Cryptic species are a common phenomenon in cosmopolitan marine species. The use of molecular tools has often uncovered cryptic species occupying a fraction of the geographic range of the original morphospecies. Shipworms (Teredinidae) are marine bivalves,

The Teredinidae possess specialised calcareous paddle-like structures, the pallets, which flank the siphons. The external segmentation/non-segmentation of the pallets is used as the main diagnostic character to distinguish between the Teredininae (non-segmented
