Amphitrite was one of the fifty Nereides(sea goddesses). To the Romans, she was Salacia. Her parents are either Oceanus and Tethys or Nereus and Doris. She, along with the other Nereides, were known to help sailors in need.

From the moment Poseidon saw Amphitrite, he knew that he wanted to marry her. However, she was against this. In an attempt to escape his advances, she hid deep in the ocean. Poseidon was not about to let the his future bride slip through his fingers so easily. He dispatched a dolphin to find her. The dolphin, went above and beyond the call of duty and actually brought Amphitrite to Poseidon. After all this, Amphitrite agreed to marry Poseidon and they went on to have Triton as their son.
