The long-eared hedgehog only breeds once a year in the summer months of July through September. The presence of spines does not inhibit this species ability to reproduce. [7] Long-eared hedgehogs gestation period is 35–42 days. The female has 8–10 nipples and often has 2–3 babies. [3] After just one week the babies start eating solid food.
A Southern African hedgehog is covered with spines all over its body except for its face, belly and ears, and these spines are made of keratin protein with a hollow shaft and a muscle for each spine. [2] These unprotected body parts are covered with fur. They are dark brown and their spines are typically white at the base and dark brown at the tip.
Hedgehogs all have spines on their backs, while gymnures have fur. No erinaceids have population estimates, but the Hainan gymnure and Dinagat gymnure are categorized as endangered species . The twenty-four extant species of Erinaceidae are divided into two subfamilies: Erinaceinae , containing sixteen hedgehog species in five genera , and ...
