Insectivores

ButterflyPie chart - 22% InsectivoresThe amazing abundance and diversity of the insects is mirrored by the large number of animals that use them for food. 

Many of the species found at Naracoorte survived on a diet composed mainly of insects and other invertebrates.

Interestingly, the majority of insectivores that lived at Naracoorte thousands of years ago are still to be found in the area today.

These animals include frogs and tortoises, lizards, birds, small marsupials, rodents and bats.

Bats are highly adapted insect eaters and catch nocturnal, flying insects using echolocation for hunting.

Other insectivores make use of a range of insects and other invertebrates.

Insectivorous mammals have sharp teeth for piercing and crushing the exoskeleton of insects.

Some insectivores are highly specialised such as the ant-eating Echidna Tachyglossus aculeatus which has a long snout and tongue for collecting ants and termites.

In the woodlands of ancient Naracoorte, the Giant Long-beaked Echidna Megalibgwilia ramsayi foraged for grubs and worms.

The long snout is made up of a hollow tube, through which the tongue extended to grasp the prey.
