Invertebrates

Invertebrates are all animals that do not have a backbone.

The most common group is insects but also includes spiders, worms and shellfish.

Cone-shaped pits are commonly seen in sandy soil throughout the NT. These traps are made by an unusual predator called the ant-lion.

Not all cockroaches are pests, there are native ones too.

Australia has hundreds of different species of grasshoppers that come in all shapes, sizes and colours.

Green ants are common in the trees of northern Australia.

This aggressive insect is one of natures most skillful builders.

Hermit crabs are unusual because they use sea snail shells for their homes - the ultimate recyclers.

At least two species of mouse spiders are found in the NT and they can grow to the size of a 50 cent coin.

Sometimes condemned as pests, termites are hard workers that are vital to the Australian bush.
