Kogia breviceps species possess a dark gray coloration on their dorsal surface that lightens to white or pale gray on their ventral side, providing camouflage in deep ocean environments.
- 03
Deep-diving pygmy sperm whales hunt primarily on squid and fish at depths exceeding 400 meters, using echolocation clicks produced by their nasal structures.
- 02
Pygmy sperm whales possess a specialized spermaceti organ that comprises roughly 3 percent of their body weight, smaller proportionally than in their larger cousins.
- 01
