Pectinida is a taxonomic order of large and medium-sized saltwater clams, marine bivalve molluscs, commonly known as scallops and their allies. [1] . It is believed that they began evolutionarily in the late Middle Ordovician epoch; many species, of course, are still extant. [2]

Scallop (/ ˈ s k ɒ l ə p, ˈ s k æ l ə p /) [a] is a common name that encompasses various species of marine bivalve mollusks in the taxonomic family Pectinidae, the scallops.

2025年1月24日 · scallop, any of the marine bivalve mollusks of the family Pectinidae, particularly species of the genus Pecten. The family, which includes about 50 genera and subgenera and more than 400 species, is worldwide in distribution and ranges from the intertidal zone to considerable ocean depths.

2024年5月27日 · Scallops eat plankton and krill by filtering ocean water. These mollusks are actually an entire family, known as Pectinidae, that includes over 300 species. Scallops have as many as 200 eyes, which they use to monitor their environment for potential predators, food sources, and other changes.

Common name: True scallops. Key morphological features: The Pectinidae range in size up to ~300-500mm. The shells are often thin, equivalve or inequivalve, with inequivalve species most often having a more inflated right valve (which is usually …

The Pectinoidea are a superfamily of marine bivalve molluscs, including the scallops and spiny oysters. [1] All members of this superfamily have a triangular resilium with a nonmineralized medial core that functions below the hinge line. [2]

Scallop is a common name that is primarily applied to any one of numerous species of saltwater clams or marine bivalve mollusks in the taxonomic family Pectinidae, the scallops.

2019年8月1日 · Scallops (Pectinidae) are one of the most diverse families of bivalves and have been a model system in evolutionary biology. However, in order to understand phenotypic evolution, the Pectinidae needs to be placed in a deeper phylogenetic framework within the superfamily Pectinoidea.

2008年9月1日 · Evolutionary relationships of the Pectinidae were examined using two mitochondrial genes (12S rRNA, 16S rRNA) and one nuclear gene (Histone H3) for 46 species. Outgroup taxa from Propeamussidae, Spondylidae and Limidae were also sequenced to examine the impact of outgroup choice on pectinid topologies.

2006年5月12日 · Pectinids constitute one of the most conspicuous groups of marine bivalves, and include some of the most important species from the point of view of fisheries and aquaculture. In spite of this, their systematics and evolution are not well understood.
