The South China giant salamander (Andrias sligoi), can reach a length of 1.8 m (5.9 ft). [1] The Japanese giant salamander (Andrias japonicus) reaches up to 1.44 m (4.7 ft) in length, feeds at night on fish and crustaceans, and has been known to live for more than 50 years in captivity. [2]
Salamanders range in size from the minute salamanders, with a total length of 27 mm (1 + 1 ⁄ 8 in), including the tail, to the Chinese giant salamander which reaches 1.8 m (6 ft) and weighs up to 65 kg (145 lb).
The salamanders prefer to live in streams of small width (on average, 6.39 m or 21 ft across), quick flow, and little depth (on average, 1.07 m or 3 ft 6 in deep). [33] Water temperature varies depending on season, with typical range at low elevation sites being from 10 to 25 °C (50 to 77 °F) and at high elevation sites from 3 to 20 °C (37 ...
Japanese giant salamanders in Tottori Prefecture, Japan, showing notable color variation among individuals within the same population. Andrias japonicus skull. The Japanese giant salamander (Andrias japonicus) is a species of fully aquatic giant salamander endemic to Japan, occurring across the western portion of the main island of Honshu, with smaller populations present on Shikoku and in ...
Male marbled salamanders have also been shown to have a higher survivorship than females. [9] Marbled Salamanders in the northern portions of their range can also go into a state of torpor to survive the cold months. [10] Adults spend most of their time in their burrows or under logs, as is the case with most mole salamanders.
Tiger salamander (Ambystoma tigrinum) Ambystoma tigrinum Biofluorescence in Ambystoma tigrinum. These salamanders usually grow to a length of 6–8 in (15–20 cm) with a lifespan of around 12–15 years. [5] They are characterized by having markings varying in color on the back of their head, body, and tail. [6]
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 ...
Phylogenetic analyses have however shown that species in the Salamandridae traditionally called newts do form a monophyletic group. [1] [16] [17] Other, more distantly related salamander families also contain fully or in part aquatic species, such as the mole salamanders, the Proteidae, or the Sirenidae.
