First record of the worm snail Eualetes tulipa (Rousseau in Chenu, 1843) in Southeast Asia

Abstract

The Vermetidae is a family of sessile marine gastropods whose members are difficult to identify accurately, but one species, Eualetes tulipa is widely documented as an introduced species globally. In Asia, there is only one known record of this species from India to date. We report the presence of E. tulipa in Singapore based on DNA barcoding. This is the second known record from Asia and the first confirmation of a non-native vermetid for Southeast Asia.
