The process of replacing stinging cells in animals, such as jellyfish or sea anemones, can vary depending on the species and the individual animal's health. In general, it can take a few days to several weeks for these animals to replenish their stinging cells after they have been used and discarded. However, some species have continuous regeneration, allowing them to replace their stinging cells more rapidly.
