    What strange adaptations would you like to share?

    This fellow looks very pleased with himself, and why wouldn't he be with his splendid four-headed penis?

    The Tasmanian echidna is thought to have developed this extraordinary love appendage so that the male can come in both ovaries at once. link

    For me it's behavioural stuff - like the caterpillar that is taken into ants nests and is tended through the pupal stage because it smells like them..

    Then the double whammy where a wasp lays its egg in the caterpillar first so it's actually a wasp that hatches out.

    Yeah, good shout for parasitoid wasps. This is what Darwin had to say about them:

    Wasps are bastards :D

    Although fig wasps are amazing. A fig is an inverted flower. The reproductive parts are inside and never see the sun. A wasp enters the fig through a small hole and lays its eggs. The hole closes up. The eggs hatch and the grubs feed on the nectar inside. The grubs turn into wasps. The males mate with the females and then die. Pollen is made in the flowers at last, the wasps chew a new hole and the new females leave the fig, covered in pollen. A female finds another fig to lay its eggs in. It enters the fig through the small hole and fertilises it before dying 48hrs into its life as an adult. The figs and wasps cannot survive without each other.

    It's ok, the cultivated varieties don't need pollenation to produce the fruit.
    Wild figs are a little crunchy, however.

    My QI book of Facts says that 60% of all wildlife in the jungle relies on figs for its survival.

    There are parasites that infect the brains of insects and effectively take over them, making them act in the best interests of the fungus. Funky shit.

    This got me thinking about whether the human brain still has those primitive bits that could potentially be hijacked by a parasite...

    The book does not go into details. In that respect, it is a poor relation of the show.

    Giraffe how the fuck did that work?
    Seriously millions of years of stretching or what?

    Yep.
    The Walker's Gazelle is a good example of where such a trait might have started.

    It's more neck and ears than animal now -- twisted and evil.

    That's the fungus Cordyceps - It makes ants wander away from their nest to a high spot (which helps spread the fungus around, and helps the spores cover a larger area) then bursts out of the ant's brain.



    As for humans - what about things like sneezing, coughing and scratching. I know they're all reactions of the human body to types of infection, but some they're all beneficial to diseases too. Might a flu virus aggravate your lungs specifically to have you coughing viruses all over the place?

    Here they are feeding on tippy toes.

    They have special adaptations in their hips to allow that :)

    I'm enjoying this thread because we've nearly finished watching all of Attenborough's Life of... series at home and they're full of great examples.

    I've posted this before, but the thread really needs a tongue-eating louse, cymothoa exigua. It eats away at a fish's tongue then attaches itself to the stump to nab food on the way down. The fish lives on with a louse for a tongue.
