The diet of the ocean sunfish was formerly thought to consist primarily of various jellyfish. However, genetic analysis reveals that sunfish are actually generalist predators that consume mostly small fish, fish larvae, squid , and crustaceans , with jellyfish and salps making up only around 15% of the diet.

Increased abundance of jellyfish negatively impacts fish populations in the same region because jellyfish feed on fish eggs and larvae. [13] Jellyfish and larval fish can also share common dietary preferences. Competition for food resources can result in depleted fish populations. Overpopulation of jellyfish is a concern to humans for many ...
The giant sunfish or bumphead sunfish (Mola alexandrini), [3] (also known as the Ramsay's sunfish, southern sunfish, southern ocean sunfish, short sunfish or bump-head sunfish in various parts of the world), [4] is a fish belonging to the family Molidae. It is closely related to the more widely known Mola mola, and is found in the Southern ...
Marine larval ecology is the study of the factors influencing dispersing larvae, which many marine invertebrates and fishes have. Marine animals with a larva typically release many larvae into the water column, where the larvae develop before metamorphosing into adults.
Also, the blue sea slug specializes in feeding on the Portuguese man o' war, [41] as does the violet sea snail. [42] The ocean sunfish's diet, once thought to consist mainly of jellyfish, has been found to include many species, including the Portuguese man o' war. [43] [44]
A giant species of fish that was first discovered seven years ago washed ashore in Oregon last week, according to marine biologists who study the animal.
The surrounding egg white floats perfectly around the yolk, membrane intact. One of the divers was even able to make the egg 'dance' around by manipulating the current of the water around it.
Chrysaora fuscescens, the Pacific sea nettle or West Coast sea nettle, is a widespread planktonic scyphozoan cnidarian—or medusa, "jellyfish" or "jelly"—that lives in the northeastern Pacific Ocean, in temperate to cooler waters off of British Columbia and the West Coast of the United States, ranging south to Mexico.
