Shall I dispose of the dandy first? Perhaps it were better so, for I confess to a very slight acquaintanceship with him, and as I am ignorant, too, of its ceremonious as well as familiar title, the pleasure of a formal introduction is denied. In the portrait the ruling passions--modesty and meekness--are graphically displayed. When it lies close--and it moves rarely, and then with a gentle lateral swaying--the fancy dress of seaweed is a garment of invisibility. It is far more true to character alive than as a museum specimen, for its natural complexion is a yellowish grey, the neutral tint of the blending of sand and coral mud upon which it resides. The preserving fluid added a pinkish tinge to the body and limbs. Blame, therefore, the embalmer for the over-conspicuous form which is not in the habit of the creature as it lived. Neither are the plumes those of pomp and ceremony, but merely the insignia of self-conscious meekness--the masquerade under which the shrinking crab moves about, creating as little din and stir as possible, in an ever-hungry world. With such unfaltering art does it act its part that it is difficult to realise the crab's real self unless aided by mischance. Conscious of the terrors of discovery, it rocks to and fro, that its plumes may sway, as it were, in rhythm with the surge of the sea. Can there be such a thing as an unconscious mimic? If not, then the portrait is that of an ideal artist. Those who know only the great flat, ruddy crabs with ponderous pincers and pugnacious mien, which frequent fish shop windows, can form but a very unflattering opinion of the fancy varieties which people every mile of the Barrier Reef. The struggle for existence in this vast, crowded, and most cruel of arenas is so appalling that the great crab family has been battered by circumstances into weird and fantastic forms. Only a few come up to the human conception of the beautiful either in figure or colouring. While some shrink from observation, others, though themselves obscure to the vanishing-point, seem to be endowed with a vicious yearning for notoriety. A certain cute little pursuer of fame is absolutely invisible until you find it stuck fast to one of your toes with a serrated dorsal spur a quarter of an inch long. It is invisible, because Nature sends it into this breathing world masquerading, as she did Richard III, deformed, unfashioned, scarce half made-up. In general appearance it closely resembles a crazy root-stalk of alga--green and not quite opaque, and clinging to such alga it lives, and lives so placidly that it cannot be distinguished from its prototype except by the sense of touch. When you pick it gingerly from between your toes there is a malicious gleam in the pin-point black eyes, and then you understand that it is one of the many inventions designed for the torment of trespassers.
