Caddis flies are a type of insect. The young nymphs build a home out of small stones, twigs, leaves and sand. This makes them appear camouflaged against their background.
An animal is camouflaged when it is the same colours as the background it lives on.
Cassowaries are birds that can grow up to 2 metres tall! They eat juicy fruits that grow on rainforest trees. Their throats are so big they can eat fruits whole! The seeds come out in the droppings and grow into new rainforest plants. Cassowaries are endangered.
Catkins are the flowers that appear on some trees in the spring. You can find them on Pussy Willow and Hazelnut trees
Spiders spin cobwebs by making their own silk. These webs are very strong. They trap insects that fly into them. When an insect has been caught, the spider wraps it in more silk until it is ready to eat it!
Baby swans are called cygnets. They have soft grey feathers and grey beaks. It takes a year for the cygnets to grow new white feathers like an adult swan.
