They are not like Dolphins to have fun and be a playmate. But researchers say crocodiles are just like us and they wish to surf waves, play ball and go on piggyback rides.
Crocodiles have been studied in all three main types of play distinguished by behaviour specialists: locomotor play, play with objects and social play, said Vladimir Dinets, psychology professor at the University of Tennessee, Knoxville.
Dinets, who has been studying crocodiles for over a decade, conducted an informal survey of crocodilian-themed groups on social media and during the conferences. He observed a juvenile alligator playing with a river otter too.
In some rare cases, individual crocodilians have been known to bond so strongly with people that they become playmates for years, Dinets pointed out giving an example too.
A man who rescued a crocodile that had been shot in the head became close friends with the animal and they played every day until the crocodile’s death 20 years later, he said.
“The croccodile would swim with his human friend, try to startle him by suddenly pretending to attack him or by sneaking up on him from behind, and accept being caressed, hugged, rotated in the water and kissed on the snout,” Dinets explained.
Crocodilians have been spotted playing with wooden balls, noisy ceramic bits, streams of water, and debris floating in the water.
Cases of locomotor play include young alligators repeatedly sliding down slopes, crocodiles surfing ocean waves and caimans riding currents of water in their pools.
In other cases, researchers observed baby alligators riding on their older friends’ backs, baby caimans playfully “courting” each other and a male crocodile giving his lifetime mate rides on his back.
The study has been published in the journal Animal Behavior and Cognition.
