There is some misunderstanding that the case of the lighthouse jellyfish is not one of immortality, but one that should theoretically be immortal. The lighthouse jellyfish is only 4-5mm in diameter, which is very small. The body is transparent, the red stomach inside is visible at a glance, and their genome is very simple. They are carnivores and feed on plankton, crustaceans, polychaetes and small fish. By sexually reproducing by shooting sperm into the sea, the jellyfish has the opportunity to reproduce. In addition, it can transform into polyps (i.e., babies) to reproduce asexually, which is known as rearing.

2. What if I get stung by a lighthouse jellyfish?

(2) Rinse with seawater:Rinsing the stinging area with seawater again can inhibit the activity of the undischarged stinging cells on the skin, such as fresh water has the opposite effect. Any move that alters the balance of solution salt concentration inside and outside the stinging cells may stimulate the stinging sacs to discharge and release more venom.
