The European Hedgehog (Erinaceus europaeus) is a hedgehog species native to western and northern Europe. Adults are 20–30 cm (7.9–11.8 in) in length, weighing from 600 to 1,200 g (21 to 42 oz), depending on the season, with males slightly larger than females.
The male echidna's penis is 7 centimetres (2.8 in) long when erect, and its shaft is covered with penile spines. [29] These may be used to induce ovulation in the female.
