Crocidura sapaensis is a species of white-toothed shrew native to northern Vietnam. It was first described in 2013 and its specific name derives from the Sa Pa where it was discovered. [2]
Crocidura sapaensis is very similar in appearance to the Hainan Island shrew (Crocidura wuchihensis) and it was only recognised as a separate species in 2013 after molecular analysis. This shows that C. sapaensis is more closely related to the Indochinese shrew (Crocidura indochinensis), however these two species are more morphologically distinct. There may have been convergence between C. wuchihensis and C. sapaensis due to them occupying similar ecological niches. [3]
Crocidura sapaensis is a small shrew with a relatively long tail. Its head and body length ranges from 50 to 65 mm (1.97 to 2.56 in) and its tail length from 37 to 47 mm (1.46 to 1.85 in). Its short fur is a dark greyish-brown colour. The tail is a similar colour but slightly paler underneath. The most significant morphological difference between this species and C. wuchihensis is the structure of the third molar in the lower jaw. [3]
Crocidura sapaensis is found in several different types of habitat in the vicinity of Tram Ton Station of Hoang Lien National Park. These include primary forest with large trees, mixed evergreen forests, clearings, grassy glades and the wooded banks of streams. It was most common in slightly disturbed, mixed forests and was found at altitudes of between 1,930 and 2,200 m (6,330 and 7,220 ft) above sea level. [3]
At all times of year, there seem to be more males than females of this species. Pregnant females were found between May and July and the average size of litter was three. [3]
The white-toothed shrews or Crocidurinae are one of three subfamilies of the shrew family Soricidae.
The northern short-tailed shrew is the largest shrew in the genus Blarina, and occurs in the northeastern region of North America. It is a semifossorial, highly active, and voracious insectivore and is present in a variety of habitats like broadleaved and pine forests among shrubs and hedges as well as grassy river banks. It is notable in that it is one of the few venomous mammals. The specific epithet, brevicauda, is a combination of the Latin brevis and cauda, meaning "short tail".
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 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.
Jenkins's shrew tenrec is a species of mammal in the family Tenrecidae. It is endemic to Madagascar. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical dry shrubland. It is threatened by habitat loss.
The Cyrenaica shrew or Alexander's shrew is a species of white-toothed shrew in the family Soricidae which is endemic to Libya.
The Asian gray shrew is a species of mammal in the family Soricidae. It is found in Bhutan, Cambodia, China, India, Laos, Malaysia, Myanmar, Nepal, Pakistan, the Philippines, Thailand, and Vietnam. It is one of the commonest species within its range and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
Hildegarde's shrew is a species of mammal in the family Soricidae. It is found in Burundi, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Ethiopia, Kenya, Rwanda, and Tanzania. Considered by some authorities to be a subspecies of Crocidura gracilipes, it is now recognised as a separate species, with a chromosome number of 2n = 52. This is one of three species of small mammal named by the British zoologist Oldfield Thomas in honour of anthropologist Hildegarde Beatrice Hinde.
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 swamp musk shrew, or musk shrew, is a species of mammal in the family Soricidae. It occurs in Angola, Botswana, Democratic Republic of the Congo, Mozambique, Namibia, South Africa, Eswatini, Zambia and Zimbabwe. Its natural habitat is swamps, and it is a common species in suitable habitats, with the International Union for Conservation of Nature listing it as being of "least concern".
The Ugandan musk shrew is a species of mammal in the family Soricidae. It is found in Uganda, the Democratic Republic of Congo and the Central African Republic. Its range, population size and habits are poorly known.
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 in length, making them one of the smallest shrews in Egypt. They weigh 7 grams.
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".
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".
Crocidura hikmiya is a species of shrew described from the rainforests of Sri Lanka, based on both morphological and molecular data. Its closest sister species is the Sri Lankan long-tailed shrew, another Sri Lankan crocidurine shrew restricted to the high-elevation habitats of the Central Highlands. C. hikmiya has a shorter tail than the Sri Lankan long-tailed shrew. Most of the other characteristics that distinguish the two species are osteological natured .
Crocidura phanluongi is a species of shrew in the genus Crocidura from southern Vietnam and nearby Cambodia. It is a somewhat small, gray shrew with an ecologically diverse distribution.
The Chinese white-toothed shrew is a species of mammal in the family Soricidae.
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.
