Abstract
The paper discusses the life-cycle and reproduction, defense and feeding mechanisms and body systems of jellyfish. The paper looks at how they group themselves into "swarms" or "blooms" and the problems when keeping them in captivity. The paper discusses the severity of jellyfish stings and the different species of jellyfish that exist.
Outline:
Life-cycle and reproduction
Defense and Feeding Mechanisms
Body Systems
Blooms and Grouping

Species
From the Paper
"Jellyfish are marine invertebrates which are part of the Scyphozoan class, and in turn the phylum Cnidaria; "members of this structurally simple marine group possess one of two body forms. Sea anemones, sea whips, corals and hydroids are polyps growing attached to rocks or other hard surfaces of the sea. Jellyfish and the Portuguese man-of- war are free-swimming medusa. Both body forms display radial symmetry with body parts radiating from a central axis. This symmetry allows jellyfish to respond to food or danger from any direction" . Moreover, they have strange shapes and colors: they might look like a bell or an inverted bowl from 3 millimeters to 2 meters in diameter. Their bells contain small sense organs that respond to light and gravity."

Abstract
This paper proposes a jellyfish living at 3,000 feet below the surface of the sea. It describes the key functions of this jellyfish, including procreation, locomotion, fight or flight, courtship, distance (smell) and touch (taste) reception. The paper concludes that the jellyfish described in the paper is able to combine most of the senses, locomotory impulses, sexual behavior and eating of more sophisticated organisms with a fairly straightforward and primitive nerve system. The paper includes an image of the jellyfish, several illustrations, and a table.
Outline:
Introduction
Primary Morphology of the jellyfish
Morphology of the Jellyfish
Anatomy of Major Cell Groups
Muscle Cells
Eyes
Skeletal Cells
Tentacles
Feeding, Locomotion, Courtship, Fight or Flight
Nerve Action: Smell
Central Nervous System Morphology
Proprioceptive Nerve Impulses
Vision Nervous Response and Courtship/Mating
Feeding and Satiety
Locomotion Detection
Conclusion
Bibliography
From the Paper
"When the jellyfish tentacles touch a body, sense (taste) elements determine if it is food or a predator. It will sting whatever it comes in contact with; the chemicals in the poison are predigestion chemicals, which combine with the cells of the stung creature in a way that breaks cell membranes and releases chemicals which the sensory (taste) bundles in the tips of the tentacles can use to determine if the creature is food or a predator. In the case of a predator, the jellyfish will not activate the "bring to stomach" mode; in the case of food, the jellyfish activates muscles which cause contraction of the tentacles, which are attached to the prey via the physical hooks of the stingers. The default is "food," in which case poison darts are injected and the food is pulled up to the gut. The morphology of the tentacles is such that, by contracting, the tentacles automatically move towards the gut in a coordinated fashion."
