Hedgehogs include desert hedgehogs, "Atelerix" and others. Mammals include foxes, wild cats, hares, hedgehogs, weasels, martens and wild boar. Mammals that eat slugs include foxes, badgers and hedgehogs. These species infect bats, rodents, hedgehogs, and shrews. Today, mammals include shrews, voles, badgers, otters, stoats, weasels, hedgehogs and fifteen species of bat. Porcupines are rodents and hedgehogs belong to a separate order. Denmark is also home to smaller mammals, such as polecats, hares and hedgehogs. There are hedgehogs, martens, and snakes such as vipers and grass snakes. Insectivores are taken in low numbers including moles, shrews and hedgehogs. Badgers also compete with hedgehogs for food. Similar adaptations are seen in other small predatory mammals such as mongooses and hedgehogs. The largest orders are the rodents, bats and Eulipotyphla (hedgehogs, moles, shrews, and others). The desert hedgehog is one of the smallest of hedgehogs. Tetlock divided experts into "foxes" who maintained multiple hypotheses, and "hedgehogs" who were more dogmatic. The quills tend to be longer than other hedgehogs for better protection against predation.
