In Sea Urchin's Spine.
"The sea urchin is protected by
bony envelop, and this is covered with
numerous sharp spines which project
in all directions. Strange to relate,
a small mollusk frequently hollows
/ out the interior of one of the spines
and uses it as home, thus provid-
| ing for its own safety, as but few dem
liens of the sea would be hardy
enough to attack the armored sea
urchin.
"Along the shores of the North
Atlantic Ocean is found a worm
(Phascolosoma coementarium) which
takes possession of a dead she'll of
some mollusk like the hermit crab,
but as the aperture is always too large
for its body, it builds out the rim of
the aperture until only small, round
opening is left, through which the
worm can stretch forth the anterior
extremity of its body, or withdraw
into the shell it has appropriated for
its dwelling. 1t lives permanently in
its borrowed home, dragging it about
by the powerful contractions of its
il body. The material with which the
worm so skilfully patches out the
she'll so as to construct the mouth
/ thereof is a hard and durable COM
position Of sand and mud, cemented
together by a secretion of the ami
NAL. When the worm grows too
large for its habitation, instead of
exchanging it for larger shell, as
do the hermit crabs, it gradually ex-
tends it's tube outward from the
mouth of the shell.

1.-THE large jelly fishes, which are
found in almost all seas, and which
float at or near the surface in almost
countless numbers, shelter many
marine animals under their umbrella
and among their numerous tentacles.
A small Caranx fish, numerous crus-
taceans, several species of mollusks,
and, strange to relate, even other
jelly fishes, find refuge under this
floating house. One Of the most
curious of these denizens is little,
white shrimp, with enormous lustrous
green eyes, which lives and rears its
family in the sheltering arms Of it's
host. AS the jelly fish kills more
food than it can devour, the shrimp
lives on the remnants.
