Although closely related to bay scallops, calico scallops (Argopecten gibbus) live in deeper, offshore waters along the east and west coasts of Florida.Calico scallops are found on sandy or shelly bottoms, and their mottled pink-hued shells commonly wash ashore, providing beachgoers with colorful treasures. The fossil members of the stock include the ancestors of these living species together with Argopecten eboreus (Conrad), an extinct species or species-group not ancestral to any of the later taxa.

Evolution from its origin has resulted in a successful and diverse group: pectinids are present in the world's seas, found in environments ranging from the intertidal zone to the hadal depths. sl = nl[0]; , This common fossil has existed over a very long geological time and still lives today! Pecten gibbus fossils appear extremely similar to the seashells that we often find lying on the beaches, which show how the evolution of shell started about 2 million years ago.

On the basis of the materials analyzed thus far, the evolution (both phyletic change and splitting) of the stock has been faster on the Atlantic side of the Americas than on the Pacific side, with the living Pacific species resembling late Miocene and early Pliocene Atlantic species. Pectinidae, a large group of marine bivalves comprising more than 300 species worldwide, inhabit a diverse array of habitats, enabling an enormous radiation, and yielding many different life forms and adaptations.

In certain features of morphology, the A. gibbus lineage is convergent on the A. eboreus lineage, indicating that the extinct species may also have been restricted to open marine waters. window.rs_init_css.innerHTML += "#"+e.c+"_wrapper { height: "+newh+"px }"; Alternative combinations: Aequipecten gibbus, Chlamys (Plagioctenium) gibbus, Ostrea gibba, Pecten (Chlamys) gibbus, Pecten (Plagioctenium) gibbus, Pecten gibbus. During the Pleistocene, A. nucleus, a tropical bay scallop, is inferred to have split from A. gibbus and to have become morphologically convergent on the true bay scallop, A. irradians.

Select the purchase Its performance was assessed by larval survival rate, shell growth, settlement rate and post-larval shell growth for the duration of larval life (13 days). Some evidence suggests that fall spawns may be crucial to maintaining standing stocks of calico scallops. The postulated phylogeny shows a poorly known species, Argopecten species b, in the early middle Miocene (Oak Grove Sand), that is apparently very near the origin of the stock. Cambridge Journals publishes over 250 peer-reviewed academic journals across a wide range of subject areas, in print and online. The living Pacific A. circularis is morphologically primitive in that it resembles the Miocene species A. comparilis more than it does any of the later species on the eastern side of the Americas and is ecologically primitive in that it is broadly adapted and able to live both in bays and sounds and in open marine waters.
