but come to the seashore at certain seasons to lay their eggs in the
sand. When once they have started on their march to the sea nothing
can turn them aside from the path in which they are traveling.

Another cousin of the Hermit lives in the East and West Indies. It is
called the "Calling Crab," because it has a very large claw which it
holds above its head when running, and this gives it the appearance of
beckoning to some one. This Calling Crab makes its home in holes, or
burrows on land.

Still another land relation is the East India Cocoa-Nut Crab, which
lives upon the cocoanuts that fall from the trees. With its large,
heavy claws it tears the husk from the cocoanut, and makes a hole in
the nut, and takes out the meat. These crabs also make their homes in
deep burrows, which they line with the husks and fibres from the
cocoanuts. Though a land crab the Cocoa-Nut cousin is fond of the sea,
and takes a bath in it every night. These crabs grow to a very large
size.

Crabs, and all crustaceans multiply enormously, and are of all sizes
from very tiny ones to one respectable Japan crab which covers
twenty-five feet of ground. In the tropics they grow very large, and
are of many different varieties.

Some crabs live in fresh water rivers and streams, some of the lower
forms of the family in the extreme North, and others in dark,
under-ground caves.
