Kind: research · Impact: medium

## In brief

- New research led by Florida International University scientists was published in Nature Communications.
- The deep sea was previously thought to be immune to biodiversity crisis and a refuge for marine life.
- The study suggests that assumption may be wrong, pointing to hidden extinction risks there.

## Why it matters

If deep-sea species face extinction risks, marine conservation and biodiversity assessments that treat the deep sea as a refuge may need revising.
