# New extensive sampling transforms our understanding of global marine diversity

## TL;DR

A new global eDNA study shows how little we know about marine biodiversity and highlights the need for more research.

## Contribution

The study presents extensive global eDNA sampling to reveal gaps in marine biodiversity knowledge.

## Key findings

- Global eDNA sampling shows significant gaps in marine biodiversity understanding.
- The study highlights the need for further research to address these gaps.

## Abstract

Scientists still have a very limited understanding of marine biodiversity. A new study in PLOS Biology using unprecedented global environmental DNA (eDNA) sampling reveals the extent of our ignorance and charts the way forward.

Scientists still have a very limited understanding of marine biodiversity. This Primer explores a new study in PLOS Biology that uses unprecedented global environmental DNA (eDNA) sampling to reveal the extent of our ignorance.
