Answer:
They are composed of three layers: an outer layer, called the epidermis; a middle layer made of a thick, elastic, jelly-like substance called mesoglea; and an inner layer, called the gastrodermis. An elementary nervous system, or nerve net, allows jellyfish to smell, detect light, and respond to other stimuli.
Jellyfish don't go after humans, but someone who swims up against or touches one — or even steps on a dead one — can be stung all the same. ... But stings from some types of jellyfish — such as the box jellyfish (also called sea wasp) — are very dangerous, and can even be deadly.
Jellyfish have tiny stinging cells in their tentacles to stun or paralyze their prey before they eat them. Inside their bell-shaped body is an opening that is its mouth. They eat and discard waste from this opening. ... Tentacles hang down from the smooth baglike body and sting their prey.
They are food for a number of marine animals such as large fish and turtles. Even humans eat jellyfish – yummy! Jellyfish also provide habitat for many juvenile fishes in areas where there are not many places to hide. They can also protect the small fish from being eaten by predators with their stinging cells.
After a while and looking at my watch's timer, I blurted out to the group: “48 minutes.” Now we learned that jellyfishes could survive that long out of sea water.
