The family Pectinidae, whose name derives from the Latin pecten meaning comb, refers to a comb-like structure on the shell.[1] Scallop shells are a common sight on beaches and are popular collectibles due to their beauty.[2] Among marine bivalve families, Pectinidae ranks as one of the largest, with more than 300 living species distributed across 60 genera.[3]

Key facts and history

Pectinidae was the most diverse bivalve family in the Mesozoic era but nearly disappeared by the end of the Cretaceous.[4] They have a single central adductor muscle, which is larger and more developed than that of oysters.[5] The family is unusual in including dioecious, simultaneous hermaphrodite, and protoandrous hermaphrodite members.[5] During the Tertiary, the surviving lineages underwent rapid speciation.[6]

For both fossil and recent Pectinidae, roughly 7,000 species and subspecies names have been proposed.[6] Scallops are found in every ocean worldwide, with the Indo-Pacific region hosting the greatest number of species.[7] The typical depth range for most species extends from the low tide line down to 100 meters.[7] As filter feeders, scallops consume plankton and, unlike many bivalves, do not have siphons.[5]

Two types of adductor muscle are present in scallops: a fast striated type and a slow smooth type.[8]

What the cited sources add

The NOAA technical memorandum by Hart notes that New Bedford, Massachusetts, is a consistently high-value port due to the lucrative scallop fishery.[9] The same source states that research surveys evaluate the health of over 50 fisheries from Maine to North Carolina.[9] The book "Scallops" published by Elsevier Science in 2006 has 1500 pages.[10]
