Briefings

A 2026 study led by Senckenberg researchers analyzed the genomes of the Antarctic spiny plunderfish (Harpagifer antarcticus) to identify mechanisms for survival in extreme Antarctic temperatures. The study used the first time to separate maternal and paternal genome copies, revealing specific adaptations to the Southern Ocean's -1.9°C water temperature.

Key points

• Researchers used the Antarctic spiny plunderfish (Harpagifer antarcticus) as a model organism to study cold adaptation.
• The study analyzed maternal and paternal genome copies separately for the first time.

Context

The Southern Ocean faces extreme conditions with water temperatures as low as -1.9°C (28.6°F). This research provides insights into how fish species survive such cold environments.

Limitations

The study is limited to the Antarctic spiny plunderfish model organism. The specific genetic mechanisms identified are preliminary and require further validation.
