Glimpses of Ocean Life; Or, Rock-Pools and the Lessons they Teach

In the first place, the crab would not, if he could help it, allow
himself to be handled even in the most gentle manner. To overcome
this difficulty the shell had to be broken. This was done; but, alas!
the shock nearly killed the poor little Hermit. After some trouble,
I carefully unwound his body from the whirls of the Top Shell, and
proceeded to perform the intended operation. Reader, have you
ever seen a child take a rose-bud in his hands, and force open its
half-pouting blossom, in the belief that by so doing he was assisting
nature? If so, you must have watched the puzzled expression of the
boy's countenance when he beheld the leaves fall one by one at his
feet, and the bud itself exhibit evident signs of approaching decay.
In just such a position did I stand with regard to the poor
Hermit-Crab, for, in spite of all my care in manipulation, the skin
of the animal was so tender and delicate that the first gentle pinch
caused a puncture which proved fatal; and as to drawing off the
covering, the thing I now believe to be impossible, even under the most
favourable circumstances.
The upper portion of the Soldier-Crab, I may mention, is cast off in
one piece, while the animal is seated in its turbinated dwelling. The
act is performed with the most perfect ease. Unlike the _Brachyura_,
the _Anomoura_ do not exhibit signs of such rapid growth immediately
after exuviation, but increase in size very gradually indeed.
CHAPTER VII.
Prawns and Shrimps.
'Men holden ye therefore prophanes
Ye eaten neither shrimps nor pranes,'
VII.
Although abundant at many parts of the Scottish coast, at Cockburnspath
(situated near the mouth of the Frith of Forth) only, has the writer
met with the very beautiful prawn, _Palæmon Squilla_. At this locality
specimens were very frequent in rock-pools situated near the shore, nor
were such difficult to capture. The small net being placed cautiously
over their head, the animals did not show signs of resistance, until
they found themselves, by a sudden jerk of the hand, drawn bodily out
of the water. Then, indeed, unless some degree of skill was used, the
captives would give a powerful spring, and escape, from the confinement
of the net, to the more congenial element from which they had been so
unceremoniously ejected.
Prawns (_Palæmonidæ_) exuviate very frequently, in some instances as
often as once or twice a month. No sooner is one coat thrown off and
the Palæmon recovered from the weakness which the process occasions,
than it commences, at first at intervals, and then almost incessantly
day and night, preparations for a renewal of the wonderful operation.
