Ziphiidae (bottle-nosed and beaked whales; order Cetacea, suborder Odontoceti) A family of whales in which the snout is long and narrow, in some species with a high, bulging forehead, the dorsal fin and flippers are small, and the tail is only slightly notched at the mid-line. The first two cervical vertebrae are fused, and in Hyperoodon ampullatus (bottle-nosed whale) all the cervical vertebrae are fused. The number of teeth is variable, from one or two pairs in the lower jaw only, to 38 in the upper and 54 in the lower jaw. Ziphiids attain lengths of 4–12 m and are found in all oceans. They dive to considerable depths and feed mainly on deep-sea fish and squid. There are five genera, with 18 species.

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.
