Mexican blindcat  (Prietella phreatophila)

Description

This small, rare fish, which possesses no eyes, inhabits underground waters in Mexico. The Mexican blindcat has a pinkish-white, smooth, scaleless body with four pairs of long, whisker-like barbels around the mouth (2) (3) (4). The adipose fin on the back is joined to the caudal, or tail, fin (2). Well-developed pores on the head (2), linked by canals, form the lateral-line, a sense organ used to detect movement and vibration in the surrounding water.
