Jellyfish are marine invertebrates belonging to the Scyphozoan class. The body of an adult jellyfish is composed of a bell-shaped, jelly producing substance enclosing its internal structure, from which the creature's tentacles are suspended. Each tentacle is covered with stinging cells (cnidocytes) that can sting or kill other animals: most jellyfish use them to secure prey or as a defense mechanism. Others, such as Rhizostomae, do not have tentacles at all. To compensate for its lack of basic sensory organs and a brain, the jellyfish exploits its nervous system and rhopalia to perceive stimuli, such as light or odor, and orchestrate expedient responses. In its adult form, it is composed of 94–98% water and can be found in every ocean in the world. Most jellyfish are passive drifters that feed on small fish and zooplankton that become caught in their tentacles. Jellyfish have an incomplete digestive system, meaning that the same orifice is used for both food intake and waste expulsion. They are made up of a layer of epidermis, gastrodermis, and a thick layer called mesoglea that produces most of the jelly and separates the epidermis from the gastrodermis.
Their shape is not hydrodynamic, which makes them slow swimmers but this is little hindrance as they feed on plankton, needing only to drift slowly through the water. It is more important for them that their movements create a current where the water (which contains their food) is being forced within reach of their tentacles. They accomplish this by rhythmically opening and closing their bell-like body.
Since jellyfish do not biologically qualify as actual "fish", the term "jellyfish" is considered a misnomer by some, who instead employ the names "jellies" or "sea jellies". The name "jellyfish" is also often used to denote either Hydrozoa or the box jellyfish, Cubozoa. The class name Scyphozoa comes from the Greek word skyphos, denoting a kind of drinking cup and alluding to the cup shape of the animal.Source(s): --- http://en.wikipedia.org/wiki/Jellyfish

It sounds like your basic pelagic Cnidarian, a sea jelly such as the Scyphozoa or Hydrozoa. 95% water, they have very soft bodies that do not last long out of the water. Many have stinging tentacles on the underside surrounding the single opening to their stomach cavity.
Though your description is pretty vague, they cough be salps, transparent , tube shaped organisms, chordates like us, for their larval form has a simple notochord like we do as embryos. Free floating filter feeders that often form colonies.
