A bibliography is a listing of citations -- usually including the author, title, publication information, etc -- of the sources that you have used or plan to use for your research topic. (Ellison, 2010, p. 55)
Gelatinous zooplankton are fragile animals that live in the water column in the ocean. The most commonly encountered organisms include ctenophores, medusae, salps, and Chaetognatha in coastal waters. (https://en.wikipedia.org/wiki/Gelatinous_zooplankton)
Note
All jellyfish are gelatinous zooplankton, but not all gelatinous zooplankton are jellyfish.
