The Kapis shell (Placuna placenta), better known as lampirong to the Ilonggos is a bivalve mollusk with translucent shells and a very small body. Wild stocks of this shell used to abound in the coastal waters of Oton and Tigbauan. Its economic importance to the country reflects a whooping US $35 M worth of fishery exports in 1991, the fifth in the rank.
