Extreme Jellyfish
There are some 2,000 species of jellyfish. Some are tasty, others will kill you with the tap of a tentacle. Here are nine varieties that really stand out

Jellyfish thrive in all sorts of climes, but in 2007 scientists from the Woods Hole Oceanographic Institution and other organizations were surprised to find them congregating near the mouths of “black smokers,” undersea mineral chimneys that spew water as hot as 626 degrees Fahrenheit. The jellies, discovered off Costa Rica’s Pacific coast at a depth of 8,500 feet, are a distinctive pink color, somewhat reminiscent of boiled shrimp.

They are intoxicating to watch. I have a collection of abstract jellyfish photos from my recent trip to the Monterey Bay Aquarium, if you are interested: http://www.pathosphotos.com/archives/799

Eduardo,
the common name of any species is actually the opposite of taxonomy. Squabbling over common names is not only not taxonomical, it's not even biology. Yet, to get to know and truly appreciate any species one must start with its taxonomical designation.
As for getting lost in taxonomy, one can certainly spend too much time on it but the notion of getting lost in an academic space that is essentially a living map for the rest of biologists to start their own scientific investigations is total nonsense! ;D

Don't get lost in taxonomy, Just let your eyes enjoy the beauty and embrace the moment. Look at the beautiful box jelly , but don't touch, then of course reality will come crashing into your life. Let your imagination loose, with great care of course, as with all life , The most brightly colored and beautiful packs the most punch.

Check the Oxford English Dictionary--historically, any animal living in the water has been called a "fish." Narrowing (or broadening for that matter) words' meanings is a well-known mechanism for linguistic change. Think of Shakespeare's usage King Lear: "...but rats and mice and such small deer [from German 'tier,' 'animal'] have been Tom's food for many a long year." It changes little by little, of course, not all at once one bright morning. Fasten your seatbelts, folks, English is alive!

I would have liked some size indication on most of these, that don't have something else in the picture. But great photos!

A rose is a rose is a rose, ETC!
Changing accepted names & terms is usually asinine.
For example, why was cycles-per-second
'CPS' -- [electronics] changed to "Hertz"? I refuse to knuckle-under to someone's whim . . . . . . .

A rose by any other name would still smell as sweet... a Sea Jelly or a "Jellyfish" still makes for a lousy vacation when you're trying to swim at the beach!!!

Jan, if your point is that they are not fish you may as well point out that they are not made of Jelly either!!

Jan, misnomers happen. Take the Orca which has been named a killer whale although technically a dolphin, and insects dubbed bugs although they are not (bugs being a selection of insects having sucking mouth parts).
JellyFISH are ace!

Jan: medusozoa and echinoderms, surely?

In response to Jan Williams:
If you mentioned a "Cod fish" in any country other than America, people would laugh at you. Here in England they are simply "Cod". Likewise, "Sea Jelly" and "Sea Star" are equally as alien, and as names sound very childish. In what way is jelly any more scientifically correct than fish?
My point is that common naming traditions are hardly inaccurate. Americans are in the minority with their names for these animals, which to me are inaccurate and non-descriptive. What's in a name anyway?

@Jan Williams:
Yeah, but...what if they don't live in the sea? Eh? What THEN?
