Comparison between the heterodont fibrillar prisms described herein and the calcite prisms found in these pteriomorph bivalves reveal distinct differences.
A molecular phylogeny of heterodont bivalves (Mollusca: Bivalvia: Heterodonta): new analyses of 18S and 28S rRNA genes.
It is of interest that recent molecular analyses of the phylogenetic relationships of the heterodont bivalves have shown that many of these taxa lie close to the trigonoids and unionoids within the Palaeoheterodonta and the Anomalodesmata within the basal Heterodonta (Taylor et al., 2007).
Despite displaying a broad range of morphologies, which correspond to widely varying life habits, the constituent families have been shown by molecular analyses to form a monophyletic clade within the basal heterodonts (Giribet and Wheeler, 2002; Giribet and Distel, 2003; Harper et al., 2006; Taylor et al., 2007).
The distribution revealed in Figure 13 suggests that the occurrence of periostracal spikes may be considered a synapomorphy for either the Anomalodesmata or some larger clade of basal heterodonts, and that absence in the Pandoridae, Cleidothaeridae, and certain lyonsiid and laternulid species may be interpreted as character losses.
Sphaerid and corbiculid clam represent separate heterodont bivalve radiations into freshwater environments.
In the heterodont branch, a clade including the families Tridacnidae and Cardiidae - and comprising all of the zooxanthellate clams examined, as well as two azooxanthellate clams, V.
Sphaeriid and Corbiculid clam represent separate Heterodont bivalve radiations into freshwater environments.
The life cycle of Baccigerinae involves a heterodont bivalve, which acts as first intermediate host, some representative of gelatinous plankton or a crustacean usually act as second intermediate hosts and fishes are the definitive host (Bray 1988).
Nerve fibers have been observed, from time to time, in the eulamellibranch gills of heterodonts like Mercenaria mercenaria, (e.g., Ensis siliqua in Arkins, 1937), but the innervation of such gills has not been described.
