• Until the late 16th century sharks were usually referred to in the English language as sea-dogs. The name "Shark" first came into use around the late 1560s to refer to the large sharks of the Caribbean Sea.

• Some sharks, if inverted, enter a natural state of temporary paralysis called tonic immobility. Researchers use this condition for handling sharks safely.

• The name shark may have originated from the Mayan word for shark, xoc, pronounced "shock" or "shawk"

• The teeth of carnivorous sharks are not attached to the jaw, but embedded in their flesh, and in many species are constantly replaced throughout the shark's life.

• Even though the basking shark is considered to be slow and very large it can actually breach the water, i.e. jump fully out as some whales do.

• Despite the common myth that sharks are largely instinct driven "eating machines", recent studies have indicated that many species possess powerful problem-solving skills, social complexity and curiosity.
