![]() ![]() ![]() Malacologists and ecologists have recommended a reduction in its exploitation rate initiatives in Thailand are attempting to ensure the possibility of reproduction in young-adult individuals and manage the natural populations in general. The dog conch is an economically important species in the Indo-West Pacific, and several studies indicate that it may be suffering population declines due to overfishing and overexploitation. It is also a prey species for vertebrates including macaques, and also humans, who consume the soft parts in a wide variety of dishes. Predators of this snail include carnivorous gastropods such as cone snails and volutes. The maximum life span is 2.0 to 2.5 years. Larvae of this species spend several days as plankton, undergoing a series of transformations until they reach complete metamorphosis. It is gonochoristic and sexually dimorphic, depending on internal fertilization for spawning. ![]() canarium lives on muddy and sandy bottoms, grazing on algae and detritus. The former behaviour, however, involves movement sequences unique to this species. The dog conch exhibits behaviours common among the Strombidae, including burrowing and a characteristic leaping form of locomotion. A molecular analysis conducted in 2006 based on DNA sequences of histone and mitochondrial genes demonstrated that Laevistrombus canarium, Doxander vittatus, and Labiostrombus epidromis are closely related species. The animal has an elongated snout, thin eyestalks with well-developed eyes and sensory tentacles, and a narrow, strong foot with a sickle-shaped operculum. The external anatomy of the soft parts of this species is similar to that of other strombid snails. 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. It has a characteristic inflated body whorl, a flared, thick outer lip, and a shallow stromboid notch. The shell of adult individuals is coloured from light yellowish-brown to golden to grey. 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. Laevistrombus canarium ( commonly known as the dog conch or by its better-known synonym, Strombus canarium) is a species of edible sea snail, a marine gastropod mollusc in the family Strombidae (true conches). Strombus gibbus Issel & Canefri, 1876.Strombus canarium Linnaeus, 1758 ( original combination).The shaded area indicates the distribution of Laevistrombus canarium within the Western Central Pacific, according to Poutiers, 1998. ![]()
