Insect-Like Olfactory Adaptations in the Terrestrial Giant Robber Crab
The robber crab (Birgus latro), also known as the coconut crab, is the world's largest land-living arthropod, with a weight reaching 4 kg and a length of over half a meter. Apart from the marine larval stage, this crab is fully terrestrial, and will actually drown if submerged in water. A transition from sea to land raises dramatically new demands on the sensory equipment of an animal. In olfac...
متن کاملAggression and Food Resource Competition between Sympatric Hermit Crab Species
The vertical zonation patterns of intertidal organisms have been topics of interest to marine ecologists for many years, with interspecific food competition being implicated as a contributing factor to intertidal community organization. In this study, we used behavioral bioassays to examine the potential roles that interspecific aggression and food competition have on the structuring of interti...
متن کاملOntogeny of shell-related behaviors and transition to land in the terrestrial hermit crab Coenobita compressus
The marine megalopa of the terrestrial hermit crab Coenobita compressus wears a small gastropod shell that it carries onto land before metamorphosing into a juvenile crab. This paper gives the first detailed account of temporal shifts in shell-related behaviors that occur as the megalopa approaches metamorphosis. Megalopae placed in individual containers shortly after metamorphosing from the la...
متن کاملBehavioral evidence illuminating the visual abilities of the terrestrial Caribbean hermit crab Coenobita clypeatus.
Hermit crabs hide into shells when confronted with potential dangers, including images presented on a monitor. We do not know, however, what hermit crabs can see and how they perceive different objects. We examined the hiding response of the Caribbean hermit crab (Coenobita clypeatus) to various stimuli presented on a monitor in seven experiments to explore whether crabs could discriminate diff...
متن کاملTransition from sea to land: olfactory function and constraints in the terrestrial hermit crab Coenobita clypeatus
The ability to identify chemical cues in the environment is essential to most animals. Apart from marine larval stages, anomuran land hermit crabs (Coenobita) have evolved different degrees of terrestriality, and thus represent an excellent opportunity to investigate adaptations of the olfactory system needed for a successful transition from aquatic to terrestrial life. Although superb processi...
