Elapidae (cobras, kraits, taipans, mambas, coral snakes; order Squamata, suborder Serpentes) A family of venomous snakes which have short, firm, grooved fangs at the front of the mouth. The venom is mainly neurotoxic (i.e. a nerve poison). Generally these are elongate, agile snakes, active at dusk or dark. Their prey consists mainly of small vertebrates. Bungarus (kraits) of south-east Asia grow up to 2 m long; they are nocturnal and feed almost exclusively on other snakes. The genus Dendroaspis (mambas) of Africa includes the black mamba which grows up to 4.25 m long and has been recorded moving at 11 km/h across country and the smaller (up to 2.7 m), arboreal green mamba. Ophirphaguse hannah (King Cobra) of southern Asia, the longest of all venomous snakes, sometimes exceeds 5m; its neck ribs can be spread to form a small hood. There are about 200 species, found on every continent except Europe.

Citation styles 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, cannot guarantee each citation it generates. Therefore, it’s best to use 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:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most 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.
