Desalted ready-to-use jellyfish are low in calories and contain hardly any fat, about 5% protein and 95% water. [9] They do not have much flavor, and may be used to add additional texture and mouthfeel to various dishes. [10] In some areas of Asia, jellyfish is "associated with easing bone and muscle pain." [10]
The lion's mane jellyfish, Cyanea capillata, was long-cited as the largest jellyfish, and arguably the longest animal in the world, with fine, thread-like tentacles that may extend up to 36.5 m (119 ft 9 in) long (though most are nowhere near that large).
The metabolic cost of transport for jellyfish is high when compared to a fish of equal mass. Other jet-propelled animals have similar problems in efficiency. Scallops , which use a similar design to jellyfish, swim by quickly opening and closing their shells, which draws in water and expels it from all sides.
The box jellyfish actively hunts its prey (small fish), rather than drifting as do true jellyfish. They are strong swimmers, capable of achieving speeds of up to 1.5 to 2 metres per second or about 4 knots (7.4 km/h; 4.6 mph). [19] and rapidly turning up to 180° in a few bell contractions. [4] Some species are capable of avoiding obstacles. [4]
She warned against picking up jellyfish, as stinging species like Portuguese man o’ war and lion’s mane can still hurt humans even when the jellyfish is dead.
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.
With beautiful and majestic animals like California condors, water buffaloes and mountain gorillas facing oblivion, the cost of protecting habitats or cutting down on poaching seems negligible.
Jellyfish are slow swimmers, and most species form part of the plankton. Traditionally jellyfish have been viewed as trophic dead ends, minor players in the marine food web, gelatinous organisms with a body plan largely based on water that offers little nutritional value or interest for other organisms apart from a few specialised predators such as the ocean sunfish and the leatherback sea turtle.
