Hi there! Do you know what an echidna is? It's a small animal that looks a bit like a porcupine because it has lots of little spikes on its back. These spikes help keep the echidna safe.
When an echidna feels scared, like if there is a fire or a hungry animal nearby, it digs into the dirt with its strong claws. It hides so that most of its body is underground, and only its spiky back is sticking out.
Why do you think it shows only its spiky back? That's right! Because the spikes are sharp and can protect the echidna from getting hurt. So, the echidna stays safe by hiding in the dirt and using its spikes like a shield.
Isn't that a smart way to stay safe?
