Craspedacusta of way. The first process is called

Craspedacusta Sowerbii, also known as a freshwater jellyfish, was first discovered in Regents Park, London in 1880. Craspedacusta Sowerbii is native in the Yangtze River valley in China and has earned the nickname ???, peach blossom fish. The freshwater jellyfish is a Hydrozoa class in the Limnomedusae order that belongs to the Olindiidae family. The freshwater jellyfish soon became worldwide around the 1900s due to human transportation of fish and aquatic plants. The freshwater jellyfish is considered not a “true jellyfish” by many scientist due to the presences of a velum and is not marine exclusive in habit nature, since it can be found in various bodies of water including freshwater lakes, man made impoundments, water filled quarries, streams, etc. There are two distinct forms of a Craspedacusta Sowerbii, a hydromedusa and polyploid form. A hydromedusa is usually very small, transparent, bell shaped with long and hollow tentacles that contain numerous stinging nematocysts for immobilizing prey. The hydromedusa has its body on top and tentacles hanging at the bottom. Whereas, a polyploids have their tentacles faced up and is typically more vase shaped. Polypoids and Hydromedusae are carnivores, they feed on zooplankton such as copepods, and other small organisms in the water, such as brine shrimp or Daphnia. Polyploids uses nematocysts that are located in its capitulum to immobilize prey, which allows them to consume prey that are many times its size. Hydromedusae also use nematocysts to immobilizing prey for large prey and are unable to activate the nematocyst for small prey due to the prey being too small or too slow. Freshwater jellyfish natural predators are crayfish, turtles and possibly geese and larger fish. Hydromedusae reproduce sexually. Males release all their sperm into the water and females release all their eggs, this process is called spawning. Fertilized eggs develop into free-swimming planula larvae which sink to the bottom of the water column and develop into polyps. Sexual reproduction is a rare occurrence is fresh water jellyfish. Polypoids reproduce asexually, which is expressed in the process of budding. Polypoids bud in three different types of way. The first process is called budding, this is when one organism grows off the main organism. The second process is called frustule budding, the frustule moves a short distance and attaches itself to a substrate in order to gain nourishment with the lack of a oral opening. Lastly, the budding of hydromedusa. The buds grow on until it is considerably larger than the polyp itself. It becomes a sexually immature medusae when it released into the water.
