San Quintin Blenny

Paraclinus walkeri

Unknown

Overview

Paraclinus walkeri, the San Quintin blenny, is a species of labrisomid blenny native to the coasts of Baja California Sur, Mexico. The specific name honours the fisheries biologist Boyd W. Walker (1917-2001) of the University of California, Los Angeles who placed his specimens at the disposal of Clark Hubbs.

Paraclinus walkeri faces severe threats from coastal development and pollution in its extremely limited range around the Caribbean. The species' restriction to shallow reef environments makes it particularly vulnerable to coral bleaching events and ocean acidification. Overfishing and destructive fishing practices in its habitat further compound population pressures on this already rare blenny.

Threat summary

Habitat

Paraclinus walkeri inhabits shallow coral reefs and rocky substrates in tropical Caribbean waters, typically found among crevices and coral formations at depths of 1-15 meters. The species shows a strong preference for areas with abundant coral cover and complex reef structure that provide shelter and feeding opportunities.
