Descrição: A tick uses a foldable pad between its claws that can spread out like a fan and adhere to the smoothest of surfaces. Ticks lie in wait on plants and leaf litter until they can latch on to a passing bird or animal. They then search their host for a suitable place to clamp down and sup blood. To do all this, a tick needs legs that can grip a variety at surfaces and support the increase in body weight as it feeds--a female tick can swell to 135 times her initial size after a meal. To work out how it's done, Dagmar Voigt and Stanislav Gorb at the University of Kiel, Germany, looked at the legs of the castor bean tick (Ixodes ricinus) using a microscope.
