Answers

Natural history

1. True. Many whales have 'baleen' teeth which they use to sieve food. These plates strain the water out but prevent the krill, a small fish, it gulps with the water from getting out. The whale then swallows the krill.

2. The giraffe's long neck (which is the longest in the animal kingdom) comprises just seven bones - the same number of bones humans have on their short neck.

3. Yes. These bats which are found in Mexico and South America drink the blood of animals by first puncturing the skin and then lapping up the blood which flows from the wound.

4. Bats which fly by echolocation literally 'shout' as they fly. If they receive an echo, they know something is in their path.

5. True.

6. A squid has 10 arms.

7. They are all butterflies.

8. The heaviest flying bird is the mute swan. An adult bird may weigh as much as 18 kg (40 lbs)!

9. No. The various species of zebra - the Burchell's, mountain and Grevy's all have different coat patterns. Even the various subspecies have different coats. Though the coats all look alike superficially, scientists can tell them apart by comparing the width of the stripes and overall patterning.

10. A goose barnacle is a tiny marine animal related to shrimps and crabs. It was believed long ago that the barnacle grew into gees because they had heads resembling gees. The name originated from this belief.

11. A pearl is formed when a tiny piece of grit or sand gets trapped inside the shell of an oyster. As this irritates the oyster it produces a layer of mother of peal around it to prevent the particle from harming its inner organs.A layer after layer of mother of pearl is produced to form the pearl.

12. Mother of pearl is a substance produced by the oyster to normally coat the inside of its shell.

13. Mammals usually give birth to live young. However, there are mammals such as the platypus and the echidna also known as the spiny ant eater, which lay eggs.

14. Yes. Some brilliantly coloured frogs of Central and South America produce a venom which can kill humans. In fact some natives living in the forests in these areas use the poison from these frogs to coat their arrows. The frogs are known as poison arrow frogs.

15. The most poisonous frog in Columbia is the Kokoi. It is a 2.5 cm (1 in) long frog but its skin provides poison sufficient to kill 50 men!
