Species and Class

Biology Summaries

Here is a brief summary classification table of all currently living things -
about one million animal species, and about one-half million plant species.


Biology Facts -
The vast majority of all living animal species are insects.
There are way more beetle species than you can shake a stick at - hundreds of thousands.
Greater than 99% of all species that have ever lived have been extinct for millions of years.
