The signs says:

The true seals or earless seals are one of the three main groups of mammals within the seal suborder, Pinnipedia. All true seals are members of the family Phocidae. They are sometimes called crawling seals, to distinguish them from the fur seals and sea lions of family Otariidae.

Phocids are the more highly specialized for aquatic life of the two groups and, unlike otariids, lack external ears and cannot bring their hind flippers under their body to walk on them.

They are more streamlined than fur seals and sea lions, and can therefore swim more effectively over long distances than those can. However, because they cannot turn their hind flippers downward, they are very clumsy on land, having to wriggle with their front flippers and abdominal muscles; this method of locomotion is called galumphing.

Additionally, true seals do not communicate by "barking" like the fur seals and sea lions of family Otariidae. They communicate by slapping the water and grunting.

That's very interesting. Now that you've read the sign, do you:
