What are the characteristics of jellyfish in the ocean, introduction and characteristics of jellyfis

<>1. Introduction: Jellyfish is an important plankton in the aquatic environment.

Including cninophiliates.

Bowl jellyfish, cross jellyfish, cubic jellyfish. The jellyfish is a very beautiful aquatic animal, its body shape is like a transparent umbrella, the diameter of the umbrella body is large and small, and there are some whisker-like tentacles on the edge. Jellyfish have been around since 650 million years ago, and they predate the dinosaurs.

2. Features: no spine, relying on the buoyancy of water to support the body; There is a small ball on the thin handle in the middle of the tentacle with a small listening stone, which is the ear of a jellyfish; Body hydration.

Up to 98%, eating, digestion, and excretion must be completed in water.

Introduction: Jellyfish are important migratory organisms in the aquatic environment.

Features: No spine, body supported by the buoyancy of water; There is a ball on the thin handle between the tentacles.

Jellyfish are tentacles, soft-bodied, free-hunting animals with stinging cells, and mostly live in the sea. Cnidocytes have a type of cell in the body of coelenterates called cnidyl cells. The cnabsite cell has a nucleus and an outward-facing stalk, and contains a cyst-like spike cell with curled, elongated, hollow spikes.

When the stinger handle touches an animal outside, the curled barbed wire immediately pops out, piercing the other animal and releasing toxins, anesthetizing or killing the stabbed animal.

This is indeed a creature in the sea, different types of jellyfish, their living habits are different, some like to live in the deep sea, some like to live in a darker environment.

Jellyfish are creatures of the sea, and generally speaking, jellyfish like to forage at night and will glow at night.

There are more than 250 known species of jellyfish in the world, and fluorescein is contained in the jellyfish.

and luciferases, which emit light when they pass through the ocean catalyzed by oxygen. There are many organisms that can emit light in nature, such as fireflies and jellyfish. Jellyfish are amazing creatures because their bodies are transparent, and their bodies are able to emit different colors of light in the deep sea, which is very beautiful.

There are many types of jellyfish, and basically every jellyfish can emit light, especially the light emitted by many jellyfish is very beautiful. Many people are curious about why jellyfish emit light? <>

After research, many scientists have found that animals generally emit light because their bodies contain more luciferase and fluorescein, which can emit light after being catalyzed by oxygen. But the reason why jellyfish can emit light is not only because of fluorescein and fluorescence, but also because they have a luminescent system in their body, called the wonderful protein of Equeline. That is, the greater the number of Equeline proteins in the jellyfish's body, the brighter the light they emit.

Different jellyfish have different amounts of Equiline protein in their bodies, so this also causes different light emitted by the mind, some jellyfish emit a blue shimmer, some jellyfish have a pale green light, some jellyfish have purple light, and some jellyfish can even emit rainbow colors.

When they swim in the deep sea, they will be like a ball of light in the deep sea, adding a lot of mystery to the sea. Jellyfish emit light in order to attract prey in the deep sea, and these prey are attracted by the light emitted by the jellyfish, and the jellyfish only need to wait in place for the prey to come to the door automatically. <>

Although jellyfish are very beautiful, you must not hunt at will, because some jellyfish can generate electricity, and if you hunt without permission, you are likely to be electrocuted. Because jellyfish are very beautiful, there are also companies that use jellyfish corpses to make a jellyfish lamp, which can emit a very beautiful light without electricity.

There are more than 250 species of jellyfish. Because jellyfish have a light-emitting protein in their body, and jellyfish rely on this protein to emit light.

There are many types of jellyfish, there are nearly 250 species, and jellyfish emit light because of the presence of a fluorescein in the body, which reacts to produce light.

There are about 250 of them. Because these organisms contain some anorectal pigment in their bodies, this element will light up when it gathers in large quantities in the body of the organisms.

After installing the jellyfish tank according to the instructions and soaking the tank, add seawater, natural seawater needs to add jellyfish protectant, and it needs to be precipitated for about 24 hours before use, and artificial seawater is added to the proportion of artificial sea salt in pure water (do not add edible salt, seawater salinity.

