(Physeter macrocephalus)

These whales were given their common name because of a waxy liquid called "spermaceti" located in their head.

Sperm whales live at least 60-70 years.
Sperm whales form “nursery schools” that contain between 20 and 30 whales; females, calves, and juveniles (male and female).
The brain of a sperm whale is the largest of any animal, about 9 kilograms.

Adult males (bulls) reach 15.24 metres (50 feet) in length and weigh 54,400 kilograms (120,000 pounds, 60 tons).
Adult females (cows) reach more than 36 feet and weigh 25,000 kilograms (55,000 pounds, 27.5 tons).
Newborn (calves) are about 13 feet long and weigh only 1,000 kilograms (2,200 pounds, 1.1 tons).
- a calf is born to a female only every 4-6 years.
- calves stay with the mother for between 1 and 2 years.
