Hemimarginula pumila, the pygmy ermarginula, is a species of sea snail, a marine gastropod mollusk in the family Fissurellidae, the keyhole limpets. [1] [2]
The whitish to pale brownish conical shell is 6 to 13 mm long on a broadly oval base with an irregularly scalloped margin. The height is variable and the shell is usually much depressed. The apex is nearly centrally located. There is a narrow exhalant slit at the front margin. There are about twelve broad ribs that are minutely scabrous. These ribs are crossed by three buff, radiating bands. The radiating ribs are distant and corrugated. The interstices are deeply latticed and corrugated.
This keyhole limpet is fairly common and can be found on or under rocks in tide pools, shallow water and in the intertidal to the sublittoral zone (from 2m to 27 m deep) along the coasts of Southeastern Florida south to Brazil. They can also be found living on mangrove oysters. [3]
This species occurs in the following locations: [1]
Fissurellidae, common name the keyhole limpets and slit limpets, is a taxonomic family of limpet-like sea snails, marine gastropod molluscs in the clade Vetigastropoda. Their common name derives from the small hole in the apex of their cone-like shells. Although superficially resembling "true" limpets, they are in fact not closely related to them.
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.
Kermia daedalea is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae.
Neodrillia albicoma is a species of sea snail, a marine gastropod mollusk in the family Drilliidae.
Entemnotrochus adansonianus, common name Adanson's slit shell, is a species of sea snail, a marine gastropod mollusk in the family Pleurotomariidae.
Engoniophos unicinctus is a species of sea snail, a marine gastropod mollusk in the family Nassariidae.
Puncturella asturiana, common name the hawk puncturella, is a species of sea snail, a marine gastropod mollusk in the family Fissurellidae, the keyhole limpets.
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.
Fissurella barbadensis is a species of limpet in family Fissurellidae, the keyhole limpets. It is known commonly as the Barbados keyhole limpet and the rugose slit limpet. This species is native to the western Atlantic Ocean, including many islands of the Caribbean.
Lucapinella limatula is a species of sea snail, a marine gastropod mollusk in the family Fissurellidae, the keyhole limpets.
