The Red Queen Conch ( Strombus pugilis ) is a snail from the family of winged snails (genus Strombus ), which in the western Atlantic is widespread.
features
The elongated, solid snail shell of Strombus pugilis , which in adult snails reaches a length of about 13 cm, has a large body circumference and a small, pointed thread. The whorls are studded with knotty spines in the direction of the apex, whereby their size increases towards the last whorl. The notch for the siphonal canal and the stromboid notch for the second eye are clearly defined. The rear corner of the outer lip is stretched backwards. The color of the housing varies from yellow to light to dark orange. The inside of the case mouth is white, the front end is dark purple. The claw-shaped operculum is used for jerky locomotion like other fencing snails .
The Veliger larvae go through a long pelagic phase during which they feed on plankton .
Most similar to the red snail is the species Strombus alatus , living further north , whose shell has fewer protruding spines and a slightly more protruding outer lip. It is controversial whether there are two species or just two subspecies.
distribution and habitat
The red fenced snail occurs in the western Atlantic Ocean from Florida to Brazil , around Bermuda and in the Caribbean Sea .
The snail lives on sand. Like other wing snails, it feeds on algae .
Use and hazard
Strombus pugilis is mainly collected for its meat, and also for its shell, which is sold as jewelry.
