What is an echidna?
An echidna is a spiky, egg-laying mammal from Australia and New Guinea. It looks a bit like a hedgehog with a long snout. Echidnas eat ants, termites, and other small moving bugs.
How it finds moving bugs — step by step
- Sniffing and listening: The echidna uses its nose to sniff out where bugs might be and its ears to hear tiny sounds in the ground or inside logs.
- Sensing tiny movements and electricity: The tip of its snout has special sensors that can feel tiny movements and even detect weak electrical signals made by insect muscles. These sensors help the echidna find bugs that are hidden.
- Digging with strong claws: When it finds a good spot, the echidna digs into soil, leaf litter, or rotting wood with its sharp claws to reach the insects.
- Flicking a sticky tongue: The echidna has a long, sticky tongue that it flicks in and out very fast. Bugs stick to the tongue and are pulled into the mouth. Echidnas do not have teeth; they press food against the roof of their mouth to break it up.
- Eating many tiny bugs quickly: By digging and flicking its tongue over and over, an echidna can eat hundreds or thousands of tiny insects in a short time.
Quick facts
- Echidnas and platypuses are the only egg-laying mammals.
- The special sensors on their snout let echidnas find food even when bugs are hidden under soil or wood.
- They are excellent at finding and eating small, moving creatures even though they move slowly.
