Eviota ocellifer

Declining

Overview

Eviota ocellifer is a small marine goby fish belonging to the family Gobiidae, characterized by its diminutive size and distinctive ocellated markings. This species inhabits shallow coral reef environments in the Indo-Pacific region, where it occupies specific microhabitats among coral formations and rocky substrates. Like many members of the Eviota genus, E.

ocellifer exhibits cryptic behavior and relies on coral reef ecosystems for shelter, feeding, and reproduction. The species is currently classified as Critically Endangered by the IUCN, with populations showing a decreasing trend. The primary threats to E.

ocellifer include coral reef degradation caused by climate change, ocean acidification, and rising sea temperatures that lead to coral bleaching events. Coastal development and pollution further compromise the quality of reef habitats essential for the species' survival. The limited distribution range of this goby makes it particularly vulnerable to localized environmental disturbances and habitat loss.

Marine protected areas that encompass coral reef ecosystems provide some level of protection for E. ocellifer populations, though targeted conservation measures specifically for this species remain limited. Research efforts focus on better understanding the species' ecology, population dynamics, and specific habitat requirements to inform conservation strategies.

The preservation of healthy coral reef ecosystems through climate change mitigation and local conservation initiatives represents the most effective approach to ensuring the long-term survival of this critically endangered goby species.

Eviota ocellifer faces severe threats from coral reef degradation driven by climate change, including ocean warming and acidification that cause coral bleaching. Coastal development and marine pollution further degrade the reef habitats this species depends on for survival. The species' limited distribution makes it especially vulnerable to localized environmental disturbances.

Frequently asked questions

Why is Eviota ocellifer classified as Critically Endangered?
Eviota ocellifer 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. Eviota ocellifer faces severe threats from coral reef degradation driven by climate change, including ocean warming and acidification that cause coral bleaching. Coastal development and marine pollution further degrade the reef habitats this species depends on for survival. The species' limited distribution makes it especially vulnerable to localized environmental disturbances.
Where does Eviota ocellifer live?
Eviota ocellifer occurs in France, and Japan. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Eviota ocellifer?
The main threats to Eviota ocellifer are 9.3.4. The full IUCN-classified threat record for this species is detailed on the species page.
