivorous animals and like to eat squid, crustaceans, herring and salmon. Seals are fun and playful, but baby seals are dying due to us picking them up. Seals are cute animals, but we still need to be cautious about how we treat them.
