Explore Stingers (Cnidarians)
This group of animals with a soft sac-like body and one opening surrounded by tentacles includes jellyfish, corals, and anemones. These animals are all carnivores capturing food using sticky tentacles lined with specialised stinging cells called nematocysts that fire venom laden harpoons into their prey on contact. The tentacles then draw the food into their body where it is digested before the remains are ejected.
Comb Jellies are including here because they are jelly like but are not actually in the same group at all. They are known as Ctenophores and are notable for the groups of rows of cilia they use for swimming that appear iridescent.
