Antarctic krill have been observed feeding at deep‑sea hydrothermal vents, a habitat previously thought unsuitable for the tiny crustaceans. The discovery suggests a hidden food source that could alter how scientists view krill distribution and the broader oceanic food web.

National Geographic reports that explorer teams spotted active feeding, while nature.com and Phys.org describe gravid individuals clustering around the vents, indicating the sites may serve as a reproductive hotspot. The unexpected presence raises immediate questions about the environmental factors drawing krill to these extreme locales.

Researchers plan targeted sampling and genetic analysis to determine whether vent chemistry, thermal gradients, or prey availability drive the aggregation. Ongoing expeditions by the National Geographic Society and partner institutions will monitor krill activity, aiming to resolve the open question of why these cold‑adapted animals venture into such hot environments.

Quick answers

Where were the krill observed?

They were found at deep‑sea hydrothermal vents, as reported by National Geographic and other outlets.

What stage of krill were detected at the vents?

Gravid (pregnant) Antarctic krill were documented clustering around the vents, according to nature.com and Phys.org.

What are scientists planning to do next?

Researchers say they will conduct further sampling and genetic analysis to investigate whether vent chemistry, temperature or prey availability explains the aggregation.
