(See diagram.)
The lobster is all over grey-coloured, with a mottling of black.
Its under or hinder feet, up to the big feet or claws, are eight in
number; then come the big feet, far larger and flatter at the tips
than the same organs in the crawfish; and these big feet or claws
are exceptional in their structure, for the right claw has the extreme
flat surface long and thin, while the left claw has the
corresponding surface thick and round. Each of the two claws,
divided at the end like a pair of jaws, has both below and above a set
of teeth: only that in the right claw they are all small and
saw-shaped, while in the left claw those at the apex are saw-shaped
and those within are molar-shaped, these latter being, in the under
part of the cleft claw, four teeth close together, and in the upper
part three teeth, not close together. Both right and left claws have
the upper part mobile, and bring it to bear against the lower one, and
both are curved like bandy-legs, being thereby adapted for
apprehension and constriction. Above the two large claws come two
others, covered with hair, a little underneath the mouth; and
underneath these the gill-like formations in the region of the
mouth, hairy and numerous.
