Go back far enough in our history–maybe about 650 million years–and you come to a time when our ancestors were still invertebrates. That is, they had no skulls, teeth, or other bones. They ...

The total number of invertebrate species could be 5, 10, or even 30 million, com- pared to just 60,000 vertebrates. One reason for the success of invertebrates is how quickly they reproduce.

Revise and learn what type of animal a vertebrate is. Find out what the difference is between an invertebrate and a vertebrate in this KS2 biology Bitesize guide.

Our earliest invertebrate ancestors did not have brains. Yet, over hundreds of millions of years, we and other vertebrates have developed amazingly complicated mental machinery.

Logging slashes the abundance of invertebrates like ants and earthworms but new research shows vertebrates can take up their roles in the ecosystem.

Not unexpectedly, the field of invertebrate immunology therefore lags far behind that of vertebrate immunology, although it does have a long history and is rapidly developing 1, 2, 3, 4.

Animals can be classified as either vertebrates or invertebrates. Vertebrates are animals that have a backbone inside their body. The major groups include fish, amphibians, reptiles, birds and ...
