Ancillariidae in the World Register of Marine Species
The Ancillariidae is a taxonomic family of sea snails, marine gastropod molluscs in the superfamily Olivoidea.[1][2] 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.
Distribution and habitat
Ancillariidae species can be found in tropical and subtropical waters around the world, particularly in the Indo-Pacific region. They inhabit diverse marine environments, including coral reefs, sandy bottoms, and seagrass beds.[3]
Physical characteristics
Ancillariidae shells are elongated, cylindrical, and slightly curved. They have a smooth and glossy surface, with some species displaying prominent ridges or knobs. The shells exhibit a wide range of colors and patterns, from plain white or cream to vibrant and intricate designs.[4][5]
Behavior and feeding habits
Ancillariidae snails are primarily nocturnal, being active at night to feed on algae, detritus, and small invertebrates. They use their specialized radula to scrape food particles from the substrate or graze on algae. During the day, they seek shelter in crevices or burrow in the sand to avoid predators and excessive sunlight.[6]
Reproduction
Reproduction in Ancillariidae involves separate sexes, with individuals being either male or female.[7] They release eggs and sperm into the water, where fertilization takes place externally. The larvae develop into planktonic forms, drifting in ocean currents until they settle on the substrate and undergo metamorphosis into adults.
