John Edward Gray was a British zoologist. He was the elder brother of zoologist George Robert Gray and son of the pharmacologist and botanist Samuel Frederick Gray (1766–1828). The standard author abbreviation J.E.Gray is used to indicate this person as the author when citing a botanical name. The same is used for a zoological name.
Littorinimorpha is a large order of snails, gastropods, consisting primarily of sea snails, but also including some freshwater snails and land snails.
The Ophidiasteridae are a family of sea stars with about 30 genera. Occurring both in the Indo-Pacific and Atlantic Oceans, ophidiasterids are greatest in diversity in the Indo-Pacific. Many of the genera in this family exhibit brilliant colors and patterns, which sometimes can be attributed to aposematism and crypsis to protect themselves from predators. Some ophidiasterids possess remarkable powers of regeneration, enabling them to either reproduce asexually or to survive serious damage made by predators or forces of nature. Some species belonging to Linckia, Ophidiaster and Phataria shed single arms that regenerate the disc and the remaining rays to form a complete individual. Some of these also reproduce asexually by parthenogenesis.
Olive snails, also known as olive shells and olives, scientific name Olividae, are a taxonomic family of medium to large predatory sea snails with smooth, shiny, elongated oval-shaped shells.
Calliostomatidae is a family of sea snails within the superfamily Trochoidea and the clade Vetigastropoda.
Plakobranchidae is a family of sea slugs, marine opisthobranch gastropod mollusks in the superfamily Plakobranchoidea. They superficially resemble nudibranchs but they are sacoglossans, members of the clade Sacoglossa within the Opisthobranchia.
The Nassariidae, Nassa mud snails (US), or dog whelks (UK) are a taxonomic family of small to medium-sized sea snails, marine gastropod mollusks in the clade Neogastropoda.
Trochoidea is a superfamily of small to very large vetigastropod sea snails with gills and an operculum. Species within this superfamily have nacre as the inner shell layer. The families within this superfamily include the Trochidae, the top snails. This superfamily is the largest vetigastropodan superfamily, containing more than 2,000 species.
Goniasteridae constitute the largest family of sea stars, included in the order Valvatida. They are mostly deep-dwelling species, but the family also include several colorful shallow tropical species.
Lottiidae is a family of sea snails, specifically true limpets, marine gastropod mollusks in the superfamily Lottioidea and the clade Patellogastropoda.
Vanikoroidea is a superfamily of sea snails, marine gastropod molluscs in the clade Littorinimorpha. The superfamily Eulimoidea is a synonym of Vanikoroidea.
Vanikoridae is a family of minute to medium-sized sea snails, marine gastropod molluscs in the superfamily Vanikoroidea.
Velutinidae is a family of small sea snails, marine gastropod molluscs in the clade Littorinimorpha.
Pediculariinae is a subfamily of small to large predatory or parasitic sea snails, marine gastropod molluscs in the family Ovulidae and the superfamily Cypraeoidea, the cowries and the cowry allies. As of 2009, it comprises 48 described species of which 20 are regarded as valid by most scientists.
Calliostomatinae is a subfamily of gastropods, belonging to the family Calliostomatidae.
Calliaster is a genus of starfish in the family Goniasteridae
Poraniidae is a family of starfishes in the order Valvatida.
Gomophia is a genus of sea stars.
The Ancillariidae is a taxonomic family of sea snails, marine gastropod molluscs in the superfamily Olivoidea. They are gastropods, which belong to the larger group of mollusks. This family is part of the superfamily Cypraeoidea, which includes cowries, a well-known group of sea snails.
Cerro de Garnica National Park is a national park in Michoacán state of central Mexico. It protects 19.36 km2 in the mountains of the Trans-Mexican Volcanic Belt.
