FBname: Mexican blind brotula
Comments: Uncommon species found in caves and sinkholes (Ref. 34024).  Associated with the blind synbranchid fish <i>Ophisternon infernale</i> (Hubbs, 1938) and several blind crustacean species.  In only one cave, it was found with the catfish <i>Rhamdia guatemalensis</i> (Günther, 1864).  This species does not react to flashlights, but darted away at the slightest vibration; it seems to feed on troglobitic shrimps and mysids.  Newly-born juveniles are light yellow and about 20 mm long (Ref. 55786).
