Structural adaptations
Spikes
Echidnas have spines covering their bodies. These spikes are sharp, and they help the echidna scare off predators.
Tongues
Echidnas have long, quick tongues that help them catch food.
Fur
Depending on where the echidna is, fur density varies in order to allow the echidna to stay warm. This mainly occurs in Tasmania, where echidna fur is generally denser than other parts of Australia.
