Identification of Living and Fossil Bivalve Larvae

Early Stage Biomineralization in the Periostracum of the ‘Living Fossil’ Bivalve Neotrigonia

A detailed investigation of the shell formation of the palaeoheterodont 'living fossil' Neotrigonia concentrated on the timing and manufacture of the calcified 'bosses' which stud the outside of all trigonioid bivalves (extant and fossil) has been conducted. Electron microscopy and optical microscopy revealed that Neotrigonia spp. have a spiral-shaped periostracal groove. The periostracum itsel...

Not a “living fossil:” the eastern Pacific bivalve Tellidorella belongs with Lucinidae, not Cardiniidae

Tellidorella (type species: T. cristulata) is a small eastern Pacific bivalve presently classified in the Cardiniidae, a family otherwise known as fossils from the Paleozoic and early Mesozoic. Evidence from shell characters including external sculpture, hinge teeth, and adductor muscle scars suggests a more appropriate placement in the subfamily Myrteinae of Lucinidae. This is the first record...

Machine Learning and Multiscale Methods in the Identification of Bivalve Larvae

This paper describes a novel application of support vector machines and multiscale texture and color invariants to a problem in biological oceanography: the identification of 6 species of bivalve larvae. Our data consists of polarized color images of scallop and other bivalve larvae (between 2 and 17 days old) collected from the ocean by a shipboard optical imaging system of our design. Larvae ...

Investigation of the various factors in destruction of living and fossil corals in Persian Golf

Single - step species identification of bivalve larvae using multiplex polymerase chain reaction

One of the biggest obstacles to studying recruitment variation in marine bivalves is the need to collect and process large numbers of plankton samples. Larval bivalves are notoriously difficult, if not impossible, to identify to species using morphological criteria alone. Remote time-series collections could satisfy the sampling challenge, but efficient identification techniques must be develop...
