Bornella
''Bornella'' is a genus of sea slugs, specifically dendronotid nudibranchs in the family Bornellidae. There has not been much research on this genus. Their biology is mostly unknown, except that they seem to feed exclusively on hydroids. Distribution These nudibranchs occur in the Indo-West Pacific. In addition there is one species in the tropical eastern Pacific, and one species in the western Atlantic. Description Their body is covered with cerata-like dorsal and lateral outgrowths, with finger-like branches. They have an attached cluster of gills. Their rounded head shows on each side of the mouth a tentacle, with tiny finger-like papillae. The sheath of the rhinophore stands high and resembles the dorsal processes. Feeds on hydroids. The various species differ in their color pattern and their number of dorsal and lateral outgrowths and the number of branches on their rhinophore sheath. Anatomy These nudibranchs are characterized by an unpaired oral gland. In their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bornella Anguilla
''Bornella anguilla'' is a species of sea slug, a nudibranch, a marine gastropod mollusk in the family Bornellidae. This species is widely distributed throughout the tropical waters of the Indo-West Pacific. This species In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate s ... can grow up to a length of 8 cm.

Bornellidae
''Bornellidae'' is a family of nudibranch sea slug - marine gastropod molluscs in the superfamily Tritonioidea. This family is within the clade Cladobranchia (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). Description Nudibranch species within the ''Bornellidae'' family have elongated bodies, with pairs of cerata-like dorsal and lateral appendages, with finger-like branches, running along the length of the body. Each of these appendages has an attached cluster of gills. Their rounded head has a tentacle on either side of the mouth, with tiny finger-like papillae. The rhinophores on the head resemble the dorsal appendages. Nudibranchs within this family are believed to feed exclusively on hydroids.

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 e ...

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.