Generally for the sea elf, many people want to raise but because the jellyfish is poisonous to it is discouraged, if stung by the jellyfish, there may be symptoms such as redness or muscle pain in a short period of time, and in severe cases, there will be difficulty breathing.

Shock and even death.

<>So what kind of jellyfish should we pick? The reason for the lack of water flow at all, you can change the water in a small amount and wash down the small jellyfish with the water flow, and the small jellyfish will swim, but it should be noted that the temperature of the water bought back or the salinized water and the water in the jellyfish bottle should not be too different, otherwise the small jellyfish will be very uncomfortable and even die. The living temperature of the mother is 20-33, and the optimal breeding temperature is between 22-26, and the water temperature is usually below 28; The survival temperature of colored jellyfish is 20-36.

The optimal breeding temperature is between 22 and 26, and it is usually necessary to ensure that the water temperature is below 32. Moon jellyfish.

It is also a good choice, they are relatively less toxic than other jellyfish, they like to live in a 25 degree water, they have high requirements for food, for people who want to start the sea moon jellyfish, I will tell you how to raise it by loving the pet network, but the jellyfish bottle should be kept in the refrigerator and freezer; If you want to watch it, take it out again, don't watch it, continue to put it back in the refrigerator, the temperature is too high, and the jellyfish are easy to die. Then configure the water exchange salt. Because the jellyfish will not adapt to the new seawater, it is necessary to prepare the seawater first and change the water of the jellyfish later.

Usually put the jellyfish bottle in the refrigerator and keep it; If you want to watch it, take it out again, don't watch it, continue to put it back in the refrigerator, the temperature is too high, and the jellyfish are easy to die. Then configure the water exchange salt. Because the jellyfish will not adapt to the new seawater, it is necessary to prepare the seawater first and change the water of the jellyfish later.

Jellyfish are marine creatures, so they must be farmed with seawater. They also need to change their water every week or so to avoid dirt and microorganisms blocking the jellyfish and fish from receiving energy, which can affect their movement speed. Be careful not to touch jellyfish when changing the water. Don't rush when adding water.

Jellyfish should be kept in a relatively large fish tank, the water in the fish tank should be changed frequently, and there should be enough oxygen, and a few small fish should be put in it.

Jellyfish are marine creatures, so they should be kept with seawater. Generally speaking, the water must be changed when raising jellyfish, and it can be changed for 1 3 weeks of water. This is to avoid contaminants in the water blocking the jellyfish's receptivity and also affecting the jellyfish's swimming speed.

It is possible to buy a special aquarium to raise jellyfish and install a thermostat. The temperature can be adjusted to about 25 degrees.

Jellyfish are characterized by being 98 percent water.

It's probably more transparent.

Jellyfish are a very beautiful aquatic animal. Although it does not have a backbone, it has a very large body, which mainly relies on the buoyancy of water to support its huge body. The body of the jellyfish is shaped like a transparent umbrella, and the diameter of the umbrella body can be large and small, and the diameter of the umbrella body of the large jellyfish can reach 2 meters.

From the edge of the umbrella grows some whisker-like bands, which are called tentacles, and some tentacles can be up to 20 meters to 30 meters long, which is equivalent to the length of a large whale. Jellyfish floating in the water have long tentacles stretched out in all directions, and some jellyfish have umbrella-like bodies with various color patterns. In the blue ocean, these jellyfish of different colors swim beautifully.

The tentacles of jellyfish are covered with stinging cells, like small beans stuck to the tentacles. These stinging cells shoot poisonous filaments that scare away or poison the "enemy" when it encounters its prey.

Jellyfish Physical characteristics Looks like an umbrella, the edge of the umbrella has many tentacles, the mouth is located on the ventral side**, some have a long mouth tube, or have a long mouth wrist. It can be divided into two categories: small hydroid jellyfish and large bowl jellyfish. Jellyfish belong to the phylum Coelenterate, the class Bowls.

The body of a jellyfish is made up of an umbrella-like gelatinous substance. There are many tentacles underneath, and with the help of muscle contraction inside the umbrella, jellyfish can swim together on the surface of the sea. Due to its in vivo.
