Texas blind salamanders live in caves where little of not light penetrates. They have vestigial eyes which are covered over by skin as they aren't needed in this environment.
Scientific name: Eurycea rathbuni
Fewer than 100 of these cave dwellers remain in the world.
The crew set up specialist, cool lights that operate at low temperature to prevent the water temperature rising suddenly and to avoid any resulting change in the salamander's hunting behaviour. Fortunately, the shoot was successful - the same cave was off limits the very next day following rock movement overnight.

The Texas blind salamander (Eurycea rathbuni), is a rare cave-dwelling troglobite amphibian native to San Marcos, Hays County, Texas, specifically the San Marcos Pool of the Edwards Aquifer. The salamander has blood-red external gills for absorbing oxygen from the water. The salamander's mature length is 13 cm (5 in). Its diet varies by what flows into its cave, including blind shrimp (Palaemonetes antrorum), snails, and amphipods..
