The soybean plant is called a legume because it produces a bivalve pod or fruit.
Additional studies are required to resolve questions of vitellogenin regulation and the role of estrogens in bivalve molluscs.
The bean seed grows in a bivalve pod called a legume.
However, as early as 1923 Collip reported finding insulin-like activity in a bivalve mollusc, Mya arenaria.
The hinge ligament of bivalve shell is an example of a complex development.
A bivalve closes its shells by contracting its powerful adductor muscles.
Other species take refuge in a protective structure surrounding their body, such as polychaete tubeworms, caddis fly larvae, gastropod and bivalve mollusks, hermit crabs, barnacles, turtles, and armadillos.
These and other studies from native habitats have demonstrated that green crabs have a broad diet range, but that bivalve molluscs generally make up the largest part of their diet.
In bivalve molluscs, growth rate of the shell tends to decelerate with growth and the shell generally becomes more inflated in the late growth stage.
The only bivalve group having comparable hinge features is the Philobryidae (Arcoida, Limopsoidea).
