| In particular, they noted that modem patelloid limpets have segmented scars due to bundling of the large retractor muscle. |

| Cayenne keyhole limpets are easily identified due to the keyhole-shaped orifice at the apex of the shell. |
| Unlike other limpets, most keyhole limpets have a small hole in the top of their shell. |
| Modern species thrive under intense herbivory from snails, chitons, and limpets, and this has been suggested as one reason for their success. |
| Brains of limpets and abalones are much simpler than brains of garden snails and slugs in histological differentiation. |
