"More than 95% of Australian animals are invertebrates (animals without
backbones – spiders, snails, insects, crabs, worms and others). There are at
least 300,000 species of invertebrate in Australia. Of these, two-thirds are
unknown to western science.

This means there are huge gaps in our knowledge of Australia’s invertebrates.
Our new study, published today in the journal Cambridge Prisms: Extinction,
indicates there has been a catastrophic under-recording of Australia’s species
extinctions.

Our best estimate is that 9,111 invertebrate species have become extinct in
Australia since 1788. This dwarfs the current official estimate of the total
number of extinctions across all plant and animal species in Australia: 100.

The extinction of so many invertebrate species is not an arcane concern for
those few people who care about bugs. Invertebrates are the building blocks of
almost all ecological systems.

Loss of invertebrates will destabilise those systems. It will negatively impact
the resources we depend upon, like pollination, cycling of nutrients into the
soil, clean air and waterways."
