Cypraeidae - Macrocypraea Zebra - Panama-3
Cypraeidae, commonly named the cowries ( cowry or cowrie), is a taxonomic family of small to large sea snails. These are marine gastropod mollusks in the superfamily Cypraeoidea, the cowries and cowry allies. Shell description Cypraeidae have adult shells which are very rounded, almost like an egg; they do not look like a typical gastropod shell. Their glossy, polished, ovate-shaped shells have beautiful patterns in a variety of colors. These patterns, combined with minor variations in shell form, have led some conchologists to recognize 60 genera and hundreds of species and subspecies. In virtually all of the species in the family Cypraeidae, the shells are extremely smooth and shiny. This is because in the living animal, the shell is nearly always fully covered with the mantle. The upper surface is typically convex, while the ventral side is flattened. Typically, no spire is visible in the fully adult shell. There is a long, narrow, aperture that runs along the length of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spire (mollusc)
A spire is a part of the coiled shell of molluscs. The spire consists of all of the whorls except for the body whorl. Each spire whorl represents a rotation of 360°. A spire is part of the shell of a snail, a gastropod mollusc, a gastropod shell, and also the whorls of the shell in ammonites, which are fossil shelled cephalopods. In textbook illustrations of gastropod shells, the tradition (with a few exceptions) is to show most shells with the spire uppermost on the page. The spire, when it is not damaged or eroded, includes the protoconch (also called the nuclear whorls or the larval shell), and most of the subsequent teleoconch whorls (also called the postnuclear whorls), which gradually increase in area as they are formed. Thus the spire in most gastropods is pointed, the tip being known as the " apex". The word "spire" is used, in an analogy to a church spire or rock spire, a high, thin, pinnacle. The "spire angle" is the angle, as seen from the apex, at which a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sponge
Sponges or sea sponges are primarily marine invertebrates of the animal phylum Porifera (; meaning 'pore bearer'), a basal clade and a sister taxon of the diploblasts. They are sessile filter feeders that are bound to the seabed, and are one of the most ancient members of macrobenthos, with many historical species being important reef-building organisms. Sponges are multicellular organisms consisting of jelly-like mesohyl sandwiched between two thin layers of cells, and usually have tube-like bodies full of pores and channels that allow water to circulate through them. They have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process. They do not have complex nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes, usually via flagella movements of the so-called " collar ...

Octopus
An octopus (: octopuses or octopodes) is a soft-bodied, eight-limbed mollusc of the order Octopoda (, ). The order consists of some 300 species and is grouped within the class Cephalopoda with squids, cuttlefish, and nautiloids. Like other cephalopods, an octopus is bilaterally symmetric with two eyes and a beaked mouth at the centre point of the eight limbs. An octopus can radically deform its shape, enabling it to squeeze through small gaps. They trail their appendages behind them as they swim. The siphon is used for respiration and locomotion (by water jet propulsion). Octopuses have a complex nervous system and excellent sight, and are among the most intelligent and behaviourally diverse invertebrates. Octopuses inhabit various ocean habitats, including coral reefs, pelagic waters, and the seabed; some live in the intertidal zone and others at abyssal depths. Most species grow quickly, mature early, and are short-lived. In most species, the male uses a speciall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Venom
Venom or zootoxin is a type of toxin produced by an animal that is actively delivered through a wound by means of a bite, sting, or similar action. The toxin is delivered through a specially evolved ''venom apparatus'', such as fangs or a stinger, in a process called ''envenomation''. Venom is often distinguished from ''poison'', which is a toxin that is passively delivered by being ingested, inhaled, or absorbed through the skin, and ''toxungen'', which is actively transferred to the external surface of another animal via a physical delivery mechanism. Venom has evolved in terrestrial and marine environments and in a wide variety of animals: both predators and prey, and both vertebrates and invertebrates. Venoms kill through the action of at least four major classes of toxin, namely necrosis, necrotoxins and cytotoxins, which kill cells; neurotoxins, which affect nervous systems; myotoxins, which damage muscles; and Hemotoxin, haemotoxins, which disrupt Thrombus, blood clotti ...

Conus Textile
''Conus textile'', the textile cone or the cloth of gold cone is a venomous species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails, cone shells or cones. Textile cone snails live mostly in the Indian Ocean, along the eastern coast of Africa and around Australia. Like all species within the genus ''Conus'', these snails are predatory and venomous. They are capable of stinging humans, therefore live ones should be handled carefully or not at all. Based on a report in 2004, about 30 human deaths have been attributed to cone snails.

Dorsum (anatomy)
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, '' Termi ...

Crabs
Crabs are decapod crustaceans of the infraorder Brachyura (meaning "short tailed" in Greek), which typically have a very short projecting tail-like abdomen, usually hidden entirely under the thorax. Their exoskeleton is often thickened and hard. They generally have five pairs of legs, and they have "pincers" or "claws" on the ends of the frontmost pair, scientifically termed the '' chelae''. They are present in all the world's oceans, in freshwater, and on land, often hiding themselves in small crevices or burrowing into sediment. Crabs are omnivores, feeding on a variety of food, including a significant proportion of algae, as well as detritus and other invertebrates. Crabs are widely consumed by humans as food, with over 1.5 million tonnes caught annually. True crabs first appeared in the fossil record during the Jurassic period, around 200 million years ago, achieving great diversity by the Cretaceous period; around 7,000 extant species in 96 families are known.

Cypraea Tigris
''Cypraea tigris'', commonly known as the tiger cowrie, is a species of cowry, a large sea snail, a marine gastropod mollusk in the family Cypraeidae, the cowries. Taxonomy The tiger cowry was one of the many species originally described by Carl Linnaeus in his 1758 10th edition of ''Systema Naturae'', and the species still bears its original name of ''Cypraea tigris''. Its specific epithet ''tigris'' relates to its common name "tiger" (the shell however is spotted, not striped). This species is the type species of the genus '' Cypraea''. Subspecies and forms * ''Cypraea tigris'' form ''incana'' Sulliotti, G.R., 1924 * ''Cypraea tigris'' form ''lyncicrosa'' Steadman, W.R. & B.C. Cotton, 1943 * ''Cypraea tigris'' var. ''schilderiana '' Cate, C.N., 1961 The variety ''Cypraea tigris'' var. ''schilderiana'' was recognized by Cate in 1961. It differs from ''Cypraea tigris'' in its large size (10–13 cm) and the lack of a thick marginal callus. This variety is found in t ...
