P. catodon: The Sperm Whale or Cachalot. All oceans. Male may reach 60 feet, the female usually half the length of the male. This is the whale that has suffered the relentless persecution of whalers, always a coveted prize on account of its spermaceti-permeated blubber, and its excretory ambergris. The most dangerous of whales.
