Hedgehogs are easily recognized by their spines, which are hollow hairs made stiff with keratin. [6] Their spines are not poisonous or barbed and, unlike the quills of a porcupine, do not easily detach from their bodies. However, the immature animal's spines normally fall out as they are replaced with adult spines.
Czech hedgehogs were especially effective in urban combat, where a single hedgehog could block an entire street. Czech hedgehogs thus became a symbol of "defense at all costs" in the Soviet Union; hence, the memorial to Moscow defenders, built alongside the M-10 highway in 1966, is composed of three giant Czech hedgehogs.

She said: "We are not getting the cold winters we used to get, so there is no need for the hedgehogs to hibernate as their food is still available to them while the ground is not frozen.
Desert Hedgehogs are the most closely related to Drosophila Hh. Additional gene duplications occurred within some species [15] such as the zebrafish Danio rerio, which has an additional tiggywinkle hedgehog gene in the sonic group. Various vertebrate lineages have adapted hedgehogs to unique developmental processes.
Furry hedgehogs are teardrop-shaped, with faces ending in a long, narrow snout, not unlike a mini armadillo without a shell, or something halfway between a mouse and a shrew.
Female four-toed hedgehogs do not go into estrus during any particular season, and are fertile throughout the year, although mating is most common during the rainy season, when food is most abundant. The female typically gives birth to a single litter each year, which may contain from two to ten hoglets, with four or five being most typical.
