Questions and answers

  1. Easy Why must a resting crocodile open its mouth instead of sweating?

    Crocodiles do not have sweat glands in their scaly skin, so they release excess heat through their moist mouths.

  2. Easy Where do wild poison dart frogs get the dangerous toxins on their bodies?

    Wild poison dart frogs accumulate their defensive toxins by eating poisonous insects like ants and beetles.

  3. Easy Why does an older veiled chameleon's crest help scare away rival lizards?

    The towering crest makes the chameleon look significantly larger and more threatening during territorial disputes.

  4. Medium Roughly how long can the fangs of a mature Gaboon viper grow in centimeters?

    The fangs of a Gaboon viper can grow up to around five centimeters long, the longest of any snake.

  5. Medium Why did giant tortoises on Aldabra Atoll thrive while Galapagos populations were nearly wiped out by sailors?

    Aldabra was far more isolated, lacked fresh water, and was surrounded by treacherous reefs that deterred visiting ships.

  6. Medium Why do pit vipers have sensory pits on both sides of their face instead of just one?

    Having dual pits lets them triangulate distance and direction to strike their prey accurately in the dark.

  7. Hard How did the Cretaceous giant Deinosuchus achieve its enormous body length compared to modern crocodilians?

    It achieved giant body dimensions by maintaining a standard juvenile growth rate over a vastly longer lifespan.

  8. Hard Which anatomical adaptation allows male natterjack toads to generate enough acoustic power for their trill to rival deep-croaking, much larger species?

    An unusually large single vocal sac beneath the chin acts as an efficient resonator that amplifies sound pressure enormously.
