Meduza de mare

Jellyfish are some of the most delicate marine aquatic beings, they do not have bones, cartilage or shells, they are simply a living gelatinous mass with 95% water content, which most of the time amazes by simply cutting, where you also think that they swim and hunt, and even cause fatalities among people. These amazing creatures are desired by many aquarists, but they are sensitive and are only recommended to those experienced in marine aquaristics.

       Jellyfish kills their prey, or defends themselves by using nematocists, poisonous cells, these prey nettle cells, paralyzing it, and then jellyfish it to the mouth through the tentacles. Many people are jammed annually by jellyfish because it's not always easy to see them while swimming, many of them almost transparent.
Keeping jellyfish in the aquarium is not simple, they have special needs. In nature, they rely mainly on currents to move, to reach food and to remove metabolic products, and in the aquarium, it takes a certain stream and a filter strong enough to provide clean water but that does not aspire jellyfish and is recommended cylindrical or spherical aquariums because in the case of rectangular, jellyfish can remain stuck in the corners.

      The life cycle of the jellyfish is quite complex, reproducing both sexually and asexually. The life of a jellyfish begins when the male releases the sperm, which reaches the female cavity and fertilizes the ova (sexual reproduction), then they are released into the mass of water and deposited on the substrate where they will develop polyps. The polyps divide giving birth to new individuals (asexual reproduction) and they will release young jellyfish in the water. Most jellyfish species can live between three and six months but in this period they can reproduce with great success.
