Question 1

True or false: They are one of only two mammals that lay eggs, the other being the platypus.

Accepted Answer

True. Echidnas and platypuses are monotremes, the sole egg-laying mammals still alive today.

Question 2

True or false: Short-beaked echidnas can shoot their spines like porcupines do.

Accepted Answer

False. Echidnas cannot shoot spines; they rely on digging and curling into a spiky ball for defense, not projectile quills.

Question 3

True or false: They have a prehensile tail used to grip branches while climbing.

Accepted Answer

False. Echidnas have a tiny, stubby tail with no gripping ability; it's mostly used for balance and covering their rear.

Question 4

True or false: Echidnas are completely toothless and use their long sticky tongue to catch prey.

Accepted Answer

False. They lack teeth as adults, but hatchlings have temporary teeth. Their tongue indeed catches ants and termites.

Question 5

True or false: Their spines are actually modified hairs made of keratin, like porcupine quills.

Accepted Answer

True. Echidna spines are indeed hardened hairs, composed of keratin, and can be shed and regrown.

Question 6

True or false: Female echidnas carry their young in a pouch like kangaroos.

Accepted Answer

False. Echidnas develop a temporary pouch during breeding to hold eggs and young, but it's not a permanent feature like marsupials.

Question 7

True or false: Short-beaked echidnas can enter a state of torpor to save energy during cold weather.

Accepted Answer

True. They lower their body temperature and metabolism in torpor, sometimes for weeks, to survive food scarcity or cold.

Question 8

True or false: Short-beaked echidnas have a four-headed penis, but only two heads are functional at a time.

Accepted Answer

True. Male echidnas possess a unique four-headed penis; during mating, two heads swell while the other two retract, alternating use.
