Amphitrite is beautiful, with flowing black hair and little horns like crab claws. She wears green armor. Her little crab Horns maybe an inheritance from her Father, Oceanus.
Amphitrite is a formal sea goddess, calling her husband 'my lord'. She seems hurt by her husbands' liasons, and probably wasn't happy when Poseidon promised on the River Styx that he wouldn't have anymore demigod children, but it was not kept. In myths though, she is not jealous of her husband's affairs with mortal women, but doesn't approve of it either.
