Largest of the toothed whales, the deep-diving sperm whale is also the largest toothed animal in the world. The species name, macrocephalus, Greek for “big head”, describes one identifying characteristic of this whale. The male’s head is typically about one third its total body length (e.g., 5.2 m (17 ft) in a 15.4 m (51 ft) long male). The common name was derived from a milky-white substance called spermaceti contained in an organ in the whales’ head which was though to contain sperm. The size of the whale’s head is attributed to the size of this organ that can weigh 13.6 tonnes (15 tons) and contain 3.6 tonnes (4 tons) of oil.

- Amazing Facts
Ambergris is a foul smelling, fatty material produced in the lower intestine of some sperm whales apparently in response to irritation from accumulated squid beaks. It was highly prized for its ability to hold the delicate fragrance in expensive perfumes. On contact with air it took on a pleasant, musky odor. Synthetic materials have replaced its use in the perfume industry. Ambergris floats and today ambergris excreted by a sperm whale is occasionally found washed up on beaches. It is still valuable even though replaced by synthetics.
- At the Aquarium
Due to the space requirements for these intelligent and dynamic animals, we do not exhibit live whales or dolphins. The sperm whale is featured in Whales: Voices in the Sea, an interactive kiosk.
