Diodora alta is a species of sea snail, a marine gastropod mollusk in the family Fissurellidae, the keyhole limpets and slit limpets. [1] [2]
The size of the shell varies between 7 mm and 14 mm. The high shell has a subconic shape. It is white, often more or less covered with broad ashy black rays, which may be seen through the shell. Its sculpture shows prominent radiating ribs, of which the alternate ones are excessively developed, and intermediate small raised lines. The shell has many concentric ridges, which are less prominent than the larger radiating ribs, and more so than the others. The summit is nearer to and somewhat inclined towards the anterior extremity. The small fissure has an ovate-elliptic shape. The margin is pectinated by the radiating ribs. [3]
This species occurs in the Pacific Ocean from the Gulf of California, Western Mexico to North Peru; off the Galápagos Islands.
Diodora cayenensis, the Cayenne keyhole limpet, is a species of small to medium-sized sea snail or limpet, a western Atlantic marine prosobranch gastropod mollusk in the family Fissurellidae, the keyhole limpets.

Lottia scabra or the rough limpet is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Lottiidae.
Diodora aspera, also known as the rough keyhole limpet, is a species of sea snail, a marine gastropod mollusk in the family Fissurellidae, the keyhole limpets. Although similar in appearance to a common limpet, it has a hole near the apex of its shell, and is only distantly related. It often has a scaled polychaete worm Arctonoe vittata living inside its shell as a commensal. In the event that it is attacked by a starfish, it extends flaps of mantle to defend itself, and the worm also helps drive the predator away.
