Some species, like the spadefoot toad, cannibalize in response to environmental pressures.

有动物，比如锄足蟾，是因为环境压力而吞食自己的同类。

Where spadefoot toads burrow into the desert soil and go dormant before waking up to an alarm clock of raindrops.

锄蟾蜍钻进沙漠的土壤，进入休眠状态，然后被雨滴的闹钟唤醒。

锄足蟾远不是唯一把吞食自己同类以生存作为正常生命周期一部分的动物。
