Sense Organs
Objective: Explain how animals use their sense organs in particular situations.
Tongue: Animals use their tongues in many different ways and for many different
uses. They may also have more than one tongue. Insects such as bees have tongues
on their feet, antennae and mouth. They can taste things using any of them. Fishes
have tongues on their fins, tails and mouth. Some animals use their tongue to keep
themselves clean (cats lick themselves), and others use it to capture food. Frogs
often catch flies with their tongue.
The Skin: Animals use their skin, but not just for touching things. Their skin has a
variety of uses. Some animals use their skin to breathe. For example, frogs take in
air through their moist skin. Other animals use their skin as a way to protect
themselves. Lizards can change their colour to match their surroundings, making it
hard for other animals to see them. Other animals use their skin to obtain food
and for finding a mate.
The Nose: Animals rely more on their sense of smell than humans. They also use it
for different purposes. Some animals use it to track down a prey or even to find a
mate. They may also use their sense of smell to protect them from other animals. In
other animals, the sense of smell is used to recognize their relatives and to find
food. Moreover, animals may use the sense of smell to communicate with each
other.
