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.
The California slender salamander (Batrachoseps attenuatus) is a lungless salamander [2] that is found primarily in coastal mountain areas of Northern California, United States as well as in a limited part of the western foothills of the Sierra Nevada, California, in patches of the northern Central Valley of California, and in extreme southwestern Oregon.
Many salamanders do not use vocalisations, [70] and in most species the sexes look alike, so they use olfactory and tactile cues to identify potential mates, and sexual selection occurs. Pheromones play an important part in the process and may be produced by the abdominal gland in males and by the cloacal glands and skin in both sexes.
While Batrachoseps major is a small salamander, it is larger than most other Batrachoseps slender salamanders. Adults are 3.2–5.9 centimetres (1.3–2.3 in) in length and have 17-21 costal grooves. [3] Like other Batrachoseps, B. major has only four toes on its hind feet.
Aquatic salamander teeth are used to hinder escape of the prey from the salamander; they do not have a crushing function. [17] This aids the salamander when feeding. When the salamander performs the "suck and gape" feeding style, the prey is pulled into the mouth, and the teeth function to hold the prey inside the mouth and prevent the prey ...
Spotted salamanders do produce poisonous skin secretions, which allow them to taste bad to predators. For a human, these skin secretions are more irritating and would not kill an adult or even a ...
These salamanders are slender, with a wide nose and distinctive long toes, and range in size from 11 to 18 cm (4.3 to 7.1 in). Like other mole salamanders, the Jefferson salamander burrows; they have well-developed lungs suited for this purpose. Nocturnal by nature, they can be spotted by day during the mating season. Breeding occurs in early ...
