Do Cnidarians replace their stinging cells once used?
Many people are familiar with the Jellyfish sting. When a jellyfish brushes against someone and they feel pain, they are feeling the cells along the jellyfish's tentacles referred to as cnidocytes. These cells harbor tiny projectiles full of venom, called nematocysts. There are many questions about the sting of the jellyfish, the structures involved, and the venom delivered. Specifically, do Cnidarians possess any capabilities of being able to replicate the stinging cells once they are used? Cnidarians are amongst the oldest known animals on Earth to possess a venom. Part of the reason their systems are so effective, and able to overcome animals of increased complexity, …show more content…
Everyone knows that a jellyfish can sting someone in the water. However, when analyzing the science behind the method as to how they sting it wouldn’t seem obvious that they are able to sting outside of the water. Yet, we know that jellyfish can sting outside of water, regardless if they are still living. Ultimately, the question can be posed, “How do jellyfish sting outside of water?”
There was once a story that came from a beach in New Hampshire where over 150 people were stung by something in the water. Additionally, five children were sent to a hospital after receiving injuries. When no one saw any sign of a jellyfish experts were called in. Initially, they thought it was a jellyfish bloom; yet, there was no sign of any individual jellyfish. They took samples, and found that while there were no live jellyfish around, there were thousands of broken apart tentacles drifting throughout the waters around the beach. Even more intriguing is that these tentacles all came from one individual …show more content…
Primarily, it reveals that the cnidae of a jellyfish act autonomously. Therefore, one can take the logical stance that any cnidae can operate independently, whether they are in the water or not. However, if it were to be out of the water wouldn’t this go against the osmotic-tension hypothesis?
Simply put, this does not discredit the osmotic- tension hypothesis. Firstly, experts who composed the hypothesis are not one hundred percent sure exactly how the process works. Furthermore, they state there is little known about it as a whole. Additionally, it can be deduced that the purpose of using a change in pressure to sting is not to actually deliver the sting itself, but rather to be able to accelerate it. Assuming that is true, Cnidarians do not need the osmotic pressure in order to deliver venom, only to accelerate the hollow tubules into the
