invertebrate
Baby jellyfish are invertebrates, and their life span is very short, usually from 6 months to a year.
Can't leave water
Jellyfish, like fish, cannot leave water. Once out of water, they will die immediately.
Produce blisters
After the sun shines, jellyfish will produce blisters, just like fish in water.
Matters needing attention in aquaculture
The jellyfish raised at home have no light and live for a short time. If you keep a small jellyfish at home, it is likely to shorten its life. If you touch the small jellyfish directly with your hands, you may be in danger of poisoning.
Live on seaweed
Because jellyfish live in water mainly by nutrients secreted by algae, this nutrient is not available in the market.
Venom danger
There used to be a jellyfish baby who released venom to hurt people. It's often mentioned now. The thing is, a family keeps several jellyfish babies in the aquarium. Later, when people were sightseeing, they frightened the baby jellyfish and released venom. Many people who have been exposed to jellyfish babies have been poisoned to the hospital for treatment.
