Description
During a recent trip to the Baltimore National Aquarium in Maryland I had the opportunity to photography one of the boldest colored jellyfish. this is the Pacific Nettle. Although it does have a sting it is actually only bothersome to humans.
Here's some more information on this great species off Wikipedia:
Chrysaora fuscescens (commonly known as the Pacific sea nettle or West Coast sea nettle) is a common free-floating scyphozoa that lives in the East Pacific Ocean from Canada to Mexico.
Sea nettles have a distinctive golden-brown bell with a reddish tint. The bell can grow to be larger than one meter (three feet) in diameter in the wild, though most are less than 50 cm across. The long, spiraling, white oral arms and the 24 undulating maroon tentacles may trail behind as far as 3.6 to 4.6m (12 to 15 feet). For humans, its sting is often irritating, but rarely dangerous.
Chrysaora fuscescens has proven to be very popular for display at public aquariums due to their bright colors and relatively easy maintenance. It is possible to establish polyps and culture Chrysaora in captivity. When provided appropriate aquarium conditions, the medusae do well under captive conditions.
Chrysaora fuscescens is capable of both sexual reproduction in the medusa stage and asexual reproduction in the polyp stage. The life cycle of C. fuscescens begins when females catch sperm released by the males to fertilize the eggs she has produced and is holding in her mouth. These fertilized eggs remain attached to her oral arms, and there they grow into flat bean-shaped planula. Once they grow into flower-shaped polyps, they are released into the ocean where they attach themselves to a solid surface and undergo asexual reproduction. The polyp makes identical copies of itself this by means of budding, where the new polyp grows from its side. After the new polyp is fully formed, it too is released into the ocean and undergoes metamorphosis as it grows, developing a bell, arms, and tentacles until it is a fully formed medusa.
In common with other cnidaria, Chrysaora fuscescens are carnivorous animals. They catch their prey by means of cnidocyst (or nematocyst) -laden tentacles that hang down in the water. The toxins in their nematocysts are effective against both their prey and humans, though it is typically nonlethal to the latter. Because C. fuscescens cannot chase after their prey, they must eat as they drift. By spreading out their tentacles like a large net, the sea nettle is able to catch food as it passes by. When prey brushes up against the tentacles, thousands of nematocysts are released, launching barbed stingers which release a paralyzing toxin into the quarry. The oral arms begin digestion as they transport the prey into the sea nettle�s mouth.[3]
C. fuscescens feeds on a wide variety of zooplankton, crustaceans, salps, pelagic snails, small fish as well as their eggs and larvae, and other jellyfish. Due to their growing numbers, they seem to be reducing fish populations and have become nuisances to the fisherman of Oregon by clogging up fishing nets. Their dense swarms have also become problematic for scientific trawls and water intake.
Despite having a potent sting, Chrysaora fuscescens is prey to many marine birds and large fish.[
