Predator Hunting Strategies
Understand that predators have evolved hunting strategies — wolves hunt in packs, chameleons use their long tongues, spiders build webs, crocodiles ambush at water's edge — and prey animals have evolved defences — porcupine spines, skunk spray, poison dart frog toxins, zebra stripes confusing predators, playing dead
What a learner can do afterwards
- Describes at least 3 predator hunting strategies with examples
- Describes at least 3 prey defence mechanisms with examples
- Understands the concept of an 'arms race' between predators and prey
The lesson
You already know that camouflage helps animals hide. But hiding is not the only trick out there. Predators have hunting strategies to catch food, and prey animals have defences to stay alive, and both keep getting better over time.
Wolves hunt in packs. They work together to chase and surround an animal that would be too strong for one wolf alone. A chameleon does the opposite: it waits alone and flicks out its long, sticky tongue faster than you can blink. A crocodile floats so still near the water's edge that a thirsty animal does not notice it, until it strikes.
A porcupine has sharp spines that poke any mouth that bites it. A skunk sprays a stinky liquid that stings a predator's eyes and nose. A poison dart frog's skin makes a poison, called a toxin, so strong that predators learn to leave its bright colours alone. When zebras run together as a herd, their stripes blur together, making it hard for a lion to lock onto just one zebra. Some animals, like the opossum, simply flop over and lie still as if dead, since many predators lose interest in food that is not moving.
Predators and prey are stuck in a kind of race. If prey get better at escaping, only the sharpest hunters catch enough food to survive and have young. If predators get better at hunting, only the best-defended prey survive and have young. Over many, many years, this back-and-forth is called an arms race.
Predators hunt with teamwork, speed, traps, and ambush, prey defend with spines, spray, poison, patterns, and playing dead, and both sides keep adapting to each other.
