These are all names for 
the same free-swimming marine animal.

The term jellyfish encompasses 
about 1500 species,
ranging in size 
from microscopic 
to more than 7 feet around
and 120 feet long.

Most jellyfish do not have 
a central nervous system.
Instead they have nerve nets
that sense changes in the 
environment, & then coordinate 
the jellyfish response to that.

They do not need respiratory organs 
such as lungs,
as they absorb their oxygen.

Jellyfish are made up of 92% water.

Because they have no ‘hard’ parts,
fossils are very rare.

They are considered to be 
the oldest multi-organ animal group.
Some people even believe
they lived before there were
dinosaurs!

They live from the surface of the water 
to the deepest water.

Imagine putting not quite 3 school buses 
in a line - end to front, etc.

That’s about how long their tentacles
can be - up to 120 feet!

Marine authorities still do not agree on what is a ‘true jellyfish’, what is plankton, or even if ‘that one’ is a jellyfish at all!

Jellyfish kill more people every year 
than sharks do.

provided several jellyfish photos)

Box jellyfish are considered the nasty jellyfish relative from out of town that 
no one in the family talks about.

They can be found in Northern Australia’s ocean & the Indo-Pacific region.

A sting from a Box Jellie tentacle 
can kill a person in 3 minutes.
It is not a pleasant way to die.

Each tentacle holds enough poison 
to kill 20 people.

Box jellyfish also have 24 eyes
!!!

All jellies produce some kind of toxin,
But
not all toxins affect humans.

Even after a jellyfish is dead, 
they can still give nasty stings.

Best choice?
Don’t touch any jellyfish with 
bare hands or skin.

Well, as always I have more information,
but I do not need to write a book!
Jellyfish are beautiful creatures,
with some really unique characteristics.
