Max Size: 2.5 cm (1 in)
Habitat: Estuaries and rocky substrates, particularly around oyster reefs
Diet: Bivalves
Fun Facts:
- Named due to their mechanism of feeding: they use a tongue-like structure (radula) to rasp away at the shells of bivalves such as oysters and mussels, “drilling” a small pinhole through which to feed on the soft tissue underneath
- Distinct from mud dogs due to their beige-orange flesh, and lighter, more rigid shell
- Can devastate oyster reefs
