Strange friends you have never seen jely fish

Jellyfishandsea jelliesare the informal common names given to the medusa-phase of certain gelatinous members of thesubphylumMedusozoa, a major part of thephylumCnidaria. Jellyfish are mainly free-swimming marineanimalswith umbrella-shaped bells and trailingtentacles, although a few are anchored to the seabed by stalks rather than being mobile. The bell can pulsate to provide propulsion for highly efficientlocomotion. The tentacles are armed withstinging cellsand may be used to capture prey and defend against predators. Jellyfish have a complexlife cycle; the medusa is normally the sexual phase, which producesplanulalarva that disperse widely and enter a sedentarypolypphase before reaching sexual maturity.
