Soricomorpha is an order of placental mammals that includes the true shrews (family Soricidae); moles, shrew-moles, anddesmans (family Talpidae); solenodons (family Solenodontidae), and members of the extinct family Nesophontidae. These families were originally placed in the now extinct order Insectivora. However, Soricomorpha is itself considered to be paraphyletic and often is replaced with the order Eulipotyphla, with includes members of Soriciomorpha and the family Erinaceidae (hedgehogs and gymnures or moonrats).
Members of this order (as well as the order Eulipotyphla) are small mammals with long, narrow, and pointed snouts. The smallest member of this order, the pygmy white-toothed shrew or Etruscan shrew (Suncus etruscus), is but 3 grams in weight and about 3.5 centimeters in body size. On the other hand, solenodons can reach 60 centimeters in size. Soricomorphs are found in all continents except Australia and Antarctica.
The small size of soricomorphs has resulted in their need to consume considerable amounts of food and the Eurasian pigmy shrew (Sorex minutus) must eat virtually all the time.
Classification
Soricomorpha, which means "shrew-form," includes the three extant families of Soricidae, Talpidae, and Solenodontidae, and the extinct family Nesophontidae. Soricidae (true shrews) is the family with the most species, with about 300 species. Talpidae (moles, shrew-moles,and desmans) has about 42 known species, and Solenodontidae (solenodons) has two known extant species and two known extinct specis. The final family Nesophontidae (West Indies shrews) placed in this order is only known in the fossil record.
In previous years, the soricomorphs formed a significant group within the former order Insectivora. However, that order was shown to be polyphyletic and various new orders were split off from it, including Afrosoricida (tenrecs and golden moles), Macroscelidea (elephant shrews), and Erinaceomorpha (hedgehogs and gymnures), leaving just the four families, leaving Insectivora empty and disbanded.
Subsequently, Soricomorpha itself was shown to be paraphyletic, because Soricidae shared a more recent common ancestor with Erinaceidae than with other soricomorphs (Roca et al. 2004). The combination of Soricomorpha and Erinaceidae, referred to as order Eulipotyphla, has been shown to be monophyletic (Beck et al. 2006).
