Learn about blob and their invertebrate friends.
Meet Blob. He is an invertebrate.
This means that he has no backbone
…or spinal column.
Blob is a very simple invertebrate, just like worms or jellyfish.
Over 96% of all the animal species on Earth are invertebrate.
They can be tiny like an insect or huge like the giant squid.
Invertebrates
Animals can be classified as either vertebrates or invertebrates.
Invertebrates are animals that don't have a backbone. Some have soft bodies, like worms, slugs and jellyfish. Other invertebrates, like insects, spiders and crustaceans, have a hard outer casing called an exoskeleton. This protects their body a bit like a suit of armour.
Vertebrates have a backbone inside their body. They include mammals, birds, fish, amphibians and reptiles.
