Houston Toad
Anaxyrus houstonensis (Sanders, 1953)

Current SSAR Comments:
This species hybridizes with A. woodhousii (as well as with Incilius nebulifer); both hybrid and non-hybrid individuals can be difficult to identify with respect to A. woodhousii. Taxonomists and conservationists working on this endangered species consistently recognize it as distinct. Recent work confirmed a close historical relationship with A. americanus and supported recognition as a species (Sirsi et al., 2024, Science Reports, 14: 3306).
