Behavior
Busycon whelks are scavengers and carnivores, equipped with a proboscis tipped with a file-like radula used to bore holes through the shells of barnacles, clams, crabs, and lobsters. They have a large, muscular foot with which they hold their victims. Small sharks, gulls, crabs, and other gastropods are known to feed upon them.
The knobbed whelk, Busycon carica, is the second-largest species, growing up to 30 cm long. They have tubercles (spines) along the shoulder. They open clams with their muscular foot and insert their long proboscis to digest the flesh. The knobbed whelk is a common predator of the foreshore mudflats as far offshore as 50 m.

Famous quotes containing the word behavior:
“The confusion of emotions with behavior causes no end of unnecessary trouble to both adults and children. Behavior can be commanded; emotions can’t. An adult can put controls on a child’s behavior—at least part of the time—but how do you put controls on what a child feels? An adult can impose controls on his own behavior—if he’s grown up—but how does he order what he feels?”
—Leontine Young (20th century)
