Oebalia unistriata

Unknown

Overview

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

Oebalia unistriata faces significant pressure from coastal development and habitat modification along Mediterranean shorelines where it occurs. The species is particularly vulnerable to pollution from urban runoff and marine debris, which can alter the sediment composition of its preferred sandy and muddy substrates. Climate change-induced sea level rise and increased storm intensity threaten to disrupt the shallow coastal environments essential for this small sea urchin's survival.

Threat summary

Habitat

Oebalia unistriata inhabits shallow coastal waters of the Mediterranean Sea, typically found in sandy and muddy substrates at depths ranging from the intertidal zone to approximately 50 meters. The species prefers areas with fine sediments where it can burrow and feed on organic matter and small invertebrates.
