Short Description:

The sperm whale's distinctive shape comes from its very large head, which is typically one-third of the animal's length. The blowhole is located very close to the front of the head and shifted to the whale's left This gives rise to a distinctive bushy, forward-angled spray.
 
The flukes of a sperm whale as it dives into the Gulf of Mexico The sperm whale's flukes are triangular and very thick. The whale lifts its flukes high out of the water as it begins a dive.It has a series of ridges on the back's caudal third instead of a dorsal fin. The largest ridge was called the 'hump' by whalers, and can be mistaken for a dorsal fin because of its shape.

In contrast to the smooth skin of most large whales, its back skin is usually knobbly and has been likened to a prune by whale-watching enthusiasts. Skin is normally a uniform grey in colour, though it may appear brown in sunlight. Albinos have also been reported.
