Evidence

Peer-reviewed

Geography

Canary Islands, Spain

System

Coastal shark nurseries / predator-prey systems

## WHAT THE EVIDENCE SAYS

A validated citizen-science observation network documented six attacks or attempted attacks on juvenile angelsharks by three ray and skate species from 2020–2025\. Nursery habitat still contains native predator–prey interactions.

## WHY IT MATTERS / OUR READ

Ecological nursery protection should preserve a functioning food web rather than treat every predator of a rare species as a management enemy.

## CAVEATS / UNCERTAINTY

The opportunistic sightings cannot quantify attack frequency, mortality rates or population effects and do not justify ray control.
