Deep-sea mussels show day-night body clock rhythms
Original: Internal clocks of deep-sea mussels tick to a day-night rhythm
Researchers report that deep-sea mussels maintain internal clocks synchronised to a day-night rhythm, despite living in environments where sunlight barely reaches. The finding suggests circadian timing persists in deep ocean species, raising questions about how such rhythms are maintained without direct light cues. Marine biologists say the result could reshape understanding of biological timing in deep-sea ecosystems.
Why now: New research surprises readers because circadian rhythms are usually tied to sunlight, which is largely absent in the deep sea.
