9. What type of creature is the lightest mammal (as an adult)?
(a) A bat, (b) a dog, (c) a lemur, (d) a shrew
10. The African elephant holds all kinds of records for size, but it also has the longest pregnancy of any mammal. How long?
(a) 14 months, (b) 17 months, (c) 22 months, (d) 40 months
1(a). The baboons can often be found at rock pools where they harvest 'mermaid's purses', the eggs of sharks. These contain well-developed shark embryos.
2(b). The notion that a camel's humps are full of water is a myth. They instead serve as a storage for fat, which is broken down to provide energy and hydration to the animal.
3(d). Most animals make the same noise the world over, but different cultures interpret that noise differently. While English-speaking countries attribute a 'woof' to a dog, the noise is perceived differently elsewhere.
4(d). And other countries along the Andes mountains. The name is doubly misleading. The animals are not found in any place called Guinea, and are not a type of pig.
5(c) Koalas are, of course, marsupials and not related to the bear family.
6(a) Despite their fearsome reputation, male lions are largely docile animals. Females do much of the hunting.
7(b) Hamsters are known collectively as 'a horde'. Fact.
8(c) Another name for the orca is the killer whale. However, it is not a species of whale but the largest of the dolphin family. (Note for pedants: dolphins, porpoises and whales with teeth do belong to a larger grouping called 'toothed whales', so you could argue that an orca is also a form of whale, although you'd have to concede that dolphins are, too.)
9(d) The Etruscan shrew has an average weight of 1.8g. If you said 'bat', then take a half-point. The bumblebee bat lives up to its name. At 3cm long, it is the smallest mammal by length, but it tends to weigh a little more than the Etruscan shrew.
10(c) Almost two-and-a-half times the length of a human pregnancy. The African elephant also has the biggest ears of any animal. The size is more to do with keeping the animal cool than improving its hearing.
