Hedgehog spines, SEM
Hedgehog spines. Coloured scanning electron micrograph (SEM) of spines on a European hedgehog (Erinaceus europaeus). A spine is a modified hair made from the protein keratin. The interior (not seen) is hollow and crossed with transverse septa, making the spine strong but light. Adult hedgehogs have about 8000 spines, which are used to protect against predators.
