'Lliving fossils' nautilus and allonautilus shaped by depths and diets over 500 million years
Why it matters: Understanding these ancient cephalopods could reveal new insights into deep-sea ecosystem resilience.
- Nautilus and Allonautilus cephalopods have existed for over 500 million years, thriving in the ocean's mesophotic zone.
- Researchers have spent 40 years studying these 'living fossils' to understand their survival mechanisms in nutrient-limited areas.
For over 500 million years, Nautilus and Allonautilus cephalopods have navigated the ocean's mesophotic zone, prompting researchers to investigate how these 'living fossils' sustain themselves in nutrient-scarce environments. Scientists have dedicated four decades to unraveling the mysteries behind their enduring survival and unique adaptations.
