  1. Jellyfish

    Jellyfish and sea jellies are the informal common names given to the medusa-phase of certain gelatinous members of the subphylum Medusozoa, a major part of the phylum Cnidaria. Jellyfish are mainly free-swimming marine animals with umbrella-shaped bells and trailing tentacles, although a few are anchored to the seabed by stalks rather than being mobile. The bell can pulsate to provide propulsion for highly efficient locomotion. The tentacles are armed with stinging cells and may be used to capture prey and defend against predators. Jellyfish have a complex life cycle; the medusa is normally the sexual phase, which produces planula larvae that disperse widely and enter a sedentary polyp phase before reaching sexual maturity. Jellyfish are found all over the world, from surface waters to the deep sea. Scyphozoans (the "true jellyfish") are exclusively marine, but some hydrozoans with a similar appearance live in freshwater. Large, often colorful, jellyfish are common in coastal zones worldwide. The medusae of most species are fast-growing, and mature within a few months then die soon after breeding, but the polyp stage, attached to the seabed, may be much more long-lived. Jellyfish have been in existence for at least 500 million years, and possibly 700 million years or more, making them the oldest multi-organ animal group.Jellyfish are eaten by humans in certain cultures. They are considered a delicacy in some Asian countries, where species in the Rhizostomae order are pressed and salted to remove excess water. Australian researchers have described them as a "perfect food", sustainable, and protein-rich but relatively low in food energy.They are also used in research, where the green fluorescent protein used by some species to cause bioluminescence has been adapted as a fluorescent marker for genes inserted into other cells or organisms. The stinging cells used by jellyfish to subdue their prey can injure humans. Thousands of swimmers worldwide are stung every year, with effects ranging from mild discomfort to serious injury or even death. When conditions are favourable, jellyfish can form vast swarms, which can be responsible for damage to fishing gear by filling fishing nets, and sometimes clog the cooling systems of power and desalination plants which draw their water from the sea.


  1. jellyfish

    A jellyfish is a free-swimming marine animal with a gelatinous, umbrella-shaped bell and trailing tentacles. These tentacles are typically used for catching prey and are capable of stinging for defence or feeding. Their body is composed of a soft, delicate structure and they lack structures such as bones, brain, and heart. They are found in every ocean, from the surface to the deep sea. Some jellyfish even live in freshwater.-

Webster Dictionary

    Social shopping site jellyfish offers a radically new approach to shopping.On the surface, jellyfish appears to be a product search engine that returns lists of rebated items from sellers, ranked according to price, showing buyers the full price of items including the rebate provided by the sellerBut it is jellyfish’s business model that sets them apart from all the other fish in the sea (sorry for the pun): jellyfish’s model is very similar to affiliate ads - a referral fee is paid whenever an item is sold through the site. However, in this case the payment doesn’t go to a webmaster for referring the sale - it goes straight to the consumer. In fact, Jellyfish shares at least 50% of the commission with the buyer. In addition, advertisers are ranked by how much they’ll pay the customer for buying their product; these discounts can be as high as 24%. There are various online (social) shopping networks; some include: Kaboodle, Zlio, MyPickList, Wists, and Ideeli.

    Jellyfish have existed for over 500 million years, and over that time, their body structure has remained largely unchanged, so it's interesting to figure out what makes them so special and how we can learn from them, because we use animals with natural swimming motions, the hope is that they won't disturb the environment in the same way that a submarine might, so we can expand the types of environments we can monitor.
