Knobbed Whelk- Busycon carica


Lives in inlets, Sounds, and offshore shallow waters


From Cape Cod to Northern Florida


The mollusk’s shell is 5 to 9 inches and is characterized by the knobs on the whirl.

Ecological Notes

The whelk is a carnivore that feeds on mainly bivalves. It is a good indicator of the health of the environment it is in.

Personal Information I found this shell when we were doing our second collection on the beach. It was very intact for a whelk shell.
