What are the two basic forms of cnidarians?
Hydra - the polyp, anchored with a stalk, tentacles up; and medusa, the jellyfish, swimming free, tentacles down. All cnidarians have both stages, like larva and adult, but they spend more time in one of them and are known as that stage, for example anemones and jellyfish. Anemones have a tiny jellyfish dispersal stage, and jellyfish have a tiny polyp reproduction stage.

Where can you buy freshwater jellyfish for a fishtank?
No where readily available unless your Looking to spend a good amount of money on a New Aquarium (which is designed Specifically for them), Specific foods and then the Jelly it's self.What you are looking for is a Craspedacusta sowerbyi which is a freshwater jellyfish in the phylum Cnidaria. Since it is classified as a hydrozoan, it is one of many jellyfish that are also known as hydromedusae ("medusa" is another word for jellyfish).The dedication it takes to Keep a Jelly Alive and in good shape is something I suggest for only Pro's as there is more to keeping it alive then dumbing it in a tank and hoping for the best.But if you do happen to get one I wish you the best. I have always wanted one but I do not have the time to invest but Love reading about anything having to do with Jellies.
Where do most rainbow jellyfish live?
Crystal jellyfish live offshore and near shore in the sea. They will spend the better part of their lives in their plankton.
Where does Medusa spend her time at?
She spent some times in earth and some at Athena's temple because she was a priestess
What are cnidaria characteristics?
The characteristics of cnidarians are that they have claws, hard exoskeleton, and reproduce sexually. ------- That answer is just silly. The phylum, cnidaria, includes hydras, jellyfish, sea anemones, and corals. Cnidarians are defined by the fact that they possess cnidocytes (cells that can either attach or sting) which are often used to grab and immobilize prey, as well as for defense and in rare cases, for locomotion. Cnidarians are diblastic (two layers of cells), with a secreted layer between the inner and outer layer of cells, called the mesoglea. They possess a single gastrovacscular cavity that serves to respirate, disgest, and discharge waste. Commonly, tentacles surround the gastrovascular opening. Cnidarians are predominately radially or bi-radially symmetric. The two common forms of cnidarians are a polyp form (attached, vase-shaped), and a medusa (bell shaped, free swimming) form. Some cnidarians are exclusively sessile (attached to a substrate), exclusively free swimming, or include both forms during their life cycle.
Where does medusa spend most of her time in the myths?
With her sisters, the Gorgons. Medusa and the Gorgons were also related to the Fates but the Gorgons were half reptile and half human. She also had her head cut off by Perseus, so the only place she was really spending time after that was dead on the floor with Perseus carrying around her head like some sort of trophy.
Do jellyfish think?
Depends on how you define consciousness. If you define it as awareness of one's own existence then no, they do not, because you need a brain to produce such thoughts. However, they can successfully survive based on cellular memory.
How do you get Medusa's blood on Horse?
you might get one in a horn of plenty which costs 1 pass in the black market or for 1 pass in the black marketbut either way you have to spend one pass to get it, unless a friend who has one sends it to you as a gift
What reason are cnidoblasts important to the hydra?
A genus of small, freshwater cnidarians (coelenterates) which belong to the class Hydrozoa. Hydra is an exceptional member of this class because it is a mobile individual polyp rather than a sessile or colonial form, and uses its cnidoblasts to capture prey. Unlike most Hydrozoa, which spend at least part of their lives in a medusa form, which reproduces sexually, Hydra exists only as polyps. They are typically a few millimeters long.
How is a jellyfish and a kangaroo different?
There are many differences between jellyfish and kangaroos.A kangaroo is a warm-blooded vertebrate, a mammal that lives on the land. A jellyfish is an invertebrate sea creature, a coelenterate which must spend all its time in water in order to survive.Kangaroos have a full respiratory system by which they breathe, using lungs, trachea, nose and mouth, etc. jellyfish breathe by absorbing oxygen and releasing carbon dioxide through their outer surface.Kangaroos are marsupials, reproducing sexually, and giving birth to live young which then continue their development in the mother's pouch, nourished by mothers' milk. Jellyfish reproduce by releasing sperm and eggs into the water; these attach to a surface where they develop into polyps, and from this point asexual reproduction occurs, with the polyps developing into another form, the ephyra, which eventually become mature jellyfish.Kangaroos are grazing animals, feeding primarily on grasses and plant shoots; jellyfish drift, catching their food via their tentacles, or sometimes pursuing prey.
