A skin-skeletal preparation Close-up of the last 5 millimetres (0.20 in) of a hedgehog spine (SEM microscopy) A hedgehog that feels threatened can roll into a tight ball. Hedgehogs roll into a tight spiny ball when threatened, tucking in the furry face, feet, and belly. [7] The hedgehog's back contains two large muscles that direct the quills.
The average mass of a fully grown male is 350 g (12 oz). The main color is brown but there are other colors too.

Spines are found in the fins of most bony fishes, particularly actinopterygians (ray-finned fishes), who have folding fan-like fin made of spreading bony spines called lepidotrichia or "rays" covered by thin stretches of skin.
Three of the new hedgehog species were upgraded from subspecies of Hylomys suillus and are now named H. dorsalis, H. maxi and H. peguensis. The other two are new, Hylomys vorax and Hylomys ...
Like all other hedgehogs Erinaceus is nocturnal and seeks shelter in shrubs and burrows during the day. [6] The common defense mechanism is to roll into a ball with the spines facing outward.
