Buccinids are carnivorous; some hunt their prey and others scavenge. They have a wide, mostly invertebrate diet including urchins, worms, crustaceans and bivalves, although some also eat small fishes. Buccinids have strong chemosensory abilities. As water passes through their siphon into their mantle cavity, it flows through the osphradium, the bucchinid version of a nose. They can smell their prey up to several meters away. Buccinids also have a formidable proboscis, which can protrude up two times as long their body length. At the end of the proboscis, they have a “radula” which can have one or two teeth modified as harpoons for piercing or cutting prey. In other types, the radular teeth are modified for drilling through calcarious shells of bivalves or barnacles. Typically they also apply shell-softening chelating chemicals secreted from a gland in the foot, to make a clean hole in the shell big enough to pass their proboscis and buccal (mouth) tube through to eat the soft tissues.
