The shell[change | change source]
The Knobbed Whelk has a spiral shell with knobs (or spines) along its shoulder. The shell is up to 9.5 inches (24 cm) long. The shell is light gray to tan, and often has brown and white streaks.
Diet[change | change source]
Knobbed Whelks eat clams. They open the clam with their hard shell, and insert their long proboscis. They eat using a radula, a rough tongue-like organ that has thousands of tiny denticles (tooth-like protrusions).
