Carybdea Rastoni
''Carybdea'' is a genus of venomous box jellyfish within the family Carybdeidae that currently consists of a total of 8 species. This genus of jellyfish are often found in warm waters around the world in waters such as the Mediterranean Sea, the Pacific Ocean, and off the coast of Africa. Their sting can cause a range of effects depending on the species. These invertebrates will go through both sexual and asexual reproduction as they transform from a polyp to medusa. Carybdea have a box-shaped bell with four tentacles and eye-like sensory structures. There are distinct physical markings that differentiate many species within the genus. While Carybdea use their venom to act as predators, they are also preyed on by turtles and various fish. They feed on plankton, invertebrates, fish, and some crustaceans. Classification Class This genus of venomous box jellyfish is categorized in the class Cubozoa. Cubozoans are referred to as box jellyfish due to the fact that when viewing th ...

Carybdea Marsupialis
''Carybdea marsupialis'' or Mediterranean Box Jelly is a venomous species of box jellyfish, in the small family Carybdeidae within the class Cubozoa. Description ''Carybdea marsupialis'' is a small transparent jellyfish with a box-shaped bell about across, at the four lower corners of which are four elongated tentacles up to long. The bell has a number of small white or yellowish warts with stinging cells, and near the margin, equidistant from the tentacles, are four rhopalia (sensory structures with ocelli). This species can be distinguished from other similar species by the red banding on the tentacles. Distribution ''Carybdea marsupialis'' was once considered a widespread species found in warm oceans around the world. Taxonomic reviews have shown that most of these are other species in the genus '' Carybdea'', with the true ''C. marsupialis'' essentially restricted to the Mediterranean Sea. It is the only box jellyfish in this sea. It is pelagic and is present in the upp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesentery (zoology)
In zoology, a mesentery is a membrane inside the body cavity of an animal. The term identifies different structures in different phylum, phyla: in vertebrates it is a double fold of the peritoneum enclosing the intestines; in other organisms it forms complete or incomplete partitions of the body cavity, whether that is the coelom or, as in the Anthozoa, the gastrovascular cavity. The word "mesentery" is derived from the Greek ''mesos'', "in the middle" and ''enteron'', an "intestine". Vertebrates In vertebrates, a mesentery is a membrane consisting of a double fold of peritoneum that encloses the intestines and their associated organs and connect them with the dorsal wall of the abdominal cavity. In invertebrates, a mesentery is a support or partition in a body cavity serving a similar function to the mesenteries of vertebrates. Bilateria In Bilateria, bilaterally symmetrical organisms, there is often a major mesentery separating the two halves of the coelom. In segmented org ...

Mating
In biology, mating is the pairing of either opposite-sex or hermaphroditic organisms for the purposes of sexual reproduction. ''Fertilization'' is the fusion of two gametes. '' Copulation'' is the union of the sex organs of two sexually reproducing animals for insemination and subsequent internal fertilization. Mating may also lead to external fertilization, as seen in amphibians, fishes and plants. For most species, mating is between two individuals of opposite sexes. However, for some hermaphroditic species, copulation is not required because the parent organism is capable of self-fertilization (autogamy); for example, banana slugs. The term ''mating'' is also applied to related processes in bacteria, archaea and viruses. Mating in these cases involves the pairing of individuals, accompanied by the pairing of their homologous chromosomes and then exchange of genomic information leading to formation of recombinant progeny (see mating systems).

Copula Sivickisi
''Copula'' is a monotypic genus of box jellyfish in the family Tripedaliidae of the phylum Cnidaria. The only species in the genus is ''Copula sivickisi'', a very small gelatinous, bell-shaped jellyfish with four tentacles that is active only at night. It is unusual among box jellyfish in having a mating ritual and internal fertilization. Its scientific name honours the Lithuanian zoologist Pranciškus Baltrus Šivickis. Description ''Copula sivickisi'' is a very small species of jellyfish, the medusa growing to about in diameter. The bell is a more "boxy" shape than that of the umbrella-like true jellyfishes. The eight gonads can be seen inside the transparent bell. In males these are orange hemispherical structures near the apex of the bell, and in females they are white-speckled, leaf-like structures. There is a central manubrium, a transparent tubular structure hanging down from the centre of the underside of the bell and there are four slender tentacles hanging from the ...

Carybdea Xaymacana
''Carybdea xaymacana'' is a venomous species of cnidarian, in the small family Carybdeidae within the class Cubozoa. The species has been documented off the coast of Mexico and Australia. To distinguish this species from other cubozoans along the Mexican coasts, one can note its four pedalia, each containing a single tentacle In zoology, a tentacle is a flexible, mobile, and elongated organ present in some species of animals, most of them invertebrates. In animal anatomy, tentacles usually occur in one or more pairs. Anatomically, the tentacles of animals work main ..., and its heart-shaped rhopaliar niche ostium.
