How an echidna's nose finds moving bugs

Echidnas are funny, spiky animals that eat insects. Their long snout (nose) is super sensitive and helps them find moving bugs. Here is how it works, step by step:

1. Sniff and poke: The echidna pokes its nose into dirt, under logs, or into ant and termite nests to look for food.
2. Sensing tiny movements: Inside the snout there are special sensors. These sensors can feel tiny movements and even tiny electrical signals that bugs make when they wiggle. It is a bit like having tiny antennas that can tell when something is alive and moving.
3. Listen with the nose: The echidna's nose also feels vibrations — little shakes in the ground — when bugs move. So it uses touch and those special sensors together.
4. Grab the bug: When it finds a bug, the echidna quickly flicks out its long, sticky tongue and catches the insect.
5. Eat and repeat: It keeps searching and snapping up bugs until it is full.

Fun fact: Echidnas are special mammals that lay eggs! They use their amazing snout instead of sharp teeth to find and eat lots of tiny insects.

Quick recap: The echidna pokes its snout into the ground, its special sensors feel movement and tiny electric signals, and its sticky tongue catches the bugs.
