Bornellidae
Bornellidae is a family of small, predatory sea snails, marine gastropod molluscs in the superfamily Conoidea. The family was previously placed in the family Conidae and more recently in the family Conilidae, but it has been shown to be distinct from either group and is currently recognised as a separate family in the superfamily Conoidea. The family has a worldwide distribution, but it is most diverse in the tropical Indo-Pacific region.
Common Names
Bornellidae are commonly referred to as "cone snails" or "cone shells".
Characteristics
Members of the Bornellidae are characterised by their small size, often less than 20 mm in length. Their shells are typically conical and smooth, with a pointed apex and a wide, open aperture. The shells are often brightly coloured and patterned, with a variety of colours and designs. The body of the snail is soft and fleshy, with a long, retractable proboscis that contains a venomous harpoon. Bornellidae are carnivorous and feed on other marine invertebrates, such as worms, molluscs, and other snails.
Environment
Bornellidae are found in a variety of marine habitats, including coral reefs, rocky shores, and sandy bottoms. They are typically found in shallow water, but some species can be found at depths of up to 100 meters. Bornellidae are active predators and are often found hiding in crevices or under rocks during the day. They are most active at night, when they emerge to hunt for prey.
