Breaching is an energetically expensive behavior which depends on a number of interconnected elements. The length of the animal is one of the most limiting factors, affecting, for instance, body maneuverability. Shorter whales require lower swimming speeds to breach, and therefore lower muscle power. The surface area of flukes and flippers also influences how fast a whale can swim and turn. These and other features determine whether the animal has the capacity to expend a large amount of energy in a very short time (high energetic performance), and is therefore able to breach.
