FAQ
Frequently Asked Questions
No, they are not closely related. Their spiny appearance is an example of convergent evolution. Echidnas are monotremes (egg-laying mammals), while hedgehogs are placental mammals.
Echidnas are insectivores. They use their strong claws to break open ant and termite nests and their long, sticky tongues to catch the insects.
No, they are shy, solitary animals. When threatened, they curl into a ball or dig straight down, presenting only their sharp spines to a predator.
They are completely unrelated homonyms. The animal's name was chosen in the 19th century by naturalists, likely due to its perceived 'monstrous' or unusual nature, echoing the Greek monster.
