Ambystomatidae is a family of salamanders belonging to the Suborder Salamandroidea in the class Amphibia. It contains two genera, Ambystoma (the mole salamanders) and Dicamptodon (the Pacific giant salamanders).

Rhyacosiredon was previously considered a separate genus within the family Ambystomatidae. However, cladistic analysis of the mole salamanders found the existence of Rhyacosiredon makes Ambystoma paraphyletic , since the species are more closely related to some Ambystoma species than those species are to others in Ambystoma .

鈍口螈屬 （學名： Ambystoma）是多種分布於 北美 的 蠑螈。 體型中等。 有明顯的肋骨間溝。 尾部側向壓縮。 頭部寬大、眼小。 不好動。 通常棲息於地底。 由於 棲息地的破壞，多個物種均為 瀕危物種。 本属包括以下物种： [1] 墨西哥钝口螈 Ambystoma mexicanum (Shaw and Nodder, 1798) :又名美西钝口螈。 ^ Ambystoma Tschudi, 1838. GBIF. [2023-06-08]. （原始内容 存档 …

钝口螈中的有些种类终生保持幼体特征而生活于水中，其中最著名的是仅分布于墨西哥的一个湖泊中的 墨西哥钝口螈 Ambystoma mexicanum或称 美西螈，基本上终生保持幼态，只有极少数完成变态，而主要分布于美国的 虎纹钝口螈 Ambystoma tigrinum在东部低地很短时间就完成变态而在西部高山区则保持幼体形态，虎纹钝口螈也是体型最大的陆栖蝾螈之一，身长最大可达到40厘米。 列入《濒危野生动植物种国际贸易公约附录Ⅰ、附录Ⅱ和附录Ⅲ》。 [1] 钝口螈 …

Am­bystom­atids are stout-bod­ied sala­man­ders of mod­er­ate size (10-30 cm adult length). Their tails are thick, their limbs ro­bust, their skin smooth and shiny, and many have bright color pat­terns. They ex­hibit the most de­rived pat­tern of spinal nerves known in sala­man­ders, and their diploid num­ber is 28.

鈍口螈 （学名： Ambystoma dumerilii），是一種 幼態延續 的 蠑螈。 因其生活地点也叫 帕茨夸羅湖蝾螈 （英語： Lake Patzcuaro salamander），当地名称 Achoque 或 西班牙語： Ajolote de Pátzcuaro） 鈍口螈分佈在 墨西哥 米卻肯州 的 帕茨夸羅湖。 帕茨夸羅湖位於高 海拔，是很多 鈍口螈屬 的家園。 有指在 克雷塔羅州 聖喬安德爾里奥 的西北內陸有發現鈍口螈的 亞種，但卻因牠們是完全水生而存疑。 鈍口螈整生也會保有其 幼體 特徵，故成體有很長及多絲的外 鰓 、 牙 …

It belongs to a family of lungless salamanders (Plethodontidae) that breathe only through their moist skin. Although this may seem to be a handicap to their survival, there are more species in this family than in any other family of salamander.

Characteristics: Ambystomatids are heavy-bodied, heavy-tailed salamanders with four short, well-developed limbs (Fig. 16.10). Adult size ranges from 80 to 550 mm, usually >160 mm TL. The lower jaw has fused angular and prearticular bones; the upper jaw has paired premaxillae and maxillae, and the lacrimal is absent.
