Bivalvia (/ b aɪ ˈ v æ l v i ə /) or bivalves, in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class of aquatic molluscs (marine and freshwater) that have laterally compressed soft bodies enclosed by a calcified exoskeleton consisting of a hinged pair of half-shells known as valves.
This is a list of the marine bivalves recorded from Ireland. It is part of the List of marine molluscs of Ireland. The list includes species from the continental margin (200–500m), bathyal zone (500–2000m), and abyssal zone (2000–4000m), in the Rockall Basin, Porcupine Seabight, and Celtic Sea.
The longest marine bivalve, Kuphus polythalamia, was found from a lagoon near Mindanao island in the southeastern part of the Philippines, which belongs to the same group of mussels and clams. The existence of huge mollusks was established for centuries and studied by the scientists, based on the shells they left behind that were the size of ...

Lucinella divaricata, the divaricate lucine, is a small marine bivalve mollusc of the family Lucinidae found in the north eastern Atlantic and the Mediterranean. Its fossils are known from Cenozoic deposits all over Europe. [1] Chemoautotrophic bacteria in their gills enable them to survive well in substrates rich in hydrogen sulfide. [2]
Plebidonax deltoides or Donax deltoides is a small, edible saltwater clam or marine bivalve mollusc, endemic to Australia. It belongs to the family of either the Donacidae, or the related Psammobiidae. It is most widely known as the pipi (also spelled pippi, plural pipis or pippies) in the eastern states of its native Australia.
Good evidence exists for the appearance of marine gastropods, cephalopods and bivalves in the Cambrian period . However, the evolutionary history both of molluscs' emergence from the ancestral Lophotrochozoa and of their diversification into the well-known living and fossil forms are still subjects of vigorous debate among scientists.
