Hedgehogs consume about 1/3 of their body weight at night.
They lick and chew objects with unfamiliar odors or that possess bothersome substances, producing
quantities of foamy saliva that they spread over their spines. This is believed to deter predators and is
known as “self-annointing.”
African pygmy hedgehogs are also known as “4-toed hedgehogs.”
Researchers at 2 universities have discovered that the blood of both the European and African
hedgehogs contains a lipoprotein identical to one of those found in human blood. This lipoprotein
contributes to the formation of clots that cause heart attacks. Hedgehogs may eventually contribute a
solution to a human health problem.
A hedgehog can run over six feet per second.
The collective noun is “an array of hedgehogs.”
The first hedgehog was domesticated in 4 B.C.
Hedgehogs are not affected by adder venom
Each hedgie has around 5,000 spines — each of which lasts about a year.
Hedgehogs got their name through their foraging habits.
Hedgies have poor eyesight, but excellent senses of smell and hearing.
