The Prey is No Pushover

-

Prey which is on the menus of countless predators must use drastic methods to produce offspring in waterhole jungles.

EXPLODING NUMBERS

Copepods are one of the species, whose offspring hatches at the same time in a brief population explosion. The loads of prey confuse predators, ensuring that as many individual­s as possible survive to breed new generation­s.

HIGHER SPEED

Apart from hiding, they prey’s only way of surviving is to be faster than the predators. Some insect larvae can shoot water out of their anuses with such force that they speed through the water.

STRONGER ARMOUR

Water fleas, of which most lakes include millions, can immediatel­y adapt, if the hunt for them intensifie­s. In a few days, they will start having offspring with longer spikes, making it harder for predators to swallow them.
