Violence & Gore: 2
A barracuda with very long and pointed teeth snaps viciously at two fish, one fish is knocked unconscious, and the other fish along with many eggs are gone when he comes around (the barracuda apparently ate them although we do not see it).
A shark exposes a fish skeleton in his mouth. He is implied to have eaten the fish.
A fish is hit in the nose, her nose bleeds, a shark gets a whiff of the blood and goes into a frenzy chasing two fish through a wrecked submarine, crashing into doors, lunging through hatches, breaking through the hull and trying to squeeze into a torpedo tube; the two fish push a torpedo into his mouth, he spits it out, and it floats toward an underwater mine field setting it off.
Two fish swim into very deep and very dark water, they see a light and begin to follow it, but it turns out to be a anglerfish with very sharp teeth, and it chases them and snaps at them (one fish ends up in its stomach, along with its lighted lantern, briefly).
Two fish are surrounded by jelly fish (one is stung a couple of times), they bounce off the tops and try to get out but one is trapped; the other returns to save it and they both fall unconscious after being stung several times (one has scars on its side).
There are tense moments when a young fish goes into an aquarium filter to clog it with a pebble and is sucked back into the filter tube toward a fan -- it is pulled out just before hitting it.
A wrecked submarine slips off a reef and nearly pins two fish against a rock formation.
Two fish are sucked into a humpback whale's mouth and one rams repeatedly at its "teeth" (actually baleen plates used to filter krill and plankton) trying to get out. Eventually, water rushes through, the two trapped fish cling to the whale's tongue, and they are shot out of its blowhole.
A large fishing net scoops many fish into it, they scream and panic, but then they swim hard downward and the net breaks and the fish are freed -- one fish seems injured but it's fine.

Two fish flap around on a pier surrounded by seagulls, and one is picked up and pulled on by the seagulls.
A pelican scoops the two fish up and flies off, is chased by many seagulls, they swoop and fly and end up slamming into a boat's sails (their beaks poke through).
A large shark smiles and laughs menacingly at two fish showing his many rows of pointed teeth, he escorts them to a meeting with two other sharks and the fish are frightened that they will be eaten.
A frightened fish swims erratically in a tank and runs into the glass a few times, and a pelican flies into a window a few times.
Two fish approach an eerie trench with fish bones in it.
A pelican swallows two fish, but they fight back and he has to eject them.

A fish gets stuck in a tube, two fish steal a crab's shell to tease it, and a baby fish bounces off a sponge and lands on the sea floor crying.
A scary looking anglerfish chases Marlin and Dory and tries to eat them up. If you stay during the end credits, there is a scene where a small nervous fish eats the anglerfish up.
