Sperm Whale
Seen in nearly all marine regions, the Sperm Whale has a large range but are found typically in areas with deep water. The Sperm Whale suffered massive losses through whaling, which met its peak in 1950, where 25,000 were killed each year.
Whales are also susceptible to being caught in fishing gear, particularly gillnets.
Because of the gestation rate of Sperm Whales, increasing the population would be incredibly slow, and the effects of whaling will be felt for many years within the species.
