A male bowerbird’s ‘pride’ in the appearance of his bower is of utmost importance in finding a mate. Different types of bowerbirds use one or more specific colours to decorate their bowers. The female will inspect a number of males’ displays and will choose her mate by the most impressive bower (I.e tidy and with a large number of different objects)

The wolverine represents ‘greed’ – viciously guarding carcasses and even urinating on them to stop other animals stealing a scrap.

The caterpillar (in this case a swallowtail caterpillar) represents gluttony because pretty much its only mission is to eat and eat and eat until it’s ready to form a chrysalis!

The shrew represents ‘wrath’ as their incredibly high metabolism gives them a highly strung and vicious disposition. They will fiercely defend their territories and have be known to attack animals twice their size.

This beetle is the ultimate freeloader. Recently discovered in Cambodia, ‘Eocorythoderus incredibilis’ lives its entire life in a termite mound and has evolved some traits which trick the termites into caring for it. It secretes chemicals which mimic those secreted by termite larvae so that the termites will feed it. It has even evolved a little handle on its back so the termites can pick it up and carry it to its food. Being wingless and almost blind it can now only really survive in the safe, warm confines of the termite nest.

OK it’s not exactly lust per se, but dolphins mate several times a day with different sexes to promote bond among within the pod.

Capuchin monkeys demonstrate ‘envy’ – if they see another capuchin being given tastier food (for example a grape over a piece of cucumber, as shown here) they will reject the cucumber, throwing it on the floor or even at the researcher, and demanding a grape of their own.
