What is the name of Crush's son?

Crush’s son is named Squirt.

Squirt appears with his father, Crush, among the sea turtles riding the East Australian Current in Finding Nemo (2003). After Marlin and Dory are stunned by jellyfish, the turtles help carry them along the current toward Australia. Squirt is energetic and adventurous, reflecting the easygoing attitude that Crush encourages in Marlin.

Crush’s parenting style contrasts sharply with Marlin’s overprotectiveness. Crush allows Squirt to experience the current and learn through action, while Marlin worries constantly about Nemo’s safety. Watching the turtles helps Marlin understand that protecting a child also means allowing independence.

Squirt returns in Finding Dory, where he is again identified as Crush’s son. Nicholas Bird voiced him in Finding Nemo; Bennett Dammann voiced the character in Finding Dory. Squirt is sometimes confused with Nemo because both are young sea characters who join the story’s journey, but Nemo is Marlin’s clownfish son, while Squirt is the juvenile sea turtle traveling with Crush.
