I’m going to become a wildlife investigator!
Great job learning new science words!
Acheetah has adaptations that make it a very successful predator. It can run at 112 km/h, which is more than four times faster than a human running at top speed. A cheetah has a streamlined shape to help it run this fast. Its eyes are in the front of its head so that it can judge distance well. When the cheetah is crouched low, watching its prey, it is well camouflaged because its colours blend in with the dry grass environment.
The springbok is the prey. Springbok stay together in large groups. This is their most important adaptation to avoid being caught and eaten. But there is often a springbok that gets left behind the group or which cannot run so fast. These are the animals that the predator hunts and kills.
All predators have adaptations to help them catch their prey. All prey animals have adaptations to avoid being caught.
Examples of adaptations that predators have are:
1. Which adaptation from the list on the previous page do you think a spider has to make it a successful predator?
Here are some more examples. The chameleon can shoot its tongue out so far and so fast that the beetle does not stand a chance. Can you spot the chameleon in the right-hand photograph? Chameleons use camouflage to hide from their prey.
2. What other adaptations does the snake have that you can see in the photograph?
3. What other adaptations can you see on the photograph of an eagle that will help the eagle to catch its prey?
4. What other adaptations do the dogs in the photograph have which will help them to catch their prey?
Question: What adaptations do different predators have that help them to catch their prey?

Follow-up Questions:
Great work thinking like a scientist and explaining how different predators are adapted to catch their prey.
Prey animals need to either defend themselves in some way or attack their predator.
Hiding from a predator is one way of defence. You saw how a chameleon uses camouflage to blend in with its surroundings so that it can catch its prey. But it also does the same thing to hide from its predators.
Other animals use camouflage to hide. Look how well this moth and this fish blend into their surroundings!
Many animals stay in a group for safety. The grass-eaters such as zebras, antelopes and wildebeest are prey for predators such as lions and cheetahs. They stay in large groups. Sometimes animals in the group have ‘look-out duty’ and have to warn the rest of the group with a special sound if they see a predator.
Fish often stay in big groups to defend themselves from bigger fish that eat them. Look at all these sardines defending themselves from dolphins.
Bees live in big groups in a hive. Bees use smell as a signal. If a predator comes close to the hive, the guard bees give off a special smell. They beat their wings to spread the smell. Other bees join the guard bees to defend the hive.
Some prey try to frighten their predators away with weapons such as stings, horns and quills.
Bees and wasps sting the predator. Some ants spray the predator with acid.
Many animals such as rhinos, antelope, gemsbok and buffalos have big, pointed horns. They can use their horns as a weapon if a predator attacks them.
Aporcupine spreads out and rattles its quills to make it look and sound more dangerous. If the predator does not run away, the porcupine charges backwards and stabs the predator with its quills. The quills often break off, leaving the predator full of painful quills.
Tortoises and turtles are very slow movers. But they have a hard shell. When a predator approaches they pull their head in under their shell for protection.
Many prey animals have eyes at the sides of their heads. This allows them to see a predator on both sides of them. Lizards, antelopes and fish are examples.
Being fast is a good way to escape from your enemy. For example, antelopes can run fast when a lion or a cheetah is chasing them.
An octopus has eight legs and eyes on each side of its head. When an octopus sees a predator, it shoots out a cloud of ink to confuse it. Then it swims away very fast, leaving its predator surrounded by ink.
