Jellyfish live in oceans and seas around the world. They are free-swimming marine animals that consist of an umbrella-shaped bell and trailing tentacles. Jellyfish go through different life stages from eggs to larval planulae to polyps and then to adult jellyfish. They are carnivorous and feed on plankton, small fish, and other jellyfish. While most jellyfish are small, some like the Lion's Mane can have tentacles over 30 meters long. Certain jellyfish like the sea wasp have venom powerful enough to kill a human within minutes.

2.  The jelly fish live in all ocean and seas over
the world.
 It’s an aquatic
animal.

3.  It is a free-swimming marine animal
consisting of a gelatinous umbrella-shaped
bell and trailing tentacles.

4. Eggs develop into ¨larval planulae¨, become
polyps, bud into ephyrae and then transform into
adult jelly fish.

5.  Most jellyfish do not have specialized
digestive, central nervous, respiratory, or
circulatory systems.

7.  Jellies are carnivorous, feeding on plankton,
crustaceans, fish eggs, small fish and other
jellyfish

8.  The smallest jellyfish have bell disks from
0.5 mm with short tentacles that extend out
beyond.
 The Lion's mane jellyfish was long-cited as
the largest jellyfish, and arguably the longest
animal in the world, with fine, thread-like
tentacles that may extend up to 36 metres
long

11. The sea wasp, a box
jellyfish found in
Australian waters, can
kill an adult human
within a few minutes.
Contact with a jellyfish tentacle can inject venom,
yet only some species' venom cause an adverse
reaction in humans.
