Perna perna, the brown mussel, is an economically important mussel, a bivalve mollusc belonging to the family Mytilidae. It is harvested as a food source but is also known to harbor toxins and cause damage to marine structures.

Acanthopleura granulata, common name the West Indian fuzzy chiton, is a medium-sized tropical species of chiton. This type of chiton's activity does not depend on spring-neap oscillations leading to lower locomotion loss. Its morphology is different from usual chitons as it has a fifth valve, which is split into halves.
Mopalia ciliata is a chiton in the genus Mopalia, commonly known as the hairy chiton. It is a medium-sized marine mollusc up to 5.0 cm (2.0 in) in length. It is oval shaped with 8 separate, moderately elevated, overlapping ridged valves on its dorsal surface. Hairy chitons can be found along the coast of North America.
Plaxiphora albida, the white Plaxiphora chiton, is a species of chiton in the family Mopaliidae.
Chiton politus, the tulip chiton, is a medium-sized polyplacophoran mollusc in the family Chitonidae, found on the coast of southern Africa.

Barbatia reeveana, the low-rib ark or common Reeve's ark, is a species of bivalve mollusc. It was first described to science by Alcide d'Orbigny in 1846.

Anomia ephippium is a species of bivalve belonging to the family Anomiidae.
Callochiton septemvalvis, the smooth European chiton or smooth mail-shell is a medium-sized species of polyplacophoran mollusc in the family Ishnochitonidae. It was initially described by George Montagu in 1803 and can be found throughout Europe in shallow waters and several seas including the Mediterranean sea.
Stenochiton longicymba, the clasping stenochiton is a species of polyplacophoran mollusc with an elongated shell, in the family Ishnochitonidae. It was first described by Henri Marie Ducrotay de Blainville in 1825 and is endemic to Australia's waters.
Nuttallochiton mirandus is a medium to large-sized species of polyplacophoran mollusc in the family Mopaliidae. It was initially described by the zoologist Johannes Thiele in 1906 and is endemic to Antartica's cold waters.
