The Trench is a location in Finding Nemo.
Finding Nemo[]
It is a large, dangerous trench. A fish skeleton is seen on a rock, showing dominant fish and other creatures live in the trench. The Moonfish tell Dory to swim through the trench, not over it, but a skittish Marlin denies the Moonfish's advice and convinces Dory to swim over it when they arrive there, thinking it is safer. This proves to be a bad move, as it has a sea of Jellyfish above it.
