1. Basic introduction to jellyfish

1. Distribution of jellyfish

Jellyfish are important plankton in aquatic environments, also known as sea blubber. More than 250 species of jellyfish are currently known, most of which are commonly found in the ocean, with only a few species occurring in freshwater. So basically their traces can be found in tropical waters, temperate waters, shallow-water zones, oceans about a hundred meters deep, and even freshwater areas.

2. Morphology of jellyfish

The jellyfish body is bell-shaped or shaped like an inverted bowl or umbrella. The outward-bulging side is called the exumbrella or upper umbrella surface, and the concave side is called the subumbrella. In the center of the subumbrella there is a downward-hanging tube called the manubrium, and the free end of the manubrium is the mouth. The edge of the umbrella has a ring of tentacles. In the jellyfish Gonionemus, the edge of the subumbrella extends inward as a narrow membranous structure called the velum, and most jellyfish have their radial canals, tentacles and sensory organs arranged in fourfold radial symmetry. In addition, jellyfish are not only variable in color, but also glow in the water, appearing pale green or blue-purple.

3. Toxicity of jellyfish

Jellyfish do have a certain toxicity, but generally when stung by a jellyfish you only feel a burning pain and develop redness and swelling. Still, do not worry: as long as you apply anti-inflammatory medicine or edible vinegar, the swelling and pain will subside in a few days. However, if breathing difficulties occur, artificial respiration should be given immediately or a cardiac stimulant injected, and the person should be taken to hospital promptly.

2. What food do pet jellyfish generally eat?

1. Jellyfish are beautiful and gentle in appearance, but they are indeed very fierce carnivorous animals, often feeding on plankton, small crustaceans, polychaetes and even small fish. When hunting, jellyfish usually extend their tentacles and release nematocysts to entangle, paralyze and poison their prey, then send the food into their mouths.

2. If you keep jellyfish at home, you can feed them brine shrimp, Artemia and other nutrient-rich organisms, all of which can be bought at aquariums, flower-bird-fish markets or online.

3. How should jellyfish be cared for?

If you like jellyfish and want to keep them, you must first master some knowledge of jellyfish breeding. Below is a brief introduction for beginners on how to keep jellyfish.

1. Jellyfish all have a certain toxicity, but choosing weakly toxic ones to keep is generally no problem. Even so, people with sensitive constitutions should still be careful about contact with jellyfish, because itching or redness and swelling can occur from contact.

2. Jellyfish generally live in the ocean, so seawater must be used to keep them. Generally, change the water about once a week, replacing one third each time, and when adding water for the jellyfish, add it slowly.

3. When buying jellyfish, the aquarium staff will generally give you a simple explanation. You can buy a special aquarium for jellyfish; in particular, an aquarium with a certain degree of water-flow control is best for keeping jellyfish.

4. Keep the temperature in the aquarium at around 25 degrees, and lighting should also be sufficient, though generally professional aquariums will be fitted with blue coral lights and a thermostat.

5. As mentioned above, jellyfish are fed on nutrient-rich organisms. When buying jellyfish, you can buy food at the same time, but each feeding must be controlled in amount. Generally, when the digestive organs and mouth in the jellyfish's bell turn orange, it means the jellyfish is already full, and at this point there is no need to feed more, otherwise it is easy to pollute the water quality in the aquarium.

The above is all the content introduced by Tuliu.com for everyone about what jellyfish eat and how to keep them. In addition, pet jellyfish have a lifespan of about 9 months, so everyone must be responsible for them when keeping them.
