When the strength of the poison is compared among various spider species in terms of the lethal dose for 50% of test animals (LD 50 ), differences of 2 to 3 orders of magnitude are found (Friedel and Nentwig 1989; Nentwig et al. 1992). The same applies to the lower, and presumably more biologically relevant, dose that causes immobilization of the insect (ID 50 ).

The idea had already been formulated at the beginning of this century, when in particular Jakob von Uexkiill (1909, 1920) emphatically pointed out both the subjectivity and the predetermined nature of the relations between an organism and its environment. He regarded the things in the environment as carriers of meanings, which play quite specific roles in animals' lives. Accordingly, von Uexkiill ascribed considerable importance to their subjective experience, at a time when animals were considered more as 36 reflex machines and there was not much room in biology for the older ideas of Immanuel Kant about subjective time and subjective space.
