No-one knows for definite because we are always discovering more or a species becomes extinct.There could be more than thousands.There are many types of animals on Earth. I am not positive on how many, but there are vertebrates and invertabrates. Invertebrates are animals without a backbone. For an example, snakes or worms. Vertebrates are the opposite. They are animals with a backbone. For an example, dogs, cats and birds. Most of the animals on Earth are vertebrates.
All vertebrates are in the phylum Chordata.
