Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology.

Sea Slug
Sea slug is a common name for some marine invertebrates with varying levels of resemblance to terrestrial slugs. Most creatures known as sea slugs are gastropods, i.e. they are sea snails (marine gastropod mollusks) that over evolutionary time have either completely lost their shells, or have seemingly lost their shells due to having a greatly reduced or internal shell. The name "sea slug" is most often applied to nudibranchs, as well as to a paraphyletic set of other marine gastropods without obvious shells. Sea slugs have an enormous variation in body shape, color, and size. Most are partially translucent. The often bright colors of reef-dwelling species implies that these animals are under constant threat of predators, but the color can serve as a warning to other animals of the sea slug's toxic stinging cells ( nematocysts) or offensive taste. Like all gastropods, they have small, razor-sharp teeth, called radulas. Most sea slugs have a pair of rhinophores—sens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cnidosac
A cnidosac is an anatomical feature that is found in the group of sea slugs known as aeolid nudibranchs, a clade of marine opisthobranch gastropod molluscs. A cnidosac contains cnidocytes, stinging cells that are also known as cnidoblasts or nematocysts. These stinging cells are not made by the nudibranch, but by the species that it feeds upon. However, once the nudibranch is armed with these stinging cells, they are used in its own defense. Description and functions The sea slugs within the nudibranch clade Aeolidida have protruding cerata (singular "ceras") on their dorsal surface. At the tip of each ceras is a small sac in which nematocysts (stinging cells) are stored. These nematocysts originate in the cnidarians (such as sea anemones, hydroids, jellyfish, corals, siphonophores, etc.) that are the food source for aeolid nudibranchs. Example '' Glaucus atlanticus'' is a blue pelagic aeolid nudibranch. Individuals in this species can be dangerous for humans to handle; the cnid ...

Cerata
:''The tortrix moth genus ''Cerata'' is considered a junior synonym of ''Cydia. Cerata, singular ceras, are anatomical structures found externally in nudibranch sea slugs, especially in aeolid nudibranchs, marine opisthobranch gastropod mollusks in the clade Aeolidida. The word ceras comes from the Greek word "κέρας", meaning "horn", a reference to the shape of these structures. Cerata are dorsal and lateral outgrowths on the upper surfaces of the body of these nudibranchs. Function Cerata greatly extend the surface area of nudibranchs and aid in respiration, the process of gas exchange for metabolic use. Cerata are also used, in some cases, for attack and defense. In many aeolid nudibranchs, the digestive system extends into the cerata. These nudibranchs eat stinging celled animals (Cnidarians) such as anemones, hydroids and sea fans or Portuguese men o' war.

Diverticulum (mollusc)
As applied to mollusks, the New Latin term diverticulum is an anatomical feature. The term is most often encountered in the plural form as "diverticula", "hepatic diverticula", or "digestive diverticula", which are anatomical terms for organs which are visible from the outside of the body in a clade of sea slugs known as aeolid nudibranchs, marine opisthobranch gastropod molluscs. The term is also applied to mollusk anatomy in other contexts: land slugs such as ''Lehmannia marginata'' have a caecal diverticuluand there is also a diverticulum in the stomach of certain Bivalviabr> Description and functions In the Aeolidida Individual animals within the nudibranch clade Aeolidida have an array of long protruding structures called cerata on their dorsal surface. Located within the cerata of these nudibranchs are hepatic diverticula, which are an outgrowth of the digestive gland or hepatopancreas of the animal. The cerata are translucent, and thus the contents of the diverticula are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banyuls-sur-Mer
Banyuls-sur-Mer (; ) is a commune in the Pyrénées-Orientales department in southern France. It was first settled by Greeks starting in 400 BCE. Geography Location Banyuls-sur-Mer is located in the canton of La Côte Vermeille and in the arrondissement of Céret. Banyuls-sur-Mer is neighbored by Cerbère, Port-Vendres, Argelès-sur-Mer and Collioure on its French borders, and by Espolla, Rabós, Colera and Portbou on its Spanish borders. The foothills of Pyrenees, the ''Monts Albères'', run into the Mediterranean Sea in Banyuls-sur-Mer, creating a steep cliff line. Toponymy Banyuls-sur-Mer was first mentioned in 981 as ''Balneum'' or ''Balneola''. In 1074, the town started being called ''Bannils de Maritimo'' in order to distinguish it from Banyuls-dels-Aspres, which lies away. In 1197, the town was mentioned as ''Banullis de Maredine'' and in 1674. In Catalan, it has been called ''Banyuls de la Marenda'' since the 19th century. The name Banyuls indicates the ...

Cap Ghir
A cap is a flat headgear, usually with a visor. Caps have crowns that fit very close to the head. They made their first appearance as early as 3200 BC. Caps typically have a visor, or no brim at all. They are popular in casual and informal settings, and are seen in sports and fashion. They are typically designed for warmth, and often incorporate a visor to block sunlight from the eyes. They come in many shapes, sizes, and are of different brands. Baseball caps are one of the most common types of cap.

Mollusc
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.

Gastropod
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.
