How an echidna's nose finds moving bugs
Echidnas are small, spiny animals that eat ants, termites and other little creatures. Their nose (snout) is special — it helps them find bugs even when the bugs are hiding.
- Sniffing and tasting: The echidna smells and tastes the ground. This helps it know where lots of ants or termites are living.
- Feeling tiny movements: The tip of the snout has very sensitive touch sensors. If a bug moves, the snout can feel tiny vibrations or small touches from the bug crawling around.
- Detecting tiny electrical signals: Some of the sensors in an echidna’s snout can even notice tiny electrical signals made by a bug’s muscles. This is like sensing the bug’s heartbeat or muscle twitches — it tells the echidna where something alive is moving.
- Probing and digging: The echidna pokes its snout into holes or soft wood and uses strong claws to dig a little. While probing, the snout keeps feeling and listening for moving bugs.
- Sticky tongue to catch bugs: When the echidna finds a bug, it shoots out a long, sticky tongue to grab the insect and pull it back into its mouth.
So, the echidna finds moving bugs by smelling, feeling small touches and vibrations, and even sensing tiny electrical signals — then it digs and uses its sticky tongue to eat the bugs.
Fun tiny experiment: Close your eyes and let a friend gently move a small toy on the table under your fingertips. Can you tell where it is by feeling the tiny movement? Echidnas do something similar with their noses.
