- Food is often in short supply
食物总是很紧缺 - and troglodytes like the crab
像螃蟹这样的穴居动物 - have to survive on whatever washes into the cave from outside.
必须得吃任何从外边冲进洞内的东西 - The salamander might not encounter food for several months,
童态河溪螈可能 已有几个月没有吃东西了 - so when something does come along
所以只要眼前有食物出现 - it can't afford to miss it.
它绝对不会放过 - It's astonishing that these extraordinary cave dwellers manage to survive at all.
这些奇异的洞栖生物能如此成功地生存 的确令人称奇
The salamander might not encounter food for several months, 童态河溪螈可能 已有几个月没有吃东西了
