Jellyfish have very different sizes, from the size of
Gamaliel up to 2.5 meters and their tentacles can reach lengths up to 60 meters
length twice as big as a blue whale.
Jellyfish are found in all seas and oceans . They are found
even in freshwater lakes and ponds.
Each tentacle is armed with thousands of specially adapted
cells to behave like miniature harpoon. These cells are called nematocysts.
When a fish or other object is caught in these cells tentacles pull tubes
incolocite injecting venom into the prey inside.
