Range and habitat
Incilius cristatus (formerly Bufo cristatus), the large-crested toad, is an endangered species of true toad that is endemic to cloud forests in the central Sierra Madre Oriental in Puebla and Veracruz, Mexico. The reasons for its decline are habitat loss and pollution, and there are no recent records from Veracruz.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Breeding
Calling males and egg sites define most frog field work. A species known from one ridge is as narrow as it sounds.
Eggs and damp skin make amphibians quick to vanish from a drained wetland or a forest stripped of litter.
In crisis
Once feared extinct, it has recently been rediscovered at two sites in Puebla where it is uncommon.
Chytrid fungus, collection, and wet-forest loss are the usual pressures on frogs with a high threat category.
