Hint: Mammals, birds, fish, reptiles, and amphibians are vertebrates.
Vertebrates and invertebrates are both groups of animals.
A vertebrate has a backbone. The backbone is made of many bones in an animal's back. A vertebrate's backbone helps connect the different parts of its body. In the drawings below, each vertebrate's backbone is colored orange.
An invertebrate does not have a backbone. In fact, invertebrates do not have any bones! Some invertebrates have an outer cover on their body called an exoskeleton. Other invertebrates have a soft body.
Like other spiders, an orb weaver is an invertebrate. It does not have a backbone. It has an exoskeleton.
A fly is an insect. Like other insects, a fly is an invertebrate. It does not have a backbone. It has an exoskeleton.
An earthworm is a worm. Like other worms, an earthworm is an invertebrate. It does not have a backbone. It has a soft body.
