So far I have never seen this lovely lodger in the same anemone with the painted fish. The latter, perhaps, admires it too ardently and literally. Another marvel, the sea-hare (APLYSIA), is a crudely wedge-shaped body but incomparable in its ruggedness to that or any other model, and the colour of mud and sand and of coral, dead and sea-stained. It reposes, with its back flush with the surface, beside a block of coral or stone defiantly indistinguishable from the ocean floor--a stolid, solid, inert creature, eight or ten inches long, the under part smooth, presenting the appearance of wet chamois-leather, and irresponsive to touch--"the mother tongue of all the senses." Ugly, loathsome, and tough of texture, it is so helpless that if it is placed on the sand it is extremely doubtful whether of its own volition it could regain its natural position. The surge of the sea might roll it over, and it might then be able to regain the grovelling attitude essential to life. Otherwise, I am inclined to think fatal results would follow the mere placing of the creature sideways on the sand. It seems to possess but the feeblest spark of life, and yet it has its sentiments and love for its kind, for often three or four are huddled together. And how, it may be asked, is this creature, so apt at concealment and so completely disguised, made visible to human eyes? The answer is that if by chance the animal is disturbed it makes a supreme effort at further concealment, and that impulse--perfect as it may be when set in opposition to the wit of the creature's nervous and apprehensive enemies--reveals it most boldly to man. From a funnel-shaped opening between two obscure flaps on the back--ordinarily invisible--there is emitted a gush of liquid, royal purple in hue, which stains the sea with an impenetrable dye for yards around. The colour, which is delightfully gorgeous, mingles with the water in jets and curling feathery sprays, enchanting the beholder with unique and ever-changing shapes until a glorious cloud is created and he forgets the ugliness and forgives the humility of the originator in the enjoyment of an artistic treat. If the cloud which Jupiter assumed was of the imperial tone and of the fascinating fashion which the groveller in the mud creates, Aegina would have been superfeminine had she not joyously surrendered. Between the neutral tints of the squalid sprawler and the fluid which it excretes the contrast is so surprising that one involuntarily raises his hat by way of apology for any slighting thoughts which may have arisen from first and imperfect acquaintance. There are grounds for the entertainment of the belief that the ejected fluid not only effectually conceals the scarcely discernible animal but that it harshly affects the sensibilities of fish.
