Margaret Seagull is a taxidermist and osteologist (a person who studies the structure and function of the skeleton and bony structures), and on her Instagram account you can find a variety of taxidermy/osteology related posts (which may make some squeamish).

A recent series featuring the skeleton of a hedgehog, along with its distinctive spine and hollow ‘hairs’ made stiff with keratin, was recently shared on reddit where I came across the series of images.

According to Wikipedia, their spines are not poisonous or barbed and unlike the quills of a porcupine, do not easily detach from their bodies.
