Mariana Skink

Emoia slevini

Declining

Overview

Emoia slevini, also known commonly as the Mariana skink, Slevin's brown skink, Slevin's emo skink, and Slevin's skink, is a species of lizard in the family Scincidae. The species is endemic to the Mariana Islands.

Emoia slevini faces severe threats from habitat destruction on its limited Pacific island range, where coastal development and infrastructure projects have eliminated much of its native forest habitat. Introduced predators, particularly cats and rats, pose significant predation pressure on this ground-dwelling skink. Climate change and sea-level rise threaten the low-lying coastal areas where remaining populations persist, while the species' extremely restricted range makes it vulnerable to catastrophic events.

Threat summary

Habitat

Emoia slevini inhabits coastal forests and woodland areas on Pacific islands, typically found in leaf litter and low vegetation near the forest floor. The species prefers areas with dense canopy cover and is associated with both native forest remnants and some modified habitats with adequate shelter.

Frequently asked questions

Why is Mariana Skink classified as Critically Endangered?
Mariana Skink 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. Emoia slevini faces severe threats from habitat destruction on its limited Pacific island range, where coastal development and infrastructure projects have eliminated much of its native forest habitat. Introduced predators, particularly cats and rats, pose significant predation pressure on this ground-dwelling skink. Climate change and sea-level rise threaten the low-lying coastal areas where remaining populations persist, while the species' extremely restricted range makes it vulnerable to catastrophic events.
Where does Mariana Skink live?
Mariana Skink occurs in Guam. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Mariana Skink?
The main threats to Mariana Skink are 2.1, 2.3, 8.1, and ai-1. The full IUCN-classified threat record for this species is detailed on the species page.
