Four species are categorized as endangered by the International Union for Conservation of Nature: the Barton Springs salamander, the Texas blind salamander, the black-spotted newt, and the Houston toad. Furthermore, Texas law protects several native amphibians, designating eleven species as threatened within the state and four others as endangered.
The coloration of the red salamander has been hypothesized to mimic that of the red eft stage of the eastern newt (Notophythalmus viridescens) which emits a powerful neurotoxin in their skin. [29] This phenomenon is known as the Mullerian Mimicry Complex. [30]
Crested newt females usually lay around 200 eggs per season, while the marbled newt (T. marmoratus) can lay up to 400. Triturus embryos are usually light-coloured, 1.8–2 mm in diameter with a 6 mm jelly capsule, which distinguishes them from eggs of other co-existing newt species that are smaller and darker-coloured.
Each egg has a large yolk sac and the larva feeds on this while it develops inside the egg, emerging fully formed as a juvenile salamander. The female salamander often broods the eggs. In the genus Ensatinas , the female has been observed to coil around them and press her throat area against them, effectively massaging them with a mucous secretion.
