Chiropsoides Buitendijki
''Chiropsoides'' is a genus of box jellyfish in the family Chiropsalmidae. It is monotypic, with a single species, ''Chiropsoides buitendijki''. The most distinct species characteristics are the shape of the gastric saccules, the pedalial canals, and the unilateral pedalial branching. Anatomy and morphology As members of the phylum Cnidaria'', C. buitendijki'' have flexible, tubule-shaped stinging cells called nematocysts that coil within a capsule structure and can be launched outward to deliver a sting to prey. Many jellyfish of the class Cubozoa have tubules that can be categorized as microbasic, meaning that the tubule is not longer than the capsule and thus does not need to coil up to fit inside. More specifically, ''C. buitendijki'' have tubules called mastigophores, meaning "whip-bearing". Most Cubozoans, including ''C. buitendijki,'' have p-mastigophores, meaning that the shaft and tubule differ noticeably in girth. This structure is believed to carry most of the venom ...

Chirodropida
Chirodropida is an order of box jellyfishes. They can be distinguished from other box jellyfish by the presence of branched muscular bases at the corners of their cubic umbrella, and of small saccules associated with the gastric cavity. They typically have multiple tentacles at each corner. References * * Chirodropida, Cubozoa Taxa named by Ernst Haeckel {{Cubozoa-stub ...

Box Jellyfish
Box jellyfish (class Cubozoa) are cnidarian invertebrates distinguished by their box-like (i.e. cube-shaped) body. Some species of box jellyfish produce potent venom delivered by contact with their tentacles. Stings from some species, including ''Chironex fleckeri'', '' Carukia barnesi'', ''Malo kingi'', and a few others, are extremely painful and often fatal to humans. Taxonomy and systematics At least 51 species of box jellyfish were known as of 2018. These are grouped into two orders and eight families. A few new species have since been described, and it is likely that additional undescribed species remain. Cubozoa represents the smallest cnidarian class with approximately 50 species.

Chiropsalmus Quadrumanus
} ''Chiropsalmus quadrumanus'', commonly known as the four-handed box jellyfish, is a species of box jellyfish found in the western Atlantic Ocean, the Gulf of Mexico and the Pacific Ocean. The sting is venomous and dangerous to humans, especially children. Taxonomy Little and/or poor taxonomic research has been conducted on ''Chiropsalmus quadrumanus''. In 2006, Lisa-ann Gershwin noted that the South American neotype's cnidome was differing from the United States species. Several studies on the species have been conducted since then. One in 1975 gives statistics and charts that clearly shows the differing cnidomes of U.S. species compared to that of the neotype of Gershwin's. No new taxa have been erected to accommodate the research.

The body is composed of a gelatinous material and the top edges are rounded while the top surf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chiropsalmus Quadrigatus
''Chironex yamaguchii'', commonly known as ハブクラゲ (transliterated as habu-kurage, literally meaning "Viper Jellyfish" in Japanese) and as "hub jellyfish" due to erroneous machine translations, is a species of box jellyfish found in coastal waters around Japan, on Okinawa and the Ryukyu Islands, and in the Philippines. Discovered in 2009, it is highly venomous and has been the cause of several deaths in Japanese waters. Taxonomy In the past, this species was considered conspecific with ''Chiropsalmus quadrigatus'' found in Malaysia. That name however, is now considered as a '' nomen dubium'' and it is no longer recognized as a separate species. It has now been established that ''Chironex yamaguchii'' is a different species and is more closely related to ''Chironex fleckeri'', however, the name ''Chiropsalmus quadrigatus'' is widely used in the literature.

Jellyfish
Jellyfish and sea jellies are the informal common names given to the medusa-phase of certain gelatinous members of the subphylum Medusozoa, a major part of the phylum Cnidaria. Jellyfish are mainly free-swimming marine animals with umbrella-shaped bells and trailing tentacles, although a few are anchored to the seabed by stalks rather than being mobile. The bell can pulsate to provide propulsion for highly efficient locomotion. The tentacles are armed with stinging cells and may be used to capture prey and defend against predators. Jellyfish have a complex life cycle; the medusa is normally the sexual phase, which produces planula larvae that disperse widely and enter a sedentary polyp phase before reaching sexual maturity. Jellyfish are found all over the world, from surface waters to the deep sea. Scyphozoans (the "true jellyfish") are exclusively marine, but some hydrozoans with a similar appearance live in freshwater. Large, often colorful, jellyfish are common in ...

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 mainly like muscular hydrostats. Most forms of tentacles are used for grasping and feeding. Many are sensory organs, variously receptive to touch, vision, or to the smell or taste of particular foods or threats. Examples of such tentacles are the eyestalks of various kinds of snails. Some kinds of tentacles have both sensory and manipulatory functions. A tentacle is similar to a cirrus, but a cirrus is an organ that usually lacks the tentacle's strength, size, flexibility, or sensitivity. A nautilus has cirri, but a squid has tentacles. Invertebrates Molluscs Many molluscs have tentacles of one form or another. The most familiar are those of the pulmonate land snails, which usually have two sets of tentacles on the head: when exte ...
