Sinustrombus sinuatus, common name the laciniate conch, [1] is a species of sea snail, a marine gastropod mollusc in the true conch family, Strombidae. [2] It is native to the tropical Indo-Pacific region.

Description

The shell of S. sinuatus is thick and solid with a large body whorl. [3] The maximum length is 13 cm (5 in), but a more common size is 10 cm (4 in). [1] The short spire consists of about twelve whorls; the exterior of the shell is white, blotched or spotted with yellow, orange or light tan, and the interior is brown, purple or pink. [4] It is rather varied in morphology, with the lip of the aperture having a number of blunt finger-like processes, which vary from being almost unnoticeable to being prominent. The difference in shape of these variations is larger than the difference between the shape of this mollusc and the related species Lambis millepeda , Lambis scorpius and Lambis lambis , which it resembles. [3]

Distribution and habitat

Sinustrombus sinuatus is found in tropical and sub-tropical waters in southeastern Asia and Oceania. Its range extends from Sri Lanka and the eastern coast of India to the Philippines, Japan, Taiwan, Indonesia, Melanesia, Papua New Guinea and northern Australia. [1] Its typical habitat is a sandy substrate with algae and coral fragments in areas with low turbidity. It occurs from the low intertidal zone down to about 20 m (66 ft). [3]

Ecology

In the nineteenth century there was a widespread belief that members of the family Strombidiae were carnivorous but this proved to be false. S. sinuatus inhabits soft substrates where it feeds on fragments of algae, ingesting sand and detritus, and deriving its nutrition from the decomposing organic material. [5] It is an active mollusc, able to use its slender foot and robust operculum to flip itself off the seabed, in locomotion or defence. [6] Its operculum and the finger-like processes on the lip of the shell are also used in the behaviour involved in shell-righting. [7]

Strombidae, commonly known as the true conchs, is a taxonomic family of medium-sized to very large sea snails in the superfamily Stromboidea, and the Epifamily Neostromboidae. The term true conchs, being a common name, does not have an exact meaning. It may generally refer to any of the Strombidae but sometimes is used more specifically to include only Strombus and Lambis. The family currently includes 26 extant, and 10 extinct genera.

<i>Aliger gigas</i> Species of mollusc

Aliger gigas, originally known as Strombus gigas or more recently as Lobatus gigas, commonly known as the queen conch, is a species of large sea snail, a marine gastropod mollusc in the family of true conches, the Strombidae. This species is one of the largest molluscs native to the Caribbean Sea, and tropical northwestern Atlantic, from Bermuda to Brazil, reaching up to 35.2 centimetres (13.9 in) in shell length. A. gigas is closely related to the goliath conch, Lobatus goliath, a species endemic to Brazil, as well as the rooster conch, Aliger gallus.

<i>Strombus</i> Genus of gastropods

Strombus is a genus of medium to large sea snails, marine gastropod molluscs in the family Strombidae, which comprises the true conchs and their immediate relatives. The genus Strombus was named by Swedish Naturalist Carl Linnaeus in 1758. Around 50 living species were recognized, which vary in size from fairly small to very large. Six species live in the greater Caribbean region, including the queen conch, Strombus gigas, and the West Indian fighting conch, Strombus pugilis. However, since 2006, many species have been assigned to discrete genera. These new genera are, however, not yet found in most textbooks and collector's guides.

The operculum is a corneous or calcareous anatomical structure like a trapdoor that exists in many groups of sea snails and freshwater snails, and also in a few groups of land snails; the structure is found in some marine and freshwater gastropods, and in a minority of terrestrial gastropods, including the families Helicinidae, Cyclophoridae, Aciculidae, Maizaniidae, Pomatiidae, etc.

Laevistrombus canarium is a species of edible sea snail, a marine gastropod mollusc in the family Strombidae. Known from illustrations in books dating from the late 17th century, L. canarium is an Indo-Pacific species occurring from India and Sri Lanka to Melanesia, Australia and southern Japan. The shell of adult individuals is coloured from light yellowish-brown to golden to grey. It has a characteristic inflated body whorl, a flared, thick outer lip, and a shallow stromboid notch. The shell is valued as an ornament, and because it is heavy and compact, it is also often used as a sinker for fishing nets.

Titanostrombus goliath, previously known as Lobatus goliath and Strombus goliath, common name the goliath conch, is a species of very large edible sea snail, a marine gastropod mollusk in the family Strombidae, the true conchs. T. goliath is one of the largest mollusks of the Western Atlantic Ocean, and also one of the largest species among the Strombidae. It was once considered endemic to Brazil, but specimens have also been recently found in the waters of Barbados. Brazilian common names for this species include búzio de chapéu or búzio, and búzio de aba or buzo in. Some phylogenetic hypotheses consider T. goliath as closely related to the queen conch, Aliger gigas.
