Sailen Majhi was hunting crabs along with three others at a creek since August 25.
When they were pushing their boat to a river to leave the creek and return home last evening, a tiger pounced on him and dragged him away, the officials said.
The other three tried hard to chase the predator but failed, the officials said, adding the body was not yet found.
Majhi was a resident of Jharkhali under Basanti police station.
