Yes this is a proof: when corals grow another coral is probably growing in the way the other one is there they fight they digest each other and they also live because fire corals can hurt or sting
Yes, jellyfish, coral and anemones are of the Cnidarian Phylum. (aka Coelenterate ) these all have stinging cells known as nematocysts. =]
Organisms such as jellyfish, anemones, and some species of coral have tentacles with stinging cells called cnidocytes. These stinging cells are used for defense, predation, and capturing prey by injecting venom into their targets.
Coral is nor arthropod , sponge or echinoderm , A coral is a cnidarian also called a coelenterate because it possess cnidocytes , stinging cells , gastrovascular cavity ,tentacles which are cnidarian charters .
Small and light weight fishes such as zooplankton because there stinging cells are unable to grasp large prey.
The stinging cells in a jellyfish are located in it's tentacles.
Stinging cells are cells that "sting" and pour toxins into the bloodstream, and tentacles are long appendages that have no relation whatsoever to stinging cells.
Usually stinging cells belong to the phylum Cnidaria
Coral and Jellyfish are classified together because share characteristic such as radically symmetrical, simple net nervous system, distinct larva stage. The classification is the phylum Cnidaria.
Jellyfish, corals, and sea anemones are examples of organisms found in oceans that use stinging cells called cnidocytes to capture their prey. These cnidocytes contain specialized structures called nematocysts that inject toxins into their prey.
Stinging Cells
No, sponges do not have stinging cells like those found in cnidarians (e.g., jellyfish and sea anemones). Sponges are filter feeders that rely on water flow to capture food particles, rather than using stinging cells for prey capture.
The stinging cells in the hydra is what helps it paralyze its prey. Once it uses its stinging cells to paralyze it, the hydra then uses its tentacles to push into itsslef considering that its only one cell layer thin.
