The hedgehog's back contains two large muscles that direct the quills. Some light-weight desert hedgehog species with fewer spines are more likely to flee or attack, ramming an intruder with the spines, rolling up only as a last resort. Hedgehogs are primarily nocturnal, with some species also active during the day. Hedgehogs sleep for a large ...
Skull of a four-toed hedgehog. The four-toed hedgehog is an oval bodied animal approximately 210 millimetres (8.3 in) in length and weighing between 250 and 600 grams (8.8 and 21.2 oz). [3] Females are typically larger than males. It has short legs, short tail typically around 2.5 centimetres (0.98 in) in length, a long nose, and small beady eyes.
In biology, taxonomic rank (which some authors prefer to call nomenclatural rank [1] because ranking is part of nomenclature rather than taxonomy proper, according to some definitions of these terms) is the relative or absolute level of a group of organisms (a taxon) in a hierarchy that reflects evolutionary relationships.
Erinaceids are generally shrew-like in form, with long snouts and short tails.They are, however, much larger than shrews, ranging from 10–15 cm (4–6 in) in body length and 40–60 grams (1.4–2.1 oz) in weight, in the case of the short-tailed gymnure, up to 26–45 cm (10–18 in) and 1.0–1.4 kg (2.2–3.1 lb) in the moonrat.
The following classification is based on the taxonomy described by the reference work Mammal Species of the World (2005), with augmentation by generally accepted proposals made since using molecular phylogenetic analysis, as supported by both the IUCN and the American Society of Mammalogists. [1]
The European hedgehog (Erinaceus europaeus), also known as the West European hedgehog or common hedgehog, is a hedgehog species native to Europe from Iberia and Italy northwards into Scandinavia and westwards into the British Isles. [3] It is a generally common and widely distributed species that can survive across a wide range of habitat types ...
Erinaceus is a genus of hedgehog from the family of Erinaceidae. There are four main species of Erinaceus. The range is all across Europe, throughout the Middle East, parts of Russia, and extending to northern China and Korea. The European hedgehog (Erinaceus europaeus) has been introduced to New Zealand.
