Dwarf Sperm Whales: Tiny Creatures That Release Gutsful of Fluid When Alarmed
Dwarf sperm whales, the smallest whale species, defend themselves by releasing gallons of reddish-brown intestinal fluid when startled, which obscures predators' view and aids in escape. They inhabit deep tropical and temperate waters, feeding on deep-sea creatures, and are threatened by predators like sharks and orcas, as well as human activities.
