Palaemon is the god of sharks and the patron of harbors.
Palaemon was a sea divinity and the tutelary god of ports and shores. Under the name Melicertes he had been a child of Ino and Athmas. Ino had nursed the god Dionysus, one of Zeus' many illegitimate children, and the jealous Hera had driven Athmas mad, so that he pursued his wife with intent to kill her. Carrying her child, she leaped into the sea, where both of them became minor deities-he thereafter called Palaemon and she Leucothea. He was usually portrayed riding on a dolphin and was invoked as a savior from shipwreck. The Isthman Games were celebrated in his honor.
