Limpets & Keyhole Limpets
- Approximately 35 species of Limpets live in North American waters.
- Conical shells may be smooth or ribbed, round or narrow at the base, and may reach 4 inches in diameter.
- Limpets living in turbulent wave areas have lower shell heights than those in calmer conditions. Limpets living among grasses have longer, narrower shells.
- Keyhole limpets have a hole or slit near the apex of their conical shell that sets them apart from true limpets.
