Echidna Behavior and Adaptations

The spiny anteater, or echidna, is equipped with unique features for survival. It uses its electro-detecting nose and long tongue to hunt insects. Its spikes serve as a defense against predators like dingoes. In bushfires, it digs underground and enters a state of mini-hibernation to survive low oxygen levels.

What unique feature does the echidna's nose have?

• It can detect electric signals.

• It can change color.

• It can grow longer.

• It can emit a loud noise.

How does the echidna use its tongue?

• To catch fish.

• To navigate ant tunnels.

• To climb trees.

• To dig holes.

What is the primary prey of the echidna?

• Fish

• Insects

• Small mammals

• Birds

What role do the echidna's mucus glands play?

• They help in digestion.

• They help in swimming.

• They sense electric signals from prey.

• They produce a sweet scent.

What is the primary function of the echidna's spikes?

• To serve as a defense mechanism.

• To attract mates.

What happens to the echidna's metabolism during a bushfire?

• It increases significantly.

• It remains the same.

• It decreases as the echidna enters a mini-hibernation.

• It fluctuates randomly.

What is the echidna's response to low oxygen levels during a fire?
