Pagina 155 - Then turning round its body, by the aid of its posterior and narrow pair of pincers, it extracts the white albuminous substance. I think this is as curious a case of instinct as ever I heard of, and likewise of adaptation in structure between two objects apparently so remote from each other in the scheme of nature, as a crab and a cocoa-nut tree.
Pagina 154 - Liesk assures me that he has repeatedly seen this effected. The crab begins by tearing the husk, fibre by fibre, and always from that end under which the three eye-holes are situated ; when this is completed, the crab commences hammering with its heavy claws on one of the eye-holes till an opening is made.
Pagina 81 - ... a perfect shell like the former ; it is however remarkable that during this change there are some stony concretions always formed in the bag, which waste and dissolve gradually as the creature forms and perfects its new crust.
Pagina 155 - ... yields as much as a quart bottle full of limpid oil. It has been stated by some authors that the Birgos crawls up the cocoa-nut trees for the purpose of stealing the nuts: I very much doubt the possibility of this; but with the Pandanus* the task would be very much easier. I was told by Mr. Liesk that on these islands the Birgos lives only on the nuts which have fallen to the ground.
Pagina 81 - ... he gets rid of his old shell and is fully provided with a new one. How long they continue in this state is uncertain, but the shell is observed to burst both at the back and sides to give a passage to the body, and it extracts its limbs from all the other parts gradually afterward.
Pagina 81 - August the crabs fatten again and prepare for mouldering, filling up their burrows with dry grass, leaves, and abundance of other materials : when the proper period comes each retires to his hole, shuts up the passage, and remains quite inactive until he gets rid of his old shell and is fully provided with a new one.
Pagina 281 - ... spines, which shut into corresponding sockets, arranged in a groove in the next joint, which also bears smaller spines. By means of this singular organ they can hold their prey securely, and can give a severe wound to the human hand, if handled incautiously. It also uses the stout caudal appendages, which are armed with spines, very effectively. The colors of this species are quite vivid, considering its mud-dwelling habits. The body is usually pale green or yellowish green, each segment bordered...
Pagina 154 - The front pair of legs terminate in very strong and heavy pincers, and the last pair are fitted with others weaker and much narrower. It would at first be thought quite impossible for a crab to open a strong cocoa-nut covered with the husk, but Mr. Liesk assures me...
Pagina 355 - Hay, in recently observing the habits of ScyphaccUa arenicola. finds that it also burrows in the sand. The Serolidie, according to Studer, " live by preference on sandy ground, into which they burrow with their flat bodies up to the caudal plate." Whitelegge speaks of the paguroid habits of certain Isopods, which "live in small univalve shells and in company with young hermit crabs.
Pagina 141 - ... five most minute cups are placed which seem to act in the same manner as the suckers on the arms of the cuttle-fish. As the animal lives in the open sea, and probably wants a place of rest, I suppose this beautiful and most anomalous structure is adapted to take hold of floating marine animals.
