Fukurokuju is usually portrayed as bald with long whiskers and an elongated forehead. He is said to be an incarnation of the Southern Polestar. The sacred book tied to his staff either contains the lifespan of every person on earth or a magical scripture. He is accompanied by a crane and a turtle, which are considered to be symbols of longevity. He is also sometimes accompanied by a black deer (ancient legends say a deer turns black if it is over 2000 years old).
He is the only member of the Seven Lucky Gods credited with the ability to revive the dead. (From Wikipedia)
