The Cyrenaica shrew or Alexander's shrew (Crocidura aleksandrisi) is a species of white-toothed shrew in the family Soricidae which is endemic to Libya.
The Cyrenaica shrew is a small shrew which is very similar to the widespread lesser white-toothed shrew of Europe and Asia, both species have teeth which lack the red colouration on the crowns of the teeth. They are small mammals with paler fur underneath and a pointed muzzle and a long tail. [3]
The Cyrenaica shrew is endemic to Libya, specifically to the province of Cyrenaica where it is found from sea level up to 200 to 300 m. Specimens were collected from the 1960s through the 1990s, and there were no signs that the population had declined or that there were any major threats to the species in its restricted range and is therefore assessed as Least Concern. [1]
The Cyrenaica shrew is found in Mediterranean vegetation such as scrub and also in littoral and rocky areas. It is thought to occur in degraded habitats, and to be largely terrestrial and nocturnal. [1] It is very closely related to the lesser white-toothed shrew and is likely to share that species rather sociable habits and to "caravan", i.e. the young follow their mother in a line holding their predecessor's tail in their mouth so that the family stays together while foraging or seeking shelter. [4] It seems to be relatively common and its skulls are frequently found in the pellets of owls collected from within their range. [1] The group of shrews this species belongs to are also known as "musk shrews" because of the musky scented secretions they produce and use to scent mark their territories by dragging their bellies along the ground. [4]
The white-toothed shrews or Crocidurinae are one of three subfamilies of the shrew family Soricidae.
The lesser white-toothed shrew is a tiny shrew with a widespread distribution in Africa, Asia and Europe. Its preferred habitat is scrub and gardens and it feeds on insects, arachnids, worms, gastropods, newts and small rodents, though its diet usually varies according to the biotope where it lives. The closely related Asian lesser white-toothed shrew was once included in this species, but is now considered to be a separate species.
The greater white-toothed shrew is a small insectivorous mammal found in Europe and North Africa. It is the most common of the white-toothed shrews. This species is found along the Mediterranean, Netherlands, Belgium, Ireland, Germany and Portugal; in addition, the Osorio shrew of the Canary island of Gran Canaria, originally described as a separate species, was later discovered to be a population of introduced greater white-toothed shrew. Furthermore, a subspecies of the greater white-toothed shrew, Crocidura russula ibicensis, is found on the Mediterranean island of Ibiza. In April 2008, the greater white-toothed shrew was discovered in Ireland as well. Its preferred habitats are grassland and woodland. It is slightly larger than the lesser white-toothed shrew but otherwise very similar and can often be distinguished only by close inspection of its teeth which are unpigmented.
The São Tomé shrew is a white-toothed shrew about 3.0 in (7.6 cm) long found only on São Tomé Island, São Tomé and Príncipe. It is listed as a critically endangered species due to habitat loss and a restricted range. It was discovered in 1886. The population continues to decrease, making these animals rare. It is found only on São Tomé Island, a small island that is actually a shield volcano that rises out of the Atlantic Ocean.
The genus Crocidura is one of nine genera of the shrew subfamily Crocidurinae. Members of the genus are commonly called white-toothed shrews or musk shrews, although both also apply to all of the species in the subfamily. With over 180 species, Crocidura contains the most species of any mammal genus. The name Crocidura means "woolly tail", because the tail of Crocidura species are covered in short hairs interspersed with longer ones.
The Sulawesi shrew is a species of mammal in the family Soricidae. It is endemic to the central and northern provinces of Sulawesi in Indonesia. It is a fairly common species and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
The bicolored shrew or bicoloured white-toothed shrew is a species of mammal in the family Soricidae. It is found in eastern, central and southern Europe and in western Asia. It is a nocturnal species and feeds on insects and other small creatures. Several litters of young are born during the warmer months of the year in a nest of dry grasses in a concealed location.
The black-footed shrew is a species of mammal in the family Soricidae. It is endemic to northern and central Sulawesi, Indonesia where it lives on the floor of the tropical forests. The International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
The African giant shrew is a species of white-toothed shrew. It also is known as, Mann's musk shrew, Euchareena's musk shrew, or Olivier's shrew. It is native to Africa, where it has a widespread distribution and occurs in many types of habitat. Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, dry savanna, moist savanna, arable land, rural gardens, urban areas, and heavily degraded former forest. In the Nile Valley it is found near human habitation, where it is considered to be a pest. It is a common species and is listed by the International Union for Conservation of Nature as being of "least concern".
The Egyptian pygmy shrew or sacred shrew is a species of mammal in the family Soricidae. It is endemic to Egypt. Its natural habitat is arable land. It is threatened by habitat loss, partially caused by the construction of the Aswan Dam. They are 48–62 mm (1.9–2.4 in) in length and weigh 7 g (0.25 oz), making them one of the smallest shrews in Egypt.
The Sulawesi white-handed shrew or Temboan shrew is a species of mammal in the family Soricidae. It is endemic to the island of Sulawesi in Indonesia. It is a fairly common species and the population seems stable so the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
The Asian lesser white-toothed shrew is a species of mammal in the family Soricidae. It is found in Siberia, China, Korea, and Japan.
Whitaker's shrew is a species of mammal in the family Soricidae. It is found in Western Sahara, Algeria, Morocco, Tunisia. Its natural habitats are subtropical or tropical dry shrubland, rocky and sandy coasts. It is a fairly common species and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
The Cretan shrew is a species of mammal in the family Soricidae. It is endemic and exclusive to the island of Crete, Greece. Its natural habitat is temperate shrubland, and the animal is threatened by habitat loss. It is found in the mountainous highlands of Crete, having been displaced from lower altitudes by the lesser white-toothed shrew.
The Indochinese shrew is a species of white-toothed shrew native to Southeast Asia. It was first identified in 1922 by Herbert C. Robinson and C. Boden Kloss. The species is often taxonomized as a subspecies Horsfield's shrew, but bears a different range, occurring in Myanmar, Vietnam, and the Yunnan province of China. C. indochinensis is on the smaller end of shrews, with dark brownish gray fur and a long, slender tail.
Sokolov's shrew is a species of mammal in the family Soricidae. It is endemic to Vietnam.
