Claim: The chione cancellata's taxonomic status was radically revised in 2000, since it was originally thought to be two separate species which are strictly Caribbean ( a region of the Americas that consists of the Caribbean Sea) in distribution.
Evidence: What had previously been thought to be one species was discovered to be a "cryptic species pair" and as such it was divided into two separate species, on the basis of morphological, morphometric and phylogenetic analyses.
