1. Are all jellyfish dangerous to humans?

Answer: Not all jellyfish are dangerous to humans. However, some species of jellyfish have a potent sting that can cause pain, swelling, and even death in some cases. It’s important to be aware of the jellyfish species in your area and take necessary precautions when swimming or diving.

2. How do jellyfish reproduce?

Answer: Jellyfish have a complex life cycle that involves both sexual and asexual reproduction. In sexual reproduction, males release sperm into the water, which fertilizes the eggs released by the female. In asexual reproduction, the jellyfish can produce clones of themselves through a process called budding, where new individuals develop from a parent body.

3. What is the ecological role of jellyfish in the marine ecosystem?

Answer: Jellyfish play an important role in marine ecosystems as both predator and prey. They are a food source for many marine animals, including fish, turtles, and birds. At the same time, they also feed on zooplankton and small fish, helping to control their populations. Some species of jellyfish have been known to cause disruptions to ecosystems when they undergo population booms, as they can outcompete other species for resources.
