Saltwater Crocodiles enjoy catching a wave and travel hundred of kilometres by surfing on ocean currents, a study suggests. Australian researchers used sonar sensors and satellite transmitters to monitor 20 reptiles' movements. They found the crocodiles undertook numerous trips of over 10 km, but only when a current flowed in their direction of travel. The results of the research appear in the Journal of Animal Zoology.
Estuarine or saltwater crocodiles are the world's largest reptiles and can grow upto 5.5 metres length. They are poor swimmers and mainly live in salt water - but their home spans over 10000 sq km of the South-East pacific, from Sri Lanka to Fiji and from Thailand to northern Australia.
