differ by the length of the hydrocarbon chain, and if its saturated or unsaturated.
Sponges are invertebrate animals that usually have no body symmetry and never have tissues or organs. Cnidarians use stinging cells to capture food and defend themselves. Flatworms are flat and as soft as jelly. Unlike cnidarians or flatworms, roundworms have a digestive system that is like a tube, open at both ends. Earthworms and other segmented worms have bodies made up of many linked sections called segments.
how does it different from the families of other societies
They differ because one is cool and the other one is awesome
They differ from each other by the cognent that it is connected to.
There are four classes of cnidarians. Syphozoans, Hydrozoans, Cubozoans, and Anthozoans. Anthozoans don't have a medusa stage of life, so they don't get credit for being a jellyfish because they are never free swimming medusae. Syphozoans are considered by scientists to be a 'jellyfish', but the other two classes are considered jellies also (with reservations) because even though they have two layers of epithelial tissue with mesoglea (non-living gelatinous secretion) between the exodermal and the endodermal layers of 'skin', they are not radially symmetric. Other invertebrates of the gelatinous marine environment include the ctenophores and scalps. Scyphozoans are characterized by their radially symmetric, umbrella shaped bodies. Hydrozoans are characterized by their colony of polyps, which are not radially symmetric. Cubozoans are characterized by their four sided, roughly cubical shaped bodies. They are also characterized by their 24 eyes, ability to perceive their environment, and actively both evade predators and pursue prey. These guys are not drifters, like most of the members of the 'jellyfish' distinction.
Cnidarians aretypeof animals.They are heterotrophic. They feed on other animals
from other animals they get it
cnidarians move from place to place. sponges dont.
Nearly all corals and some other cnidarians are attached and are called sessile .
prawns, copepods, cnidarians, and other small inverdebrates.
Most cnidarians have tentacles with stinging cells surrounding their mouth. The mouth is the only body opening. All cnidarianshave radial symmetry.
They don't technically have a brain. Echinoderms have a simple radial nervous system with a nerve net, like in jellyfish but different. The nerve net has no central brain, although there may be ganglia present.
They're not, that I know of. They may be losing some of their habitat in some areas, but jellyfish, anenomes, coral and other of the invertebrates are thriving in other areas. The ones that i know are endangered are corals. They are being lost through bleaching, and dredging.
They are called pneumatocysts. They are the stinging cells used for killing prey, as all cnidarians are predators. They are cells that contain poison, and have little barbs on them to inject the poison with. With some cnidarians, the little barbs are all that you feel because their poison is only strong enough to kill plankton. With other cnidarians, however, the poison in the pneumatocysts is strong and can be deadly. The main purpose of the pneumatocysts is to kill prey, but they are also useful against predators.
how does the thai musical essemble differ from each other
fish, mollusks, worms, crustaceans, echinoderms, sponges, tunicates and other cnidarians
