tardigrade

Also known as moss piglets, moss piglet, water bears, water bear, Tardigrada, tardigrades

Tardigrades (), also known as water bears or moss piglets, are a phylum of eight-legged segmented micro-animals. They were first described by the German zoologist Johann August Ephraim Goeze in 1773, who called them ' . In 1776, the Italian biologist Lazzaro Spallanzani named them Tardigrada', which means 'slow walkers'.

AI overview

Tardigrades, also known as water bears or moss piglets, are tiny eight-legged creatures that belong to their own phylum of micro-animals. These microscopic organisms were first identified in 1773 and named "Tardigrada" (meaning "slow walkers") in 1776, establishing them as a recognized group in the animal kingdom.

缓步动物门（学名：Tardigrata）是俗称水熊虫的一类小型动物，主要生活在淡水的沉渣、潮湿土壤以及苔藓植物的水膜中，少数种类生活在海水的潮间带。有記錄的大约有750余种，其中许多种是世界性分布的。在喜马拉雅山脉（海拔6000米以上）或深海（海拔-4000米以下）都可以找到它們的蹤影。直至今日，人们对缓步动物在动物分类中的位置、形态学、生活方式、组织学以及其隐生性的研究兴趣有增无减。緩步動物也是第一種已知可以在太空中生存的動物。

Tardigrades live in diverse regions of Earth's biospheremountaintops, the deep sea, tropical rainforests, and the Antarctic. They are among the most resilient animals known, with individual species able to survive severe conditions, such as exposure to extreme temperatures, extreme pressures (both high and low), air deprivation, radiation, dehydration, and starvation – that would quickly kill most other forms of life. Tardigrades have survived exposure to outer space.
