Whilst woodlice tend to directly respond to stimuli, for example they have positive hydrotaxis. This is a directional response, meaning that the woodlice will head to towards areas of high humidity, this is a useful survival technique given that their ideal conditions are in humidity. This taxi is completely different to preening as preening isn’t a directional response towards a stimulus but instead an act with longer term benefits. However, it could be argued that preening is not very different to a response to the stimulus of the cold.
Secondly, when incubating eggs and raising their young a pair of parent emperor penguins will alternate between going out and hunting and incubating the egg or chick, and protecting them from predators. This is another example of the increased complexity in the behaviour of Emperor Penguins compared to woodlice. This is evident as the parent incubating the chick or egg won’t...
