The orca is one of earths most wide ranging animals, found all over the globe but especially in food-rich areas. They swim to 150km and can dive to great depths. A wild orca spends its entire life in the ocean, resting and sleeping in the water. They can swim up to beaches to grab sea lions, and use 'rubbing beaches', rubbing their bodies along smooth pebbles. Rubbing is obviously a pleasurable social activity.
Orcas can hunt co-operatively, top the marine food chain and have no predators.
Adaptations Orca bodies are modified to cope with life as a sea predator. Behaviour Sound travels well in water and orcas communicate with calls, clicks and whistles. They use 'echo-location' clicks to navigate and find food. Orcas can leap out of the water to 'breach'. Orcas also 'spy-hop', rising vertically in the water with their heads in the air, looking around.
