Although both sexes range through temperate and tropical oceans and seas, only adult males populate higher latitudes. Sperm whales were mainstays of whaling's 18th and 19th century heyday. We use a variety of innovative techniques to study, protect, and rescue these endangered whales. We engage our partners as we develop regulations and management plans that encourage recovery, foster healthy fisheries, reduce the risk of entanglements, create whale-safe shipping practices, and reduce ocean noise. Only males tend to be observed closer to the poles beyond approximately 40° S or 40° N1,2. The sperm whale is the largest toothed whale.

Their heads make up one-third of their body length and are squarish in shape. At present the IWC has agreed estimates only for some species/areas.

NOAA Fisheries and our partners are dedicated to conserving and rebuilding the sperm whale population. Crude … Prior to whaling, sperm whales may have numbered 1.1 million worldwide, according to the American Cetacean Society.
Sperm whales are found in deep open waters, or around islands and coastal areas with deep canyons or very narrow continental shelves. It is estimated that the historic worldwide sperm whale population numbered 1,100,000 before commercial sperm whaling began in the early 18th century.
Increases or decreases in population are indicated within the table, where these have been identified. https://us.whales.org/whales-dolphins/species-guide/sperm-whale From that date until 1946 the population appears to have recovered somewhat as whaling pressure lessened, but after the Second World War, with the industry's focus again on sperm whales, the population declined even further to only 33 per cent.
Their skin is wrinkled to increase surface area for heat loss, giving them a shriveled look. The sperm whale prefers ice-free waters at least 3,300 feet (1,000 meters) deep.
