Read the passage 2 The Truth about Spiders Spiders may look like insects, but are very different from them. One difference between a spider and an insect is that a spider’s body is divided into two parts, the head and the abdomen. Insects have a third part, called the thorax. Additionally, spiders have eight legs, while insects have only six. All spiders are carnivores. They eat insects or other small creatures. They use their fangs to inject their prey with poison. All spiders also have spinnerets that are used to produce silk. However, not all spiders make webs. There are nearly 40000 types of spiders living in all parts of the world. One of the largest spiders is the goliath spider, which lives in South America. One goliath spider measured more than 27 centimetres across. These spiders primarily live on birds. Like most spiders, they are not generally considered dangerous to humans. Post reading Answer the following questions: Questions for comprehension: 1.
