Weapons
We pride ourselves in thinking that nothing is more human than making and using weapons.
A lot of animals have come up with clever ways to create weapons. You've already seen the orangutan spear. The blanket octopus (above) will take the tendrils from a Portuguese Man O'War and wield them like a poisonous whip. Several birds are know to steal human bread and use bread crumbs as bait for fishing. Elephants will use their trunks to throw rocks at predators or annoying humans. The cleverest weapon user is the dolphin. He will grab a poisonous sea snake by the mid-section and swim through a school of fish swing the snake around. The angry snake bites at the fish. The paralyzed fish make an easy feast for the dolphin.
Tool Boxes
Crows and ravens have long been observed choosing and using twigs as tools to get at nutritious insects. What is less well known is that if they find a particularly useful tool they keep it and use it again and again. Some birds have collected a number of twigs and keep them together in a kind of tool box.
A fascinating blog on the subject is Animals Don't Think, kept by someone who knows animals are, in fact, very good thinkers.
