Redfin Blue-eye

[edit] Overview

A critically endangered species, this tiny 1-inch (2.5 cm) survives in shallow artesian springs in hot, dry, grassy country where the air temperatures range from 51 degrees C to 3 C (124 to 37 degrees F).

Fewer than 3,000 Redfin Blue-eyes are believed to survive in about five springs. It fails to compete well with the exotic Mosquito Fish (Gambusia holbrooki) which has been introduced into some waters in its native range.

Other threats include well-drilling in artesian springs and the impact of grazing animals on the shallow habitat favored by this species.

Bush Heritage Australian, a non-profit land preservation organization, has recently acquired a lease on the lands where this species is found to help ensure its protection.
