“…Many shell features are highly correlated with each other (52) and with crab size; thus experimental or statistical dissections are necessary. Shell weight has been suggested as the parameter affecting crab choice the most in some cases (82), while shell internal volume has been suggested by other work (115). If one shell characteristic is of primary importance, it may change depending upon the relative size of the currently occupied shell-weight being more important if the shell is too big, volume if it is too small (36).…”

“…However, supralittoral (semi-terrestrial) hermit crabs, by their nature, have very different behaviour, access to resources and face very different predation and physiological pressures (Burggren & McMahon 1988). Yet, to date, little more is known of shell use by tropical supralittoral species than the preliminary work of Volker (1967) on Coenobita scalveola.…”

The use of gastropod shells by hermit crabs at Quirimba Island, Mozambique, was investigated. Particular attention was paid to the upper shore/supralittoral zone species Clibananus longitarsus, Coenobita cavipes and Coenobjta rugosus. The study area is characterised by a high diversity of gastropod species as well as hermit crabs. Supralittoral hermit crabs were little, if at all, resource restricted due to concentration of empty shells on the strandline and shell rniddens created by local people. The range of the 3 study species overlaps substantially and each uses a wide range of shell types. Shore habitat, shell abundance and availability were found to have little influence on shell use. With increased tidal emersion/terrestrial nature (for a given crab mass), total diversity of shells used increased, shell mass carried decreased, damaged shell use decreased and carried shell fit increased. The architecture and strength of shells used, however, followed more complex individual species characteristics and behaviour patterns. Species specific differences in behavioural patterns may be important for shell resource partitioning.

“…They fill their shells with sea water and feed on Sargassum weeds (Magnus 1960, Niegerman 1968. Volker (1967) studied shell selection behavior of C. scaevola in El-Ghardaqa and showed that the most common shells used were those of Turbo and Galeodes, the most common gastropods in the area. Volker (1969) also studied the morphology of the chelae and pleopods which make u p the 'operculum' of the shell inhabited by C, scaevola.…”

Coenobita scaevola (Forskal) is a terrestrial hermit crab inhabiting shores of the S~n a i Peninsula, where animals encounter severe conditions of high temperature, high radiation and low relative humidity. Adaptation of these crabs to such arid conditions was studied. The crabs are nocturnally active, taking refuge during the day in hiding places with milder conditions. Body temperature follows that of their hiding places, which is lower than that of the air. After ca 6 h exposure to direct radiation, the crabs die. Thermoregulatory abil~ty is low. Water loss is lower In shelled crabs, higher in crabs without shell; the shell protects the abdomen from desiccation. Freshly killed crabs evaporate less than live crabs, suggesting that evaporation from live crabs is not a purely passive process. Gill surface area is small in comparison with aquatic crabs. Aquatic oxygen consumption is 1.4 times higher than aerial. Unlike other Coenobita spp. which inhabit sites distant from the sea, and in spite of successful adaptation to terrestrial life, Coenobita scaevola does not penetrate far inland: In desert conditions it depends on the sea for its only water source.
