1. Spiders are known for making webs but did you know that not all spiders make them?

In fact, only around half of spiders use webs to catch prey.

2. The Jumping Spider is so quick it can actually pounce on its prey.

3. Not all bird eggs are white or brown. Wild eggs are often an array of colours including blue, green and red. The strength of the colour can be completely different, creating amazing patterns.

6. Giant African land snails have both male and female reproductive organs. Although snails mate with each other, when isolated they can reproduce by themselves.

7. Giant millipedes do not have a million legs. The giant African millipede only has around 300 to 400. But it is still the largest of the 10,000 species of millipede.

8. Snakes can not chew food, meaning they have to swallow it whole. A snake has even been filmed attempting to swallow a whole cow.
