| − | The '''whelk''' or '''buckie''' is a large marine [[gastropod]] ([[snail]]) found in temperate waters. Whelks are sometimes confused with [[conch|conches]]. While both are gastropods, they differ in [[shell]] morphology, with whelks having smaller more slender shells while conch typically have a broader shell with more exaggerated knobs. Also, conches tend to be more [[tropical]] [[vegetarians]], while whelks are [[carnivorous]] and [[temperate]]. | + | The '''whelk''' or '''buckie''' is a large marine [[gastropod]] ([[snail]]) found in temperate waters.

| − | Whelks are [[scavengers]] and [[carnivores]], equipped with an extensible [[proboscis]] that is tipped with a file-like [[radula]]. The radula is used to bore holes through the shells of [[clam]]s, [[crabs]] and [[lobster|lobsters]]. They also have a large, muscular foot with which they hold their victims. Like other [[mollusk]]s, whelks have a [[mantle (mollusc)|mantle]], a thin layer of tissue located between the body and the shell that creates the shell. Whelks build their hard shells from the [[calcium carbonate]] they extract from the seas. The shells can grow up to 9.5 inches (24 cm) long. | + | Whelks are [[scavengers]] and [[carnivores]], equipped with an extensible [[proboscis]] that is tipped with a file-like [[radula]].

| | Whelk shells are generally light grey to tan, often having brown and white streaks. The shells coil dextrally (right-handed, or in a clockwise direction) and have a long siphonal canal. The shell shape of individual specimens may vary widely in both coloration and sculpture. | | Whelk shells are generally light grey to tan, often having brown and white streaks.

| − | Whelk [[egg|eggs]], when they dry on the beach, become brittle, resembling a necklace stringed with medallion-shaped egg pouches. These are sometimes referred to as a "mermaid's necklace". They are abundant in Virginia Beach, [[Virginia]]. | + | Whelk [[egg]]s, when they dry on the beach, become brittle, resembling a necklace stringed with medallion-shaped egg pouches.

| − | The [[knobbed whelk]], ''Busycon carica'', is the second-largest species, ranging up to 12 in. (40.6 cm). They have [[tubercle]]s (or spines) along the shoulder. Knobbed whelks eat clams. They open the clam with their hard shell and insert their long proboscis. Today the knobbed whelk is a common predator of the [[Foreshore|intertidal]] mudflats and can be found offshore to 26 fathoms (48 m). The [[channeled whelk]] is slightly smaller than the knobbed whelk and has a smooth shell with channels following the swirls at the top of the shell. | + | The [[knobbed whelk]], ''Busycon carica'', is the second-largest species, ranging up to 12 in.
