Mexican blindcat (Prietella phreatophila) at the Conservation Department of the San Antonio Zoo.
This species is endangered on the IUCN Red List as well as on the US Federal list.

This stygobitic catfish is known from about a dozen sites in Coahuila, Mexico and is listed as endangered in both Mexico and the United States. A single population (represented by this individual) was recently discovered in Val Verde County, Texas, after two decades of searching by cave biologists. The San Antonio Zoo Department of Conservation and Research (SAZ DOCR) maintains a captive colony of this species, including two individuals that have been in captivity for over twenty years. Members of the Blindcat Working Group (a multinational team of researchers) are exploring the geographic distribution and population genetics of this species using eDNA, Next Generation sequencing, and boots-on-the-ground field efforts.

A babyeater cichlid, Lipochromis melanopterus, at the San Antonio Zoo.

Many cichlids like this are mouth brooders. This species is famous for going up to the mouth brooding mother of another species, then scaring that mother into spitting out her babies so the babyeater can consume them.
