Scientists discover Antarctic krill living at deep-sea hydrothermal vents
Researchers observed egg-laden female krill at ocean hot springs for the first time, NPR reports.
The short version
- Researchers discovered Antarctic krill inhabiting deep-sea hydrothermal vents 3,600 feet below the ocean surface, marking the first time the species has been observed in this environment.[NPR]
- Scientists found egg-bearing females feeding on vent microbes and absorbing metals like manganese, which aids crustacean embryo development.[NPR]
- Experts emphasize that while krill demonstrate surprising behavioral flexibility, current evidence does not prove they depend on these vent habitats.[NPR]
Key facts
- Researchers observed egg-laden female Antarctic krill at deep-sea hydrothermal vents 3,600 feet below the surface in late 2024.[NPR]
- Stomach and tissue analyses revealed the krill fed on vent microbes and accumulated scarce metals like manganese, which supports crustacean embryo development.[NPR]
- A second expedition 1,000 miles away found another hydrothermal vent populated by egg-laden female krill two months later.[NPR]
What remains uncertain
- Whether krill actively depend on hydrothermal vents for reproduction or simply show environmental adaptability remains unproven.[NPR]
