Having Varieties: when there is multiple partners you have different varieties. These are the 13 advantages of technology. Polyp reproduction can be asexual by budding through the evagination of a circular are of tissue including the endoderm and ectoderm, or sexual by spawning following the release of pheromones. Both, advantages and disadvantages of sexual reproduction is the planula develops into a zygote then settles . Medusa: It reproduces sexually by gametes. Hanging downward from the centre is a stalklike structure, the manubrium, bearing the mouth at its tip. The difference between polyp and medusa relies upon motility and shape.

For example, the hydra has only a polyp stage, for example, whereas most hydrozoans have a biphasic (two-stage) life cycle that alternates between a sedentary polyp stage and a mobile, bell-shaped medusa stage. While polyp lack the presence of sense organs, medusa have photoreceptors and gravity-sensing statocytes. A primary polyp gives rise to a gonochoristic colony consisting of functionally specialized zooids including gastrozooids and gonozooids. Medusa, however, can only reproduce sexually, giving birth to medusa only. In other cnidarian classes such as Cubozoa or Rhizostomae, medusa are produced by the metamorphosis of the polyp. Timing. This post highlights the key differences between polyp and medusa, along with the comparison chart. The body wall of a polyp has an outer ectoderm layer and an inner endoderm layer. The lack of a circulatory system to move dissolved gases limits the thickness of the body wall, necessitating a non-living mesoglea between the layers. Medusae are individuals that appear more of an umbrella or bell shape, with the mouth and tentacles hanging down. Medusa has a bell-shaped body with hanging tentacles.
