STRANGER THINGS

Nature is truly unbelievable. Ben Hoare, the author of Weird and Wonderful Nature, goes in search of evolution's craziest creatures

AIthough Earth is our familiar home, it is also a weird and wonderful place. And the more we learn about the bizarre creatures we share it with, the weirder and more wondrous it becomes.

Are there really spiders who cook their own supper? Marine animals with exploding backsides? Caterpillars disguised as poo, or beetles that look like mini JCBS? Amazingly, the answer is yes.

Long and short of it

Let's start with those beetles. They are called giraffe weevils and live only in Madagascar (where, by the way, many of the local animals, including lemurs, have evolved to look unlike anything else on the planet). Scientists know of more than 400,000 species of beetle so far a staggering number, yet none of the others have necks quite like these red and black beauties. In male giraffe weevils, their jointed necks stretch so far that their tiny heads are four times taller than the rest of their bodies. You can see how they got their name, but what are those magnificent necks for? The answer is fighting. Rival male weevils neck-wrestle to impress females and win the chance to mate. By a curious coincidence, actual giraffes do the same thing! What about female weevils? Their necks are far shorter and they use them for rolling leaves to make their nests.

Other animals use their body parts to help them adapt to their environment. Russia's saiga antelope has a nose so huge and droopy, it is almost a trunk. It looks a bit odd, but is ideal for life in dusty plains, since it filters dirt from the air. The antelope's massive hooter also heats up incoming air when it is cold, and helps cool air when it is hot, ensuring that the animal is always comfortable.
