Scientists found mystery bacteria inside one of the ocean’s most elusive whales
✦AI Summary
Researchers have identified three previously unknown genotypes of Helicobacter bacteria in pygmy sperm whales. The discovery was made by analyzing tissue samples from stranded whales over a 20-year period.
Pygmy sperm whales ( Kogia breviceps ) are some of the least understood mammals in the ocean. They spend most of their lives far from shore, usually traveling in small groups and diving deep to hunt squid and fish. Because they are quiet, secretive, and rarely seen at the surface, scientists have had few opportunities to observe them in the wild.
