The bell can pulsate to acquire propulsion and locomotion. The tentacles may be utilized to capture prey or defend against predators by emitting toxins in a painful sting.]]> 2018-01-14 11:59:30 UTC https://padlet.com/zagalillo27/bzdrp8xf3oj8/wish/221247449 zagalillo27 https://padlet.com/zagalillo27/bzdrp8xf3oj8/wish/221247924 2018-01-14 12:05:03 UTC https://padlet.com/zagalillo27/bzdrp8xf3oj8/wish/221247924 zagalillo27 https://padlet.com/zagalillo27/bzdrp8xf3oj8/wish/221248400 In 1961, a japanese scientist extracted green fluorescent protein and another bioluminescent protein from the large and abundant hydromedusa , while studying photoproteins that cause bioluminescence in this species. Three decades later, another scientist sequenced and cloned the gene for green fluorescent protein.]]> 2018-01-14 12:11:27 UTC https://padlet.com/zagalillo27/bzdrp8xf3oj8/wish/221248400 zagalillo27 https://padlet.com/zagalillo27/bzdrp8xf3oj8/wish/221248678 https://en.wikipedia.org/wiki/Jellyfish#Ecology

The colonies of the colonial species can be large, and in some cases the specialized individual animals cannot survive outside the colony.]]> 2018-01-22 17:07:55 UTC https://padlet.com/zagalillo27/bzdrp8xf3oj8/wish/223436893 zagalillo27 https://padlet.com/zagalillo27/bzdrp8xf3oj8/wish/223446201 Jellyfish reproduction involves several different stages. In the adult, or medusa, stage of a jellyfish, they can reproduce sexually by releasing sperm and eggs into the water, forming a planula. In this larval stage of jellyfish life, the planula hooks on to the bottom of a smooth rock or other structure and grows into another stage of jellyfish life, the polyp--which resembles a miniature sea anemone. During this stage, which can last for several months or years, asexual reproduction occurs]]> 2018-01-22 17:26:23 UTC https://padlet.com/zagalillo27/bzdrp8xf3oj8/wish/223446201 zagalillo27 https://padlet.com/zagalillo27/bzdrp8xf3oj8/wish/223450978 Eating dried jellyfish is highly nutritious and they contain a lot of good substances. Jellyfish are one of Asia's most popular foods and are served dried and chopped into small pieces and boiled to add a crunchy texture and remove salt. Their health benefits are that they contain a lot of calcium binding proteins which improve memory and help to fight age related cognitive decline.]]> 2018-01-22 17:35:41 UTC https://padlet.com/zagalillo27/bzdrp8xf3oj8/wish/223450978 zagalillo27 https://padlet.com/zagalillo27/bzdrp8xf3oj8/wish/223463934 Jellyfish do not have a specialized digestive system. Food goes into the Jellyfish through the mouth which is found in the middle of the bell. Then, the food is trapped in the gastrovascular cavity and the nutrients are absorbed by the gastrodermis. The waste products also leave through the mouth. Jellyfish are carnivores and they feed on zooplankton and other jellyfish. Jellyfish poison the food they are about to capture with their tentacles. ]]> 2018-01-22 17:56:58 UTC https://padlet.com/zagalillo27/bzdrp8xf3oj8/wish/223463934 zagalillo27 https://padlet.com/zagalillo27/bzdrp8xf3oj8/wish/264274051 Jellyfish are such a unique kind of marine animal that they actually don´t have a circulatory system.They don´t even have a specialized respiratory system or nervus system.They can easily absorb oxigen when needed throgh their bodies.]]> 2018-05-29 14:41:42 UTC https://padlet.com/zagalillo27/bzdrp8xf3oj8/wish/264274051
