Toxopneustes
''Toxopneustes'' is a genus of sea urchins from the tropical Indo-Pacific. It contains four species. They are known to possess medically significant venom to humans on their pedicellariae (tiny claw-like structures). They are sometimes collectively known as flower urchins, after the most widespread and most commonly encountered species in the genus, the flower urchin (''Toxopneustes pileolus''). Species Species included in the genus are the following: Gallery File:Toxopneustes pileolus Okinawa 5m.JPG, ''Toxopneustes pileolus'' from Okinawa, Japan File:Toxopneustes pileolus.jpg, ''Toxopneustes pileolus'' from Réunion File:Toxopneustes roseus.jpg, '' Toxopneustes roseus'' from the Gulf of California, Mexico Mexico (Spanish: México), officially the United Mexican States, is a country in the southern portion of North America.

Toxopneustes Pileolus
''Toxopneustes pileolus'', commonly known as the flower urchin, is a widespread and commonly encountered species of sea urchin from the Indo-West Pacific. It is considered highly dangerous, as it is capable of delivering extremely painful and medically significant stings when touched. It inhabits coral reefs, seagrass beds, and rocky or sandy environments at depths of up to . It feeds on algae, bryozoans, and organic detritus. Its common name is derived from its numerous and distinctively flower-like pedicellariae, which are usually pinkish-white to yellowish-white in color with a central purple dot. It possesses short and blunt spines, though these are commonly hidden beneath the pedicellariae. The rigid "shell" (Sea urchin#Organs and test, test) is a variegated deep red and gray in color, though in rare cases it may be greenish to light purple. Taxonomy ''Toxopneustes pileolus'' is one of four species belonging to the genus ''Toxopneustes''. It belongs to the family (biology) ...

Toxopneustes Roseus
''Toxopneustes roseus'' is a species of sea urchin from the East Pacific. It is sometimes known as the rose flower urchin or the pink flower urchin. Like the related flower urchin, they are venomous. Taxonomy ''Toxopneustes roseus'' is one of the four species in the genus ''Toxopneustes''. It was first described by the American zoologist Alexander Emanuel Agassiz in 1863 as ''Boletia roseus''. The generic name ''Toxopneustes'' literally means "poison breath", derived from Greek τοξικόν άρμακον(''toksikón hármakon', "arrow oison) and πνευστος (''pneustos'', "breath"). The specific name ''roseus'' means "rosy" in Latin. Though it does not have a widely used common name, it is sometimes known as the "rose flower urchin" or the "pink flower urchin". More commonly, it is simply called a "flower urchin", though that name strictly applies only to the related Indo-West Pacific species, ''Toxopneustes pileolus''.

Toxopneustes Maculatus
''Toxopneustes maculatus'' is a rare species of sea urchin found in the Indo-West Pacific. Taxonomy ''Toxopneustes maculatus'' is one of the four species in the genus ''Toxopneustes''. It belongs to the family Toxopneustidae in the order Camarodonta. It was originally described as ''Echinus maculatus'' by the French naturalist Jean-Baptiste Lamarck in 1816, in the second book of his ''Histoire naturelle des animaux sans vertèbres'' series. The generic name ''Toxopneustes'' literally means "poison breath", derived from Greek τοξικόν άρμακον(''toksikón hármakon', "arrow oison) and πνευστος (''pneustos'', "breath"). The specific name ''maculatus'' means "spotted" in Latin. Description The appearance of living specimens is unknown, but like other flower urchins, it probably has prominent pedicellariae. It is only known from empty "shells" (tests). The tests have a distinctive color pattern with a large bright purple blotch around the entirety of the b ...

Toxopneustes Elegans
''Toxopneustes elegans'' is a species of sea urchin endemic to Japan. Like the closely related flower urchin, they are venomous. Taxonomy ''Toxopneustes elegans'' is one of the four species in the genus ''Toxopneustes''. It was first described by the German zoologist Ludwig Heinrich Philipp Döderlein in 1885. The generic name ''Toxopneustes'' literally means "poison breath", derived from Greek τοξικόν άρμακον(''toksikón hármakon', "arrow oison) and πνευστος (''pneustos'', "breath"). The specific name ''elegans'' means "elegant" in Latin. It has no English common name, but it is known as ''kurosuji-rappa-uni'' (クロスジラッパウニ) in Japanese (literally "black streaked flower urchin"). Description ''Toxopneustes elegans'' resemble the more common flower urchins, but they are smaller, reaching a maximum diameter of only . They also have smaller pedicellariae, though they are still characteristically flower-like in appearance. The most distinc ...

Pedicellaria
A pedicellaria (plural: pedicellariae) is a small wrench- or claw-shaped appendage with movable jaws, called valves, commonly found on echinoderms (phylum Echinodermata), particularly in sea stars (class Asteroidea) and sea urchins (class Echinoidea). Each pedicellaria is an effector organ with its own set of muscles, neuropils, and sensory receptors and is therefore capable of reflex responses to the environment. Pedicellariae are poorly understood but in some taxa, they are thought to keep the body surface clear of algae, encrusting organisms, and other debris in conjunction with the ciliated epidermis present in all echinoderms. In sea stars Types There are two major types of pedicellaria in sea stars: straight and crossed. Straight pedicellaria are typically larger and located on the body surface, whereas crossed pedicellaria are smaller and found more commonly on stalks, raised above the body surface or in clumps circling the spines. The crossed type is connected to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toxopneustidae
Toxopneustidae is a family of globular sea urchins in the class Echinoidea. Characteristics All Camarodonts have imperforate tubercles and compound ambulacral plates. In addition, the Toxopneustids are characterised by the peristome, or opening through the test, having a sharp margin with the buccal notches being prominent. The tubercles lack the crenulations or ring of cog-like structures that articulate with the spines in certain other families. The Aristotle's lantern, or jaw apparatus, has the keeled teeth and the epiphyses united above the foramen magnum, the V-shaped gap between the hemipyramids that support the lantern's tooth.

Sea Urchin
Sea urchins () are spiny, globular echinoderms in the class Echinoidea. About 950 species of sea urchin live on the seabed of every ocean and inhabit every depth zone from the intertidal seashore down to . The spherical, hard shells (tests) of sea urchins are round and spiny, ranging in diameter from . Sea urchins move slowly, crawling with tube feet, and also propel themselves with their spines. Although algae are the primary diet, sea urchins also eat slow-moving (sessile) animals. Predators that eat sea urchins include a wide variety of fish, starfish, crabs, marine mammals. Sea urchins are also used as food especially in Japan. Adult sea urchins have fivefold symmetry, but their pluteus larvae feature bilateral (mirror) symmetry, indicating that the sea urchin belongs to the Bilateria group of animal phyla, which also comprises the chordates and the arthropods, the annelids and the molluscs, and are found in every ocean and in every climate, from the tropics to the pol ...

East Pacific
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .
