Ugolini et al (2013) investigated the use of skylight polarisation by sandhoppers 2 8 (Talitrus saltator) (figure 4.2) captured in Italy. These very small amphipod crustaceans live on the seashore and need cues to help them to return to the damp area of sand where they live. With the movement of tides, there is a risk of dehydration if they are dry for too long, so they need to know the sea.
Precision, not classification, is the path to follow. As Ernest Rutherford said: All science is either physics or stamp collecting. To achieve precision in our description of motion, we need to select specific examples of motion and study them fully in detail. It is intuitively obvious that the most precise description is achievable for the simplest possible examples. In everyday life, this is.
Some of these earlier reports went beyond questions of identification, classification and distribution. A much stronger ecological basis and a rather different outlook has been apparent in more recent work, obviously influenced by the trends of research in other areas. The workers responsible have been able to escape very largely from the qualitative approach of the earlier works (essential.
