Amphitrite both the Nereids "and" the Oceanids. Others called her the personification of the sea itself (saltwater). Amphitrite's offspring included seals and dolphins. Poseidon and Amphitrite had a son, Triton who was a merman, and a daughter, Rhodos (if this Rhodos was not actually fathered by Poseidon on Halia or was not the daughter of Asopus as others claim). "Bibliotheca" (3.15.4) also mentions a daughter of Poseidon and Amphitrite named Benthesikyme. Amphitrite is not fully personified in the Homeric epics: "out on the open sea, in Amphitrite's breakers" ("Odyssey" iii.101), "moaning Amphitrite" nourishes fishes "in numbers past all counting" ("Odyssey" xii.119).

This myth is construed by Robert Graves and others as reflecting a clash between the inhabitants during Mycenaean times and newer immigrants. Athens at its height was a significant sea power, at one point defeating the Persian fleet at Salamis Island in a sea battle. Poseidon and Apollo,
