Range

Widely distributed across Africa (Seychelles), Asia (Japan), Europe (5 countries), North America (7 countries), Oceania and the Pacific (Marshall Islands, Vanuatu), and South America (5 countries). Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

川南疣螈

The Chuannan Crocodile Newt (Tylototriton pseudoverrucosus) is an Endangered salamander in the family Salamandridae, endemic to southern Sichuan and possibly adjacent regions of southwestern China. The genus Tylototriton, commonly called crocodile newts or knobby newts, is characterized by robust bodies with raised dorsolateral glands, prominent cranial ridges, and bright warning coloration — typically contrasting orange or yellow markings on a dark body — that signal the presence of potent tetrodotoxin-related neurotoxins in the skin. T. pseudoverrucosus is closely related to T. verrucosus and was described as a distinct species based on morphological and molecular differences. The species inhabits humid subtropical forest and associated streams at mid to high elevations, breeding in small water bodies and stagnant pools in forested areas. Its Endangered status reflects the ongoing destruction and fragmentation of subtropical forest habitat in southwestern China from logging, agricultural conversion, and urban expansion. The international trade in wild-caught Tylototriton species for the pet trade also poses a significant threat to wild populations. Population monitoring and habitat protection in Sichuan are priorities for conservation of this species.
