A correlation exists between the toxicity of Californian salamander species and diurnal habits: relatively harmless species like the California slender salamander (Batrachoseps attenuatus) are nocturnal and are eaten by snakes, while the California newt has many large poison glands in its skin, is diurnal, and is avoided by snakes.
Crepuscular, a classification of animals that are active primarily during twilight, making them similar to nocturnal animals. Diurnality, plant or animal behavior characterized by activity during the day and sleeping at night. Cathemeral, a classification of organisms with sporadic and random intervals of activity during the day or night.

North Island brown kiwi, Apteryx mantelli [1] Black-crowned night heron, Nycticorax nycticorax [1] Short-eared owl, Asio flammeus [1] Long-eared owl, Asio otus [1]
These salamanders do move slowly, which could increase their risk of being caught. [28] Generally, predators of the broad category of toxic Salamandra species can include birds, rats and snakes, as well as other, larger carnivorous mammals like raccoons, minks, wild boars and foxes. [10] One notable predator of S. atra is young snakes. [28]
Desmognathus fuscus is a species of amphibian in the family Plethodontidae (lungless salamanders). [2] [3] The species is commonly called the dusky salamander or northern dusky salamander to distinguish it from populations in the southern United States which form several distinct species, the southern dusky salamanders (D. auriculatus, D. valentinei). [3]
The western slimy salamander (Plethodon albagula), also known as the whitethroat slimy salamander or white-throated slimy salamander, is a species of salamander.It is endemic to the United States of America and found in two disjunct populations, one from Missouri to Oklahoma, and Arkansas, and another in south-central Texas.
It is believed that predators of the Mount Lyell salamanders include birds, snakes, and mammals that typically feed on similar species. [5] The most common prey of the salamander include small invertebrates, such as centipedes, spiders, termites and other organisms commonly found under cover objects like rocks and leaves. [6]
Plethodontidae, or lungless salamanders, are a family of salamanders. [ 1 ] [ 2 ] With over 500 species, lungless salamanders are by far the largest family of salamanders in terms of their diversity. Most species are native to the Western Hemisphere , from British Columbia to Brazil.
