Indridae

Indridae (formerly Indriidae; indri, sifaka; order Primates, suborder Strepsirrhini) A family of primitive primates that includes the largest of the living lemurs (up to 1 m long). Its members are distinguished from other lemurs by the absence of the lower canine and by having one upper and one lower premolar tooth. The tail is short in some species, and the ears may be concealed beneath long hair on the sides of the head. They are fully arboreal, although they visit the ground, and are exclusively vegetarian. There are six species (one discovered in 1988) in three genera: Indri (indri), Propithecus (sifaka), and Avahi (woolly indri). They are all confined to Madagascar.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
