Possible Misidentifications

In western North America, this species is often confused with Protothaca staminea, however, V. philippinarum shells are more elongate than P. staminea. Internally, V. philippinarum has yellowish valves, with a purple suffusion near the posterior margin. Protothaca staminea lacks this purple suffusion. This species may be found together with Protothaca staminea, but tends to reside at slightly higher tide levels.
