Abstract
In identification of juvenile bivalves immediately after settling onto the sea bottom, it is necessary to examine the characters of their hinge apparatus. Several methods hitherto used require several hours to prepare the specimens for observation on morphological features of the hinge. A simple method to examine the features of the hinge is here proposed : Stick a piece of double-sided sticking vinyl tape on a slide glass, cut a triangular slit on the tape, put the specimen onto the cut slit by using a sucker tube, and place the specimen in a correct upright position with a needle with a minute fragment of the tape on the tip.
