Hermit crabs perceive the extent of their virtual bodies
A flexible body image is required by animals if they are to adapt to body changes and move effectively within a structurally complex environment. Here, we show that terrestrial hermit crabs, Coenobita rugosus, which frequently change shells, can modify walking behaviour, dependent on the shape of the shell. Hermit crabs walked along a corridor that had alternating left and right corners; if it ...
متن کاملHermit crabs
Researchers had been divided over whether the sound was vocal or not, but the latest study, published online in the Royal Society Proceedings B shows unequivocally that the tail feathers were the source of the sound. When the researchers cut back the tail feathers — which grow back in five weeks and do not affect the birds ability to fly — the males were unable to make the noise. Tests in wind ...
متن کاملOn hermit crabs and humans.
Flynn, Laland, Kendal and Kendal’s article (this issue) plays a valuable role in two ways. First, it demonstrates how developmental psychology can learn lessons from the latest research on developmental niche construction within evolutionary biology. Secondly, for those psychologists whose main focus is the cognitive mechanisms by which humans develop their particular suite of abilities, it is ...
متن کاملShell Exchange in Hawaiian Hermit Crabs
Shell exchange behavior of intertidal Hawaiian hermit crabs was observed in the laboratory. Outcomes of 255 shell-related interactions were analyzed to test the predictive powers of two models of resource exchange . In the case of intraspecific interactions, the negotiations model (which predicts that exchanges should occur only when both crabs will gain in shell value) was superior to an aggre...
متن کاملHermit crabs and their symbionts: Reactions to artificially induced anoxia on a sublittoral sediment bottom
Hermit crabs play an important role in the Northern Adriatic Sea due to their abundance, wide range of symbionts, and function in structuring the benthic community. Small-scale (0.25 m(2)) hypoxia and anoxia were experimentally generated on a sublittoral soft bottom in 24 m depth in the Gulf of Trieste. This approach successfully simulates the seasonal low dissolved oxygen (DO) events here and ...
