About amphibians

(English below)


兩棲動物是需要水或潮濕環境來生存的小型脊椎動物這一群物種包括青蛙、蟾蜍、蠑螈和水螈。兩棲動物可以透過薄的皮膚呼吸和吸收水分。兩棲動物的皮膚上還擁有特殊的腺體,可以產生有用的蛋白質。一些腺體負責將水分、氧氣和二氧化碳運送到動物內或排出體外。其他腺體則可以對抗細菌或真菌感染。而在每個物種中至少有一種腺體是用於防禦的。為了警告潛在的捕食者,最有毒的兩棲動物也是顏色最鮮艷的。例如,箭毒蛙的皮膚上含有箭毒。而在每個物種中至少有一種腺體是用於防禦的。為了警告潛在的捕食者,最有毒的兩棲動物也是顏色最鮮艷的。例如,箭毒蛙的皮膚上含有箭毒。兩棲動物的另一個特殊特徵是它們的卵-幼蟲-成年生活週期。幼年是水生的,可以自由遊動,青蛙和蟾蜍在這個階段被稱為蝌蚪。在一定的大小時,幼體會發育出四肢和肺部。有些還會失去尾巴。最終,它們轉變成年時會跳躍或爬出水面,並在陸地上度過其餘的生命。這個過程被稱為變態。與爬行動物一樣,兩棲動物是冷血的。由於他們特殊的皮膚,它們需要非常特定的生活條件。過多的陽光可能會損害他們的細胞。過多的風可能會使他們的皮膚乾燥,使動物脫水。因此,當其棲息地受到幹擾或受到像除草劑等化學品的污染時,兩棲動物往往是首先死亡的物種。這也是超過一半的蛙類物種瀕臨絕種的主要原因。



About Amphibians

Amphibians are small vertebrates that need water, or a moist environment, to survive.The species in this group include frogs, toads, salamanders, and newts. All can breathe and absorb water through their very thin skin.Amphibians also have special skin glands that produce useful proteins. Some transport water, oxygen, and carbon dioxide either into or out of the animal. Others fight bacteria or fungal infections. And at least one—in each species—is used for defense. To warn potential predators, the most toxic amphibians are also the most brightly colored. Curare [kyoo-RAW-ree], for example, is found on the skin of colorful poison dart frogs. Another special feature of most amphibians is their egg-larva-adult life cycle. The larvae are aquatic and free-swimming—frogs and toads at this stage are called tadpoles. At a certain size, the young develop limbs and lungs. Some also lose their tails. Eventually, they hop or climb out of the water as adults, and spend the rest of their lives on land. This process is known as metamorphosis. Like reptiles, amphibians are cold-blooded. Because of their special skin, they require very specific living conditions. Too much sun can damage their cells. Too much wind can dry their skin and dehydrate the animal. As a result, amphibians are the first to die off when their habitats are disturbed or contaminated with chemicals like weed killers. This is the main reason over half of all frog species are in danger of extinction.
