Thalassa

[5] According to a scholion on Apollonius of Rhodes, the fifth-century BC poet Ion of Chios had Thalassa as the mother of Aegaeon (Briareus, one of the Hecatoncheires).

[9] The Roman mythographer Hyginus (c. 64 BC – AD 17), in the preface to his Fabulae, calls Mare (Sea, another name for Thalassa)[10] the daughter of Aether and Dies (Day), and thus the sister of Terra (Earth) and Caelus (Sky).

"[14] In yet another fable, Perry's number 412 and only recorded by Syntipas, the rivers complain to the sea that their sweet water is turned undrinkably salty by contact with her.

[15] In the 2nd century CE, Lucian represented Thalassa in a comic dialogue with Xanthus, the god of the River Scamander, who had been attacked by a rival Greek deity for complaining that his course was being choked with dead bodies during the Trojan War.

There she was depicted as a woman clothed in bands of seaweed and half submerged in the sea, with the crab-claw horns that were formerly an attribute of Oceanus now transferred to her head.
