How did thetis and amphitrite distinguish themselves?

Thetis and Amphitrite are both sea goddesses in Greek mythology, but they distinguished themselves through their roles and associations. Thetis, a daughter of the sea god Nereus, is known for her close ties to gods and heroes, particularly as the mother of Achilles and her involvement in the Trojan War. In contrast, Amphitrite, a granddaughter of the primordial sea god Oceanus, is primarily recognized as the wife of Poseidon and queen of the sea, embodying the nurturing and protective aspects of the ocean. Their distinct narratives highlight their unique contributions to the mythological landscape of ancient Greece.
