A bivalve mollusks of the family Razoridae (illustration). When the two shells are put together, the shell is long and cylindrical, measuring 12 cm in length, 1.5 cm in height, and bulging 1.2 cm. The shell is thin, and its surface is covered with a shiny yellow shell. The apex of the shell is at the front end, which is cut at a slight angle, and the rear end at a right angle. In English, this shape is likened to a razor, and Razor clams are called razor clams or razor shells. Even when both shells are put together, the front and rear ends are open. The inside is grayish white. The soft foot that protrudes from the rear end is large and yellow-orange. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
