According to wikipedia:
They are commonly but erroneously thought of as a jellyfish. In fact, a Portuguese Man O' War is not a single animal, but rather a siphonophore - a colony of four kinds of minute, highly modified individuals, which are specialized polyps and medusoids[1].
Actually, jellyfish eat whatever they can!
its actually jellyfish phobia... LOL
The box-jellyfish is special from all the other jelly-fish because, it doesn't drift but actually moves. All of the other jelly-fish just drift with the current, they are not moving. The box-jellyfish is actually not a jelly-fish. It is just called a jellyfish for its jellyfish appearance not for it truthfully being a jellyfish.
in a short answer, yes. try looking on youtube for tangled jellyfish to see what I mean. and some jellyfish actually eat each other.
Actually, there is no name for that phobia.
Yes actually jellyfish are descendents from the schishordizor species who have a direct line to the common centapide
No; only specific jellyfish are. Actually, quite a few people around the workd eat jellyfish. Although, I do not recommend getting a jellyfish and cooking it to eat without training and/or experience.
eather one they get to choose they can find food alone or together it's actually the jellyfish's choice.
a jellyfish is basically a plant like organism that does not actually shock it just gives a small sting from its tentacles
No 90 % water
The scientific name for Boxer Jellyfish is Stomolophus meleagris.
jelly's are actually camouflaged cos it's coloration.
