Jellyfish and coral polyps are both species that are not bilaterally symmertrical, they are radially symmetrical, as are sea anemones which are also related to those species.
Closely related: obelia jellyfish Not closely related (but still related): coral sea anemone
Actually, echinoderms are more closely related to humans than molluscs.
Jellyfish are actually closely related to the Hydra. The greatest similarity between the two is that they both have a type of nervous system called a nerve net.
Jellyfish interact with a variety of organisms in their ecosystem, including fish that may prey on them, other jellyfish for competition and mating, and small planktonic organisms that they feed on. They also play a role in the food web by serving as both predator and prey for different species.
Group one (earthworm, spider, jellyfish) are more distantly related compared to group two (frog, trout, centipede) because group two share a more recent common ancestor. This is because frog, trout, and centipede are all part of the same phylum Chordata, whereas earthworm, spider, and jellyfish are part of different phyla (Annelida, Arthropoda, and Cnidaria, respectively).
Anemone.Please note that this is a riddle, not a biology question.An anemone is NOT a flower and it is NOT a plant. An anemone is an animal, and it closely related to jellyfish. (Imagine a jellyfish turned upside down: they both have spiral symmetry, stinging tentacles, and a "mouth" (sac gut) in the center). Search for "Cnidarians" to learn more about this group of animals.
There are no electric jellyfish and there are no jellyfish named that. You may be referring to many of the comb jellies that refract light into a brilliant display of moving rainbow colors along their comb rows by the waving of their cilia. In that case, the name of one of the most popular species (because it is prominently displayed at the Monterey Aquarium) is the Mertensia ovum, or 'sea nut' jelly. Unfortunately, even though comb jellies are gelatinous marine invertebrates, they aren't in the same order, class, or even phylum as jellyfish. Most comb jellies, and many hydromedusa (closely related to jellyfish), such as Aequorea victoria and Atolla wyvillei, do exhibit bioluminescence in the dark. But alas, no sea jellies can produce electric shocks.
The four major classes of medusozoan Cnidaria are:Scyphozoa are often called true jellyfish. They have tetra-radial symmetry. They have tentacles around the outer margin of the bowl-shaped bell, and oral arms around the mouth.Cubozoa (box jellyfish) have a box-shaped bell, and their velarium assists them to swim more quickly. Box jellyfish may be related more closely to "true jellyfish" than either are to hydrozoa.[35]Hydrozoa may form medusa which resemble scyphozoans (but generally with a velum) and are distinguished by an absence of cells in the mesoglea. However, many hydrozoa species do not form medusa at all (such as hydra, which is hence not considered a jellyfish).Staurozoa (stalked jellyfish) do not have a polyp stage, however the medusa is generally sessile, oriented upside down and with a stalk from the "bell" planted to the substrate. Until recently, staurozoa was classified within scyphozoa.
Because they are closely related
Because they all come from a wolf.
Fire corals are colonial marine organisms that look rather like real coral. Technically they are not corals, since they are more closely related to Hydra and other hydrozoans.
Yes; these are both wild reptiles, closely related to the rhinoceros, that roam the tall, purple jungles of the moon. They feed upon horseflies and the genitalia of martians. They have a mating dance very similar to "Gangnam Style" and are a highly endangered species because Canadians hunt them to eat on breakfast sandwiches. All in all, giraffes and jellyfish are wild, graceful creatures who should be protected by the EPA, but as of right now are unprotected. If you're still reading this, go back to preschool and learn the f**king difference.
