Survival behaviours

Yabby at Sydney Aquarium

The yabbies in our school aquarium make suitable subjects for a study of animal behaviour. Can you classify yabby behaviour according the following:

  • feeding
  • maintenance
  • territorial
  • agressive
  • defensive
  • co-operative
  • reproductive
  • parenting

Which are learned behaviours and which are innate? How are each of these behaviours important to the survival of the yabby as a species? How do you think the behaviour of the yabby is modified by being confined to an aquarium? Can you observe yabbies communicating with each other?
