Question 1

Which bird is famous for laying its eggs in the nests of other birds?

Correct answer: Cuckoo

Many cuckoo species practise brood parasitism: females lay eggs in other birds' nests, leaving the host birds to incubate the eggs and raise the chicks. This behaviour varies among cuckoo species.

Question 2

Which of these characteristics is generally associated with carnivorous animals, particularly predators?

Correct answer: All of these

Carnivorous predators commonly use sharp teeth and claws to catch and consume prey, and they may display aggressive behavior while hunting or defending resources.

Question 3

What is the normal body temperature of a healthy platypus?

Correct answer: About 32°C

The platypus has a lower body temperature than most other mammals, around 32°C. It is a monotreme, one of the few mammal groups that lay eggs rather than giving birth to live young.

Question 4

Which mammal is known for rectangular pupils?

Correct answer: Goat

Goats have horizontal, elongated pupils that can look rectangular. This eye shape gives grazing prey animals a wide view of their surroundings, helping them detect potential threats.

Question 5

What is the world's largest living species of lizard?

Correct answer: Komodo dragon

The Komodo dragon is the world's largest living lizard. It is native to a small group of Indonesian islands, where it hunts and scavenges a range of animals.

Question 6

Which big cat is native to the Americas and has the strongest bite relative to body size among big cats?

Correct answer: Jaguar

The jaguar is the largest cat native to the Americas. It has a powerful bite and often kills prey by biting through the skull, rather than relying only on a throat bite.

Question 7

Which marine mammal has prominent tusks in both sexes?

Correct answer: Walrus

Both male and female walruses grow tusks, which are elongated canine teeth. Walruses use them in social displays and to help haul themselves onto sea ice or shore.

Question 8

Which animal is known for the longest lifespan among vertebrates, with some individuals living for centuries?

Correct answer: Greenland shark

Greenland sharks are exceptionally long-lived vertebrates; scientific estimates suggest some may live for several centuries. The estimates are based on radiocarbon dating of proteins in their eye lenses, so individual ages are uncertain.

Question 9

Which of these amphibians is part of a Chinese species complex that includes the world's largest living amphibians?

Correct answer: Chinese giant salamander

Chinese giant salamanders include multiple distinct species, rather than one species spread across China. ZSL's research identifies this hidden diversity among the world's largest amphibians.

Question 10

Which animals are the closest living relatives of koalas among these choices?

Correct answer: Wombats

Koalas and wombats are both marsupials and belong to the order Diprotodontia. Koalas are specialised tree-dwelling leaf eaters, while wombats are burrowing herbivores.
