中文百科
箭毒蛙![]() ![]() ![]() 箭毒蛙,即箭毒蛙科(Dendrobatidae),又名树棘蛙科或丛蛙科,是细小及白天活动的青蛙。牠们是中美洲及南美洲的原住民,而当地部族将牠们身上的毒素涂在箭上,故得此名。此科下有超过175个物种,但只有3种的毒素,毒素的来源是捕食当地的某种蚂蚁和虱子转化而来,所以人工驯养会变得没有毒性,购买观赏蛙时应该避免野生捕获的剧毒个体。此科下身体最多色彩的是箭毒蛙属,而毒素最剧烈的是叶毒蛙属的金色箭毒蛙。
英语百科
Poison dart frog 箭毒蛙![]() ![]() ![]() Poison dart frog (also known as dart-poison frog, poison frog or formerly known as poison arrow frog) is the common name of a group of frogs in the family Dendrobatidae which are native to tropical Central and South America. These species are diurnal and often have brightly colored bodies. This bright coloration is correlated with the toxicity of the brightly colored species, making these species aposematic. Some species of the Dendrobatidae family exhibit extremely bright coloration along with high toxicity, while others have cryptic coloration with minimal to no amount of observed toxicity. The species that have great toxicity, derive this from their diet of ants, mites and termites. Other species however, that exhibit cryptic coloration and low to no amounts of toxicity, eat a much larger variety of prey. Many species of this family are threatened due to human infrastructure encroaching the places they inhabit. |
