Spyhoping orca / killer whale

It is said that an orca’s eyesight is equally good in or out of the water. In fact it is thought they use eyesight when ‘spyhopping’ to spot boats that may present a danger. Orca do not seem to fear boats but once a motor is turned off and no sound is coming from the boat it becomes harder for them to locate. “Orcas possess sophisticated underwater sonar that enables them to perceive their surroundings ten times more effectively than our most advanced equipment.” (http://www.orcafree.org) However a boat’s shallow draft may make it harder to locate and thus the need for an occasional spyhop.  Great photo from James Wendy of Australia.
