Bostryx turritus is a species of tropical air-breathing land snail, a pulmonate gastropod mollusk in the family Bulimulidae.

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 sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. While these definitions may seem adequate, when looked at more closely they represent problematic species concepts. For example, the boundaries between closely related species become unclear with hybridisation, in a species complex of hundreds of similar microspecies, and in a ring species. Also, among organisms that reproduce only asexually, the concept of a reproductive species breaks down, and each clone is potentially a microspecies.

Land snail

A land snail is any of the numerous species of snail that live on land, as opposed to sea snails and freshwater snails. Land snail is the common name for terrestrial gastropod mollusks that have shells. However, it is not always easy to say which species are terrestrial, because some are more or less amphibious between land and fresh water, and others are relatively amphibious between land and salt water.

Bulimulidae family of molluscs

Bulimulidae is a taxonomic family of medium-sized to large, air-breathing, tropical and sub-tropical land snails, terrestrial pulmonate gastropod molluscs in the superfamily Orthalicoidea.

Distribution

This species was known from Trujillo Province in La Libertad Region (Pilsbry, 1896) [3] and Pariacoto in Ancash Region (Haas, 1955). [2] [4] Recently, Ramírez (2004) [5] reported it from Cerro Pasamayo and Salinas de Huacho in Lima Region. [2] She also refers to unpublished data by Weyrauch, who collected the species at Cerro Campana, 14 km north of Trujillo 07°58’54’S 079°06’24’W (selected as type locality by Ramírez) and near Chilete in Cajamarca Region. [2] Breure (1978) [6] reported the species from the same department near Magdalena. [2] Breure (2010) [2] reported it from Catzcal 1050 m, 09°54’43’S 077°49’40’W, Ancash Region, Peru. [2]

Trujillo Province is one of twelve provinces in the region La Libertad in Peru.

Henry Augustus Pilsbry U.S. zoologist

Henry Augustus Pilsbry was an American biologist, malacologist and carcinologist, among other areas of study. He was a dominant presence in many fields of invertebrate taxonomy for the better part of a century. For much of his career, his authority with respect to the classification of certain substantial groups of organisms was unchallenged: barnacles, chitons, North American terrestrial mollusks, and others.

Trujillo, Peru Place in La Libertad, Peru

Trujillo is a city in coastal northwestern Peru and the capital of La Libertad Region. It is the third most populous city and center of the third most populous metropolitan area of Peru. It is located on the banks of the Moche River, near its mouth at the Pacific Ocean, in the Moche Valley. This was a site of the great prehistoric Moche and Chimu cultures before the Inca conquest and subsequent expansion.

Zilch (1953) [7] reports Bostryx turritus turritus (shell height/shell width = 3.25) from Hacienda El Casa Grande (probably near 07°40’S 078°40’W) in La Libertad Region, and described Bostryx turritus tamboensis (shell height/shell width = 2.87) from the same locality, albeit from different elevations (1500 m resp. 1000 m). [2] According to Haas (1955) [4] – reporting a locality at 1360 m – his shells ‘are slightly more slender than the typical form’. [2] The specimens from Catzcal show a variation in ration shell height/shell width from 2.84 to 3.18 (mean 3.00; n = 7). [2] It is possible that this variation can also be found in the populations at the localities in La Libertad, in which case Bostryx turritus tamboensis should be considered a synonym of the nominate taxon. [2]

Description

Living animal are whitish-grey throughout, the black eye-retractors are shining through the tentacles and the dorsal side of the body. [2]
