Shortnose Eagle Ray

Myliobatis ridens

Declining

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Myliobatis ridens faces severe population decline primarily due to intensive fishing pressure across its limited range in the Western Atlantic. The species is particularly vulnerable to bottom trawling and gillnet fisheries that target demersal species in coastal waters. Habitat degradation from coastal development and pollution further compounds these pressures, while the species' slow reproductive rate limits its ability to recover from population declines.

Threat summary

Habitat

This eagle ray inhabits coastal and continental shelf waters of the Western Atlantic, typically found over sandy and muddy bottoms in depths ranging from shallow nearshore areas to approximately 200 meters. The species prefers temperate and subtropical waters where it forages for benthic invertebrates including mollusks and crustaceans.

Frequently asked questions

Why is Shortnose Eagle Ray classified as Critically Endangered?
Shortnose Eagle Ray is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Myliobatis ridens faces severe population decline primarily due to intensive fishing pressure across its limited range in the Western Atlantic. The species is particularly vulnerable to bottom trawling and gillnet fisheries that target demersal species in coastal waters. Habitat degradation from coastal development and pollution further compounds these pressures, while the species' slow reproductive rate limits its ability to recover from population declines.
Where does Shortnose Eagle Ray live?
Shortnose Eagle Ray occurs in Argentina, and Brazil. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Shortnose Eagle Ray?
The main threats to Shortnose Eagle Ray are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
