The Atlantic and Pacific coasts abound in several species of interesting starfishes, several of which are illustrated on the plate. The most numerous of these is the common five-finger (Asterias forbesii), found abundantly on the shores of the New England states. This animal loves to hide among the rocks and seaweed, and a search at low tide will always reveal a host of them. Along the sandy shores of Narragansett Bay they may be collected at low water among the seaweed, where they feed upon bivalve mollusks, such as cockles, arks and clams.
One of the largest and handsomest of the starfishes is the Giant Mountain Starfish (Oreaster reticulatus), so common in the waters of the Bahama Islands. This species attains a diameter of fifteen or sixteen inches and is very high in the center. Its upper surface is reticulated by the crossing of the hard parts of the skeleton, and beautiful ornaments may be made by removing the softer parts and leaving only the skeleton, which forms a peculiarly latticed framework. This species is found on both sides of the Atlantic ocean; it is a common starfish in the West Indies, inhabits the coast of the United States from Florida to South Carolina and is abundant on the shores of the Cape Verde Islands.
The most common starfish of the Pacific coast is the Ochre-colored Starfish (Asterias ochracea), which ranges from Sitka, Alaska, to San Diego, California, the last mentioned locality being one of the best. It is a large species, frequently attaining a diameter from tip to tip of the arms of sixteen inches. When alive it is of a rich ochre color or brown, and the surface is beautifully reticulated by numerous club-shaped spines arranged in rows. This species is as much an enemy to the oysters of the Pacific coast as is the common five-finger to those of the Atlantic coast.
Another common starfish of the coast of California is the Vermilion Starfish, which may be collected by thousands at San Diego and Monterey. The body is very broad and the rays short and wide. It is in shape quite suggestive of the foot of a pelican or duck. The upper surface is beset with small, heavy spines, which are arranged in little festoons on the five rays. Its name is very appropriate, for it is of a rich vermilion color, varying from this to rose, yellowish or purple.
