Lobster shells turn bright red-orange when boiled. The American lobster # 8217 ; s organic structure has 21 sections. The caput has 6 sections ; the thorax # 8211 ; the centre portion # 8211 ; has 8 ; and the venters # 8211 ; the tail portion # 8211 ; has 7.

The 5th brace, which extends in forepart of the caput, are thick and terminal in big claws. The larger of these two claws has thick dentitions to oppress quarry. The smaller claw has crisp dentitions to rupture nutrient apart. All lobsters do non hold the heavy claw on the same side. Some are right-handed and left-handed.
