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.
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]
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]
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 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.
Genera within the family Ancillariidae include: [8]
Conoidea is a superfamily of predatory sea snails, marine gastropod mollusks within the suborder Hypsogastropoda. This superfamily is a very large group of marine mollusks, estimated at 340 recent valid genera and subgenera, and considered by one authority to contain 4,000 named living species.
Olive snails, also known as olive shells and olives, scientific name Olividae, are a taxonomic family of medium to large predatory sea snails with smooth, shiny, elongated oval-shaped shells.
The Terebridae, commonly referred to as auger shells or auger snails, is a family of predatory marine gastropods in the superfamily Conoidea. They have extremely high-spired shells with numerous whorls; their common name refers to the resemblance of their shells to rock-drill bits. More than 400 species are recently known worldwide.
Amalda is a genus of medium-sized sea snails, a marine gastropod mollusc in the family Ancillariidae, the olives and allies.
Mitridae, known as mitres or mitre shells, are a taxonomic family of sea snails, widely distributed marine gastropod molluscs in the clade Mitroidea.
The Nassariidae, Nassa mud snails (US), or dog whelks (UK) are a taxonomic family of small to medium-sized snails, mostly marine gastropod mollusks in the clade Neogastropoda. These snails have rounded shells with a high spire, an oval aperture, and a siphonal notch. This family of snails is found worldwide.
Olivellinae, are a subfamily of small predatory sea snails with smooth, shiny, elongated oval-shaped shells, in the family Olividae. The shells sometimes show muted but attractive colors, and may have some patterning.
