Jellyfish
belong to the phylum Coelenterata. They are water-dwelling animals.
The name Coelenterata literally means hollow intestine and refers
to the central cavity of the animal. These animals are translucent
and gelatinous. They come in a variety of shapes, sizes and colors
and they all have long, dangling tentacles 
equipped
with stingers for obtaining food and fighting off predators.
Bathers and swimmers take note: The sting is poisonous and has
a paralyzing effect.
The Coelenterata is made up of four classes:
Hydrozoa, Scyphozoa, Anthozoa and Ctenophora. Jellyfish are found
in the Scyphozoan and Hydrozoan classes. Comb jellies and sea
walnuts have a superficial resemblance to jellyfish and are often
called jellyfish. They belong to the Ctenophoran class.
Jellyfish can be as small as 1/16 of an
inch across to over 6 feet. The Portuguese Man-of-War (Physalia
physalia) has tentacles up to 50 feet long. The By-the-wind Sailor
is about 2 to 4 inches wide with short tentacles
Species and individuals are most numerous
in warm tropic seas, but jellyfish can also be found in colder
waters; in fact, one of the larger medusae, Chrysaora, is found
in the North sea.
