The association of the salamander with fire appeared first in Antiquity with Aristotle (History of Animals 5, 17) and with Pliny the Elder writing in his Natural History (10, 86) that "A salamander is so cold that it puts out fire on contact. It vomits from its mouth a milky liquid; if this liquid touches any part of the human body, it causes ...
Small-mouth salamanders are nocturnal, often subterranean, preferring moist habitats near permanent bodies of water. Breeding occurs in the spring, with groups of salamanders congregating near the water. Females can lay up to 700 eggs, which they attach in small clumps of up to 30 eggs at a time, to rocks or vegetation under the water.
[15] [16] The common mudpuppy never leaves its aquatic environment and therefore does not undergo morphogenesis; however, many salamanders do and develop differentiated teeth. [17] 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.
This large salamander grows to a total length (including tail) of 29–57 cm (11–22 in) over a lifespan of 30 years. [6] The Ozark hellbender is a nocturnal predator that hides under large flat rocks and primarily consumes crayfish and small fish.
Both males and females grow to an adult length of 24 to 40 cm (9.4 to 15.7 in) from snout to vent, with a total length of 30 to 74 cm (12 to 29 in), making them the fourth-largest aquatic salamander species in the world (after the South China giant salamander, the Chinese giant salamander and the Japanese giant salamander, respectively) and the ...
Cryptobranchids are large and predominantly nocturnal salamanders that can reach a length of 1.8 m (5.9 ft), though most are considerably smaller today. [1] Despite being aquatic, they are poor swimmers and mostly just walk on the bottom.
Salamandridae is a family of salamanders consisting of true salamanders and newts. Salamandrids are distinguished from other salamanders by the lack of rib or costal grooves along the sides of their bodies and by their rough skin. Their skin is very granular because of the number of poison glands. They also lack nasolabial grooves.
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.
