Genomics
A chromosome-level genome assembly of Meretrix lamarckii was published in 2026, providing the first reference genome for the species. The genome is approximately 890.5 Mb in size and comprises 19 pseudo-chromosomes. The assembly has a BUSCO completeness of 99.5% and contains 33,346 predicted protein-coding genes.[3]
Ecology
It is a medium-sized clam which lives in sandy sediments from the subtidal zone to a depth of 20 meters.[4] In the waters off Hyūga, Miyazaki, it spawns between late July and early September.[5]
Relationship to humans
M. lamarckii is edible and economically important in China; commercial fishing has greatly disrupted the habitat where it lives.[4][6] It is a filter feeder which primarily feeds on phytoplankton.[7] Its shell is used to make the white stones used in Go.[5]
