. Sea-shore life; the invertebrates of the New York coast. Marine animals. THE CRUSTACEANS 93. Fig. Oo: IIKHMIT CRAH. Knui] Aie. Sliowing the liorr'tnved shell rovered Willi sea weeds ahd HydracHnia. Cape Ann, Mass. the crab instantly witlidraws witliin its shell, completely closing the opening with its claws, whicli arc of the exact shape retpiired for the purpose. As the crab grows it . must occupy larger and larger shells. These are apparently selected with coii- sideraljle care, but liiuiiig decided upon it tlie crab finally darts into its new abode with almost incredible rapidity. in common witli other crustaceans tliese craljs are scavengers. • They are also inveterate fighters, and will conquer and devour one another when opportunity offers. A niunljer of marine animals grow upon the sliells, which are carried^aliout by hermit crabs, thus obtaining the advan- tages of a Avandering life. Several species of hydroids. such as Uydractinia, cover the shells with soft, pink-white, velvety- looking growths, while anum- Ijer of sea anemones also live u])on the shells. One of these called ( Epizoanllms iivierica- 7iiisJ finally dissolves the shell, forming a cavity within which the cral) continues to reside. One of the most interest- ing of the hermit crabs is the Robber Crab (Birgun lolroj of the tropical Pacific Islands. It is about two and a half feet long, and the abdomen is soft below but protected above by hard plates. It lives within deep burrows, and only occasionally visits the water. It crawls to tlie top of the cocoanut trees, and tears open the nuts for the sake of the white "meat.".
