The
monarch that ruled the
Sea Kingdom Atlantica in the
The Little Mermaid universe. He had
seven daughters, of whom
Ariel is the youngest. She got into lots of
trouble dealing with
humans, and Triton would (unsuccessfully)
discipline her.
On a trivial note, the probability of having seven daughters in a row is 1:128. This makes Triton's menagerie of daughters a very unusual and uncommon ocurrence.
