Cuttle is the name for the whole race of cephalopods, and is supposed to be a corruption of the word cuddle, in the sense of hugging.

They are curious creatures, the one who favoured us with a good view of him being very like a loose red velvet pincushion with eight legs, and most of the bran let out.

Yet this strange, unshapely creature has a distinct brain in a soft kind of skull, mandibles like a parrot, and plenty of sense.  His sight, hearing, touch, taste, and smell are acute.  He lies kicking his legs in the doorway of his favourite cavern, which he selected for himself and is attached to, for a provokingly long time before he will come out.  When he does appear, a subdued groan of gratified expectation runs through the crowd in front of his window, as head over heels, hand over hand, he sprawls downwards, and moves quickly away with the peculiar gait induced by having suckers instead of feet to walk with.

Tank 15 contains eels.  It seems to be a curious fact that fresh-water eels will live in sea-water.  I should think, when they have once got used to the salt, they must find a pond very tasteless afterwards.  They are night-feeders, as school-boys know well.

Tank 16.  Fish—­grey mullet.  Tank 17.  Prawns.

If with the fishes we had felt with friends, and with the lobsters as if with hobgoblins, with the prawns we seemed to find ourselves among ghosts.

A tank that seems only a pool for a cuttle-fish, or a cod, is a vast region where prawns and shrimps are the inhabitants.  The caves look huge, and would hold an army of them.  The rocks jut boldly out, and throw strange shadows on the pool.  The light falls effectively from above, and in and out and round about go the prawns, with black eyes glaring from their diaphanous helmets, in colourless, translucent, if not transparent armour, and bristling with spears.

“They are like disembodied spirits,” said my husband.

But in a moment more we exclaimed, “It’s like a scene from Martin’s mezzo-tint illustrations of the Paradise Lost.  They are ghostly hosts gathering for battle.”

This must seem a most absurd idea in connection with prawns; but if you have never seen prawns except at the breakfast-table, you must go to the Great Aquarium to learn how impressive is their appearance in real life.

The warlike group which struck us so forcibly had gathered rapidly from all parts of the pool upon a piece of flat table-rock that jutted out high up.  Some unexplained excitement agitated the host; their innumerable spear-like antennae moved ceaselessly.  From above a ray of light fell just upon the table-rock where they were gathered, making the waving spears glitter like the bayonet points of a body of troops, and forming a striking contrast with the dark cliffs and overshadowed water below, from which stragglers were quickly gathering, some paddling across the deep pool, others scrambling up the rocks, and all with the same fierce and restless expression.
