Most species live in holes among the rocks, attached to stones or shells, over which they slide in a clumsy manner. They are especially fond of deep dark grottoes, and when they have taken full possession of such a place, they may be found clinging to the sides and roof of the cave, and displaying their charms without reserve. Although they do not enjoy the glare of the bright sun, they expand best in mild, clear weather, and remain closed when the sea is rough and stormy.
A few of these animals float on the ocean. One sea-anemone is fond of a roving life, and having no very good means of travelling about, it attaches itself to the back of a certain kind of crab, and accompanies the crab in all its wanderings. There seems to be an attraction between the two, and one is rarely seen without the other.
Another species is mostly found clinging to the shell of a whelk, but for certain good reasons it never clings to a living one. The whelk burrows in the sand. This would be disagreeable and inconvenient to the anemone, so it prefers a dead shell which has been taken possession of by a hermit-crab, and henceforth travels about with the crab. We would scarcely look for affection in a crab, but it has been said that the hermit grows fond of its companion, and that when it has outgrown its shell and has selected a new one, it will carefully lift the anemone from the old home and place it on the new one, "giving it several little taps with its big claws to settle it."
I hope that none of you will fail to hunt up these lovely rock pools when you have an opportunity. The pleasure of a visit to the sea-shore is greatly increased by an interest in the strange forms of animal life which we see there and nowhere else. A glass jar filled with sea-water is often a source of great delight. In it you may drop any strange-looking object that has excited your curiosity. Perhaps this strange object may prove to be some odd little animal which is not yet dead, but which will revive with the touch of the life-giving water.
Most of these animals are timid, but they will expand when they are left perfectly still. In this way we may watch their habits and their hidden beauties. Sea-anemones do nicely in such an aquarium, and as they cling to the side of the jar, we can observe all parts while they are in action. By far the pleasantest way to learn about them is to let them tell their own story. The water must be changed frequently, for impurities are constantly passing from the bodies of even these delicate animals. They will soon die if placed in fresh-water.
