Invertebrates
Last week we looked at vertebrates, that is animals which have a backbone. This week, our focus will be on invertebrates ( in + vertebrates). You will remember from your literacy lessons that the prefix in- means no, or not. In this case, it means animals without a backbone. In our immediate environment, we normally see animals with a backbone; humans, cats, dogs, squirrels, birds. However, scientists have estimated that around 95% of all animals are invertebrates. Some of those include animals that haven't been discovered yet!
Have a look at some recently discovered animals:
