The 22 pages that link to Bivalvia, each with the reason it gives.

• Permian–Triassic extinction eventRelated: Bivalves suffered losses but later diversified in recovering marine ecosystems.

• MolluscaBroader topic: Bivalves show a distinct body plan adapted to filter feeding and burrowing.

• RadulaCompared with: Bivalves feed without the toothed ribbon found in most other mollusks.

• GastropodCompared with: Bivalves contrast with the usually single-shell, head-bearing gastropod body plan.

• MolluskBroader topic: Bivalves filter food and lack the radula found in most other mollusks.

• ByssusNarrower topic: Many byssus-producing mollusks belong to this class.

• Mazon Creek fossil bedsRelated: Mazon Creek concretions preserve diverse bivalves from the ancient ecosystem.

• BrachiopodCompared with: Bivalves are often mistaken for brachiopods, but their shell symmetry and anatomy differ.

• ShipwormNarrower topic: Shipworms retain the defining paired shell valves of bivalves in highly reduced form.

• Freshwater pearl musselNarrower topic: The freshwater pearl mussel is a bivalve with a two-part shell.

• Sea snailCompared with: Bivalves are marine mollusks, but their body plan differs sharply from gastropods.

• PlacodontiaRelated: Many placodonts ate shelled mollusks, especially bivalves.

• AscidiaceaCompared with: Bivalves filter-feed too, but use molluscan gills and shells rather than a tunicate pharynx and tunic.

• GeoduckNarrower topic: Geoducks are bivalves whose paired shells protect a body built around an unusually long siphon.

• Giant clamNarrower topic: The giant clam is a bivalve with two shell valves joined by a hinge.

• LingulataCompared with: Their superficially similar paired valves can obscure the distinct anatomy of lingulate brachiopods.

• Pecten maximusNarrower topic: Its two valves place Pecten maximus among bivalves.

• PinnidaeNarrower topic: Pen shells are bivalves, sharing the paired-valve body plan.

• RudistsNarrower topic: Rudists were a distinctive extinct lineage within this mollusk class.

• Tusk shellCompared with: Bivalves enclose the body between paired valves rather than a single open-ended tube.

• UnionidaNarrower topic: Unionida is one order within this class of two-shelled mollusks.

• VeneridaeNarrower topic: Veneridae belongs to this two-shelled mollusk class.
