The crustacean shown in figure X.3 is an extremely decorative ornament. A single horn is sufficient to manufacture it. Some artisans may, however, prefer to use several horns, thus combining different colours in the same crustacean. Figure X.4 is an exploded view of the various parts of the crustacean, in position for assembling.

Claws "B" and "C", legs "D" and antennae "E" are bonded in holes drilled for this purpose in the body "A". The tail fan "F" is bonded into a slit cut at the rear of the body "A". The eyes "G" are generally made from round grains. If these are not available, they may be cut in horn, then bonded into depressions hollowed out in the front end of the body.

The diagrams in figure X.5 give the basic dimensions of the most complex parts.

It should be noted that the two claws "B" and "C" are symmetrical but not identical. They have the same dimensions.

The antennae are 5 mm in diameter at the point where they are bonded to the body. They become thinner towards the other end. Their overall length is approximately 250 mm. The legs have a diameter of 5 mm. Their total length is about 140 mm.

The veins and round markings on the tail fan and the rings on the tail are engraved in the horn.
