List of crocidurines

List of crocidurines is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand List of crocidurines rather than just read about it. In short: Crocidurinae is a subfamily of small mammals in the shrew family Soricidae, which in turn is part of the order Eulipotyphla. A member of this family is called a crocidurine, or a white-toothed shrew.

Key takeaways

List of crocidurines belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect List of crocidurines to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of List of crocidurines from memory before moving on to harder problems.

Reference excerpt

Crocidurinae is a subfamily of small mammals in the shrew family Soricidae, which in turn is part of the order Eulipotyphla. A member of this family is called a crocidurine, or a white-toothed shrew. Crocidurinae is one of three subfamilies in Soricidae, along with the African shrews of Myosoricinae and the red-toothed shrews of Soricinae. They are found in Africa, Europe, and Asia, primarily in forests, savannas, shrublands, and grasslands, though some species can also be found in wetlands, rocky areas, or coastal areas. They range in size from the Etruscan shrew, one of the smallest mammal species at 3 cm (1 in) plus a 2 cm (1 in) tail, to the goliath shrew, at 18 cm (7 in) plus a 14 cm (6 in) tail. Crocidurines primarily eat invertebrates, small mammals, frogs, toads, and lizards. Almost no crocidurines have population estimates, but 23 species are categorized as endangered species, while the Andaman shrew, Harenna shrew, Jenkins's shrew, and Nicobar shrew are categorized as critically endangered, and the Christmas Island shrew was declared extinct in 2025. The 234 extant species of Crocidurinae are divided into nine genera; 192 of them are in Crocidura, the most species of any mammal genus. A few extinct prehistoric Crocidurinae species have been discovered, though due to ongoing research and discoveries the exact number and categorization is not fixed.

Conventions

The author citation for the species or genus is given after the scientific name; parentheses around the author citation indicate that this was not the original taxonomic placement. Conservation status codes listed follow the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. Range maps are provided wherever possible; if a range map is not available, a description of the crocidurine's range is provided. Ranges are based on the IUCN Red List for that species unless otherwise noted. All extinct genera or species listed alongside extant species went extinct after 1500 CE, and are indicated by a dagger symbol "†".

Classification The subfamily Crocidurinae consists of nine genera: Crocidura, containing 191 extant species; Diplomesodon and Feroculus with a single species each; Paracrocidura, with three species; Ruwenzorisorex, with one species; Scutisorex, containing two species; Solisorex, with one species, Suncus, containing nineteen species; and Sylvisorex, containing fifteen species. Subfamily Crocidurinae

Genus Crocidura (white-toothed shrews): 192 species (1 extinct) Genus Diplomesodon (piebald shrew): one species Genus Feroculus (Kelaart's long-clawed shrew): one species Genus Paracrocidura (large-headed shrews): three species Genus Ruwenzorisorex (Ruwenzori shrew): one species Genus Scutisorex (hero shrews): two species Genus Solisorex (Pearson's long-clawed shrew): one species Genus Suncus (musk shrews and pygmy shrews): nineteen species Genus Sylvisorex (forest shrews): fifteen species

Crocidurines 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.

Worked examples

Example 1 — a first encounter with List of crocidurines

Start with the simplest possible case. Write down what List of crocidurines claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of crocidurines before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of crocidurines ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of List of crocidurines

In research: List of crocidurines appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses List of crocidurines in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: List of crocidurines is common in secondary-school and first-year university syllabi. It links to neighbouring topics Lists of animal species, Lists of eulipotyphlans, White-toothed shrews, so understanding it makes those chapters shorter.
In everyday life: Look for List of crocidurines outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
