101. The land hermit crab, Coenobita 

 nifioxa. of East African coasts, is known 

 asli "soldier ciab" because it hunts in 

 huge numbers, climbing trees and 

 bushes, eating fruits, carrion, and ani- 

 mals slow enough for it to capture. This 

 specimen in the London zoo carried a 

 liorrowed marine snail shell 3!4 inches 

 in length. As the crabs grow they ap- 

 propriate larger snail shells (Ralph 

 Buchsbaum) 



103. The sponge crab, Dromia vulgaiis, 

 carries on its back, like a beret, a con- 

 cealing piece of sponge, held securely 

 bv the highly modified last t\vo pairs of 

 legs. (France. Ralph Buchsbaum) 



104. The large hermit crab of the American Atlantic coast is Pagttrtis pollicarU, com- 

 mon from Maine to Florida. This one has its soft abdomen securely protected by the 

 heavy shell of a whelk, Busijcon, a carnivorous marine snail. (Marineland, Florida) 



102. The robber crab. Birgus latro, of islands in 

 the South Pacific is able to climb coconut trees 

 and knock down the husk, wliich it then opens 

 with its large pincers to get at the meat inside. 

 (Bora Bora. Jerome and Dorothy Schweitzer)
