Torpedinidae (electric ray, numbfish; superorder Batoidimorpha, order Rajiformes) A family of marine rays that have a rounded outline, a stout trunk with a short tail fin, and a soft skin. The eyes are small or rudimentary. The spineless two dorsal fins are well developed. All members of the family possess a pair of powerful electric organs derived from the branchial musculature and capable of delivering very unpleasant electric shocks to anyone treading on them. Torpedo nobiliana (Atlantic torpedo), 1.8 m, is one of the larger species of electric rays. There are about 35 species, distributed world-wide in coastal regions.

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.
