Latin name: Rhopilema esculenta
Common name: sea snake
Belongs to the phylum Coelenterata mantle jellyfish.
Morphological features:
The umbrella body is hemispherical, and the diameter of the umbrella is generally 30-45 centimeters, and the larger ones can reach 1 meter. The outer umbrella is smooth, and the umbrella has 130-180 marginal petals. Body color varies greatly, mostly greenish blue, but also dark red or yellowish brown. The tentacles and appendages are white. Warm water, like to live in the estuary near, self-swimming ability is very small, often with the tide, wind direction, sea current and floating. It is more responsive to light and salinity of sea water, and usually rises to the surface in calm winds and waves or in the morning and evening, and sinks when it encounters storms and heavy rain or when the sunlight is too strong.
Life habits:
Jellyfish jellyfish in the ocean in the planktonic life, inhabiting the near-shore waters, especially inhabiting the estuary near the distribution area, the depth of water is generally 5 to 20 meters, sometimes up to 40 meters.
Breeding habits:
Jellyfish dioecious, sexually mature in the fall. The amount of eggs carried by an individual jellyfish is directly proportional to the size of the umbrella, and the amount of eggs carried by an individual can be up to 30 million, or up to 50 million.
Jellyfish
Jellyfish (see jelly) is a marine coelacanth, the jellyfish body is umbrella-shaped, the body is translucent, white, green or yellowish, jellyfish umbrella diameter can be more than 45 centimeters, the largest up to 1 meter of the giant, under the umbrella of the eight thickened (with shoulder) carpal base healing so that the mouth disappeared (replaced by the suction cups of the secondary mouth), the lower part of the mouth carpal with a number of rods and filaments tentacles, on the dense cnidocysts, and the mouth of the mouth of the jellyfish, the mouth of the jellyfish, and the mouth of the jellyfish, and the mouth of the jellyfish. The mouth is covered with dense stinging filamentous sacs that secrete venom. Its role is in touching small animals, can release venom paralyzed to make food. Jellyfish in the tropical, subtropical and temperate coastal are widely distributed, our habitual jellyfish have umbrella smooth mouth and wrist only filamentous body of edible jellyfish or both rod-shaped rods jellyfish, as well as umbrella with many small warts protruding yellow spot jellyfish.
The life cycle of the jellyfish passes through the main stages of fertilization, such as grafting to the aphid and then combining with a hydra-shaped larva to date the transverse body to date the butterfly body to date the adult jellyfish. In addition to the sexual reproduction process of fertilization in the body, the jellyfish's hydra larvae will also give birth to creeping roots to form foot sacs, and even the transverse body will continue to split into a number of discs, in order to asexual reproduction to greatly increase the number of its individuals
