Abstract
ALTHOUGH it is at first sight unlikely that a crab should
take note of the direction of the Sun's movement directly,
two lines of evidence already suggest this conclusion.
Crabs follow with their eyes the movements of a striped
drum which is revolved around them at speeds even lower
than one revolution per day1, and several species of lower
Crustacea2 as well as the Pacific shore crab H emigrapsus3
utilize some feature of the path of the Sun as a basis for
directional escape movements in relation to the local
direction of the sea.
