The insight that the “jelly web” is far more complex than previously recognized has implications when considering humanity’s far-reaching impacts on the oceans. The second comes from CFOS researchers who have been measuring tiny jellyfish — such as the common pink helmet jellyfish — on the Seward Line, a … Jellyfish are some of the sea’s most extraordinary creatures. Comb jellies are very fragile, up to 96% water, but voracious predators of other jellies. Thus, the principal predators of mixed zooplankton assemblages have been typically identified as myctophid or other micronektonic fishes [29,30,31] and decapod crustaceans [32,33]. Despite their beautiful and enchanting appearance, jellyfish are highly efficient predators. The normal rhythms of daily life continue in the gloom.

Besides, a group of jellyfish is called a bloom, swarm, or smack. Clams open and close cyclically, seabirds hunt in almost total darkness, ghost shrimps and sea snails gather in kelp forests to reproduce, and deep-water species such as the helmet jellyfish surface when it’s dark enough to stay safe from predators. As their name would suggest, jellyfish aren’t exactly ahi tuna. The research greatly enhances scientists’ understanding of deep-sea food webs by documenting the importance of soft-bodied predators like jellyfish. Jellyfish have drifted along on ocean currents for millions of years, even before dinosaurs lived on the Earth. Your aquaria of marine predators can educate your people about life under the sea. The goal of the Polarfuchs team was simple—to figure out what marine predators had to gain from eating their gelatinous neighbors. 8 Helmet Jellyfish.
