The loggerhead, Kemp's ridley, olive ridley, and hawksbill sea turtles are omnivorous their entire life. Omnivorous turtles may eat a wide variety of plant and animal life including [[Decapoda|decapods]], seagrasses, [[seaweed]], [[sponge]]s, [[Mollusca|mollusks]], [[cnidaria]]ns, [[Echinoderm]]s, worms and fish.<ref name="Burbidge">{{cite book |last = Burbidge|first = Andrew A|title = Threatened animals of Western Australia|url={{google books |plainurl=y |id=wuVEAAAAYAAJ|page=110}}|year = 2004|publisher = Department of Conservation and Land Management|isbn = 978-0-7307-5549-4|pages = 110, 114}}</ref><ref name="noaa">{{cite web |url=http://www.nmfs.noaa.gov/pr/species/turtles/loggerhead.htm |title=Loggerhead Turtle (''Caretta caretta'') |last1=Bolten |first1=A.B. |year=2003 |work=NOAA Fisheries |access-date=January 31, 2010 |archive-url=https://web.archive.org/web/20100514085206/http://www.nmfs.noaa.gov/pr/species/turtles/loggerhead.htm |archive-date=May 14, 2010 |url-status=live}}</ref><ref>Barbour, Roger, Ernst, Carl, & Jeffrey Lovich.

Loggerhead turtles are regarded as flexible and predators of slow-moving animals. They eat a broad variety of things, including terrestrial insects like ants, planthoppers, and beetles, as well as sea animals and plants. This species' primary diet consists of gelatinous creatures (medusae and ctenophores) and crustaceans, particularly crabs. Sargassum, barnacles, [[Gastropoda|gastropods]], anemones, salps, and pelagic coelenterates have also been found in numerous studies to be loggerhead turtles' primary food sources.<ref>{{Cite journal |last1=Kim |first1=Jihee |last2=Kim |first2=Il-Hun |last3=Kim |first3=Min-Seop |last4=Lee |first4=Hae Rim |last5=Kim |first5=Young Jun |last6=Park |first6=Sangkyu |last7=Yang |first7=Dongwoo |date=2021-11-21 |title=Occurrence and diet analysis of sea turtles in Korean shore |journal=Journal of Ecology and Environment |volume=45 |issue=1 |pages=23 |doi=10.1186/s41610-021-00206-w |doi-access=free |issn=2288-1220}}</ref>
