List of pilosans

List of pilosans 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 pilosans rather than just read about it. In short: Pilosa is an order of placental mammals. Members of this order are called pilosans, and include anteaters and sloths.

Key takeaways

List of pilosans 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 pilosans to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of List of pilosans from memory before moving on to harder problems.

Reference excerpt

Pilosa is an order of placental mammals. Members of this order are called pilosans, and include anteaters and sloths. They are found in South and Central America, generally in forests, though some species are found in shrublands, grasslands, and savannas. Pilosans primarily eat insects and leaves. They range in size from the silky anteater, at 36 cm (14 in) plus a 18 cm (7 in) tail, to the giant anteater, at 120 cm (47 in) plus a 90 cm (35 in) tail. No pilosans have population estimates, but the maned sloth is categorized as endangered and the pygmy three-toed sloth is categorized as critically endangered. The ten extant species of Pilosa are divided into two suborders: Folivora, the sloths, and Vermilingua, the anteaters. Folivora contains two families: Bradypodidae, containing four species in one genus; and Choloepodidae, containing two species in one genus. Vermilingua also contains two families: Cyclopedidae, containing a single species, and Myrmecophagidae, containing three species in two genera. Dozens of extinct prehistoric pilosan 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 pilosan's range is provided. Ranges are based on the IUCN Red List for that species unless otherwise noted. All extinct species or subspecies listed alongside extant species went extinct after 1500 CE, and are indicated by a dagger symbol "†".

Classification The order Pilosa consists of ten extant species in two suborders: Folivora, the sloths, and Vermilingua, the anteaters. Folivora contains two families: Bradypodidae, containing four species in one genus; and Choloepodidae, containing two species in one genus. Vermilingua also contains two families: Cyclopedidae, containing a single species, and Myrmecophagidae, containing three species in two genera. Many of these species are further subdivided into subspecies. This does not include hybrid species or extinct prehistoric species.

Pilosans 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.

Suborder Folivora

Bradypodidae

Choloepodidae

Suborder Vermilingua

Cyclopedidae

Myrmecophagidae

Worked examples

Example 1 — a first encounter with List of pilosans

Start with the simplest possible case. Write down what List of pilosans 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 pilosans 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 pilosans 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 pilosans

In research: List of pilosans 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 pilosans 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 pilosans is common in secondary-school and first-year university syllabi. It links to neighbouring topics Lists of animal species, Lists of placental mammals, Pilosa, so understanding it makes those chapters shorter.
In everyday life: Look for List of pilosans 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.
