The taxonomic term Bivalvia was first used by Linnaeus in the 10th edition of his Systema Naturae in 1758 to refer to animals having shells composed of two valves. [3] More recently, the class was known as Pelecypoda, meaning "axe-foot" (based on the shape of the foot of the animal when extended).
In several major drug classification systems, these four types of classifications are organized into a hierarchy. [4] For example, fibrates are a chemical class of drugs (amphipathic carboxylic acids) that share the same mechanism of action ( PPAR agonist ), the same mode of action (reducing blood triglyceride levels), and are used to prevent ...
Conus magus is an example of a cone snail that has a poisoned harpoon-like projectile which it uses to paralyze prey like small fish. [4] Some organisms, like the Viperfish, are believed to attract small fish or prey by using its photophore. [5] Many different marine organisms have been explored for bioactive compounds.
In 2010 a new proposed classification system for the Bivalvia was published by Bieler, Carter & Coan revising the classification of the Bivalvia, including the subclass Pteriomorphia. [8] However, the following taxonomy represents the current accepted arrangement of this subclass according to the World Register of Marine Species [ 9 ]
Drug nomenclature is the systematic naming of drugs, especially pharmaceutical drugs.In the majority of circumstances, drugs have 3 types of names: chemical names, the most important of which is the IUPAC name; generic or nonproprietary names, the most important of which are international nonproprietary names (INNs); and trade names, which are brand names.

Protobranchia is a subclass of bivalve molluscs. [1] It contains the extant orders Nuculanida, Nuculida, and Solemyida.. These are deep water clams of a small and primitive order with a taxodont hinge (composed of many similar, small teeth), generally with a central ligament pit, large labial palps which are used in deposit feeding and the gills used only for respiration, the anterior and ...

In general, freshwater bivalves have predators such as raccoons, otters, some species of fish, and some species of turtles. Droughts, floods, and heat waves are a few examples of major climatic events that are happening more frequently because of the global changing climate. This is a huge killer of freshwater bivalve populations. [11]
