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

有些动物，比如锄，因为环境压力而吞食自己同类。

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

锄蜍钻进沙漠土壤，进入休眠状态，然后被闹钟唤醒。

The spadefoot toad is far from the only animal to eat members of its own species as a normal part of its life cycle.

锄远不唯一把吞食自己同类以生存作为正常生命周期一部分动物。
