Taxonomy

This species was described in 1856. It was thought that this species was a taxonomic synonym to Tridacna maxima however it was recognized later on as its own separate species.[4]

It is a sister species of Tridacna squamosina. These two species are then a sister lineage to Tridacna rosewateri.[3]
