DID YOU KNOW?
True Seals Vs. Fur Seals: There are two types of seal: true seals and fur seals. True, or earless, seals are more specialized for aquatic life than fur seals, which are more closely related to sea lions.
The Streamlined Seal: True seals have ultra-streamlined bodies compared to fur seals. They lack external ears, can retract their nipples, have internal testicles and their penis lies in an internal sheath.
Seal Songs: Seals "sing" underwater, sometimes lengthy songs over a minute long. Scientists believe this behavior is either related to underwater navigation or hunting.
Small to Large: Topping out at around 140 pounds, the Galapagos fur seal is the world's smallest pinniped (fin-footed mammals). At up to 11,000 pounds, the southern elephant seal is the largest.
