Reproductive strategy is described into r-selection strategy and K-selection strategy. When an organism reproduces slowly and has only one offspring each time it reproduces, this organism is classified as the K-selected organism. Examples of K-selected organisms are elephants and humans.
In medusae, mesoglea comprises the bulk of the animal and forms a resilient skeleton. In polyps, the water-filled coelenteron acts as a hydrostatic skeleton, which, in concert with the mesoglea, maintains the form of these animals. Muscles in cnidarians are extensions of the bases of ectodermal and endodermal cells.
