Jellyfish (are
found) during the summer months in the water close to the shore and on
the beaches of the Mediterranean. For bathers, they are nasty creatures (whose)
sting can be painful. For beach-lovers, they area nuisance because they
rarely get washed up onto the beach where they die, leaving a terrible smell.
Jellyfish vary (widely) in their size and colour; they range from a few
millimeters across to six feet in diameter, with tentacles 100 feet long. Some
are extremely dangerous. An Australian species of jellyfish, called a sea wasp,
looks like a box and has the most deadly venom in the world in its sting. It (can)
kill a man very quickly. Jellyfish (have existed) for millions of years, and
scientists believe that they will survive (as long as) there are oceans on
earth. At a time of (disappearing) species and fear for our planet, jellyfish
continue to multiply. (Furthermore) there are species in the depths of the ocean
that we haven't even seen yet.
