DistributionCoenobita scaevola lives around parts of the Indian Ocean, including the Gulf of Aden and the coasts of Somalia and Pakistan.[1] Although the hermit crabs of the Red Sea are poorly studied,[2] they include C. scaevola as the region's only species of terrestrial hermit crab.[1][5]TaxonomyCoenobita scaevola was first described in 1775 by Peter Forsskål,[3] under the name Cancer scaevola, with a type locality of Jeddah, Saudi Arabia.[4]Life cycleReproduction takes place during the hottest months of the year, when temperatures are {{convert|24|-|38|C|F}}.[8] In common with other hermit crabs, the young animals of Coenobita scaevola pass through a number of larval phases,[5] before reaching the glaucothoe and then the juvenile stage. C. scaevola has the greatest number of zoeal phases of any Coenobita species (seven), and they last longer than in any other Coenobita species, lasting a total of 54–80 days.[8] EcologyCoenobita scaevola can survive in arid conditions, such as those on the Sinai Peninsula, but only close to the shore, to which it must return regularly to replenish the water stored in its shell for respiration.[1][6] C. scaevola rests in burrows or among coastal vegetation during the heat of the day, and emerges at night to feed.[6] Although the air temperature outside the burrows can reach {{convert|33|C|F}} during the day, at a depth of {{convert|10|cm|abbr=on}}, the temperature does not exceed {{convert|28|C|F}}.[7]Most adults up to a carapace length of {{convert|7.5|mm|abbr=on}} occupy a Nerita undata shell. Larger individuals choose Turbo radiatus, Polinices milanstomus and Monodonta canalifera, while small individuals (below {{convert|3|mm|abbr=on|disp=or}}) occupy shells of Planaxis sulcatus and Nassarius arcularius.[8] Further reading{{Portal|Crustaceans}}{{refbegin}}
