Aurelia aurita also known as the Moon Jelly, are the most frequently recognized kind of jellyfish. They inhabit the Arctic, Atlantic, and Pacific Oceans along the shore. The moon jelly isn't very large, it varies in dimensions from 5cm to 40cm across. The animal has four lilac and pink half-moon shaped gonads underneath and in the middle of its semi-transparent bell. The bell is huskier in the center, diminishing towards the perimeter. Similar to other jellyfish, it has limited mobility, therefore the current of the ocean is its way of transportation. Moon Jellies have two primary stages in their life cycle. the polyp stage and the medusa stage. A fully developed polyp reproduces asexually. This is called budding, assembling a whole colony …show more content…
Polyps trained in reproduction make ephyra (small medusae) by budding. The medusae float off and grow. They then reproduce sexually. the sperm and the egg of two separate medusae produce a zygote.. The zygote turns into a planula (larva). The planula larva abandons the adult medusae. It then finds a shaded surface and adheres itself to it. The planula ultimately grows into a new polyp, and the life cycle of the Aurelia aurita begins once again.

Adult flukes deliver eggs in the biliary ducts of their hosts. The ducts transfer bile from the liver and gallbladder through the pancreas to the small intestine. The eggs arrive in the gallbladder and continue to the host’s abdomen when the gallbladder is discharged from the anus and released with the feces. One liver fluke can produce up to 25,000 eggs daily. Once away from the host, the larvae miracidia break out of the eggs. This take about 7 to 15 days. These larvae can persevere for multiple weeks off a host if afforded enough humidity. If their environment is too dry, they perish rapidly. Miracidia can swim and infiltrate into the snails where they stay for 4 to 8 weeks and evolve triumphantly into sporocysts, rediae, and
