I'm liking this new series Hive account@mountainwashere. I love posts that teach me something new as a biologist. The idea of multiple umwelts is certainly an interesting one, particularly in cases of creatures which theoretically can't integrate the different inputs into one, cohesive 'vision' (as we would see it). The really interesting question is whether this then generates a cognitive barrier to developing higher intelligence as the functioning of these types of animals is far more like an automaton (in the same sense that insects are - functioning largely on a set of stimulus-response functions). Thought provoking stuff!
