Finding Dory is an ocean lover's dream come true. A whole movie about the sea? Sign us up! But, despite the movie's four-year production period and the research the animation team put into getting everything juuuust right, the film did get some things wrong.
There's one major mistake in "Finding Dory" that stands out above the rest.
Destiny, the whale shark, speaks "whale" and even taught "whale" to Dory. It's one of the major plot points of the movie. The pair grew up using whale sounds to communicate through the pipes of their aquarium home.
The only problem? Whale sharks aren't actually whales. They're sharks.
So, Destiny wouldn't have been able to teach Dory her signature bellowing whale noises.
Sharks don't communicate verbally at all. According to PBS, they lack the organs that allow other animals to make sounds.
Besides this, much of the rest of the movie (and its prequel, "Finding Nemo") are spot on. Even the more unbelievable parts of "Finding Dory" are actually real. In the movie, Hank the octopus frequently escapes from his tank and just wanders around the research institute.
Seems fishy, but there have been several proven examples of real octopus escape attempts in aquariums around the world.
Even though Destiny doesn't seem to know she's a shark, she's very aware of what all the other animals at the aquarium are. At one point, she reminds her tank mate that he is a beluga whale. She even knows that he can use echolocation to identify objects around him.
Whale sharks are pretty fascinating in their own right, even if they can't speak whale. Despite being the largest fish in the sea, whale sharks are "docile" creatures. They have huge mouths, but fill them with only plankton and small fish.
So, humans have nothing to fear if they go swimming with them.
The whale shark's size and diet is how it got its name. It eats and acts more like humpback and blue whales than the traditional great white sharks we know.
As for why "Finding Dory" chose to have their shark speak whale? We may never really know. But, it is just supposed to be a fun movie, not a documentary.
(Pretty sure octopi also can't drive cars like Hank does at one point.) So, we won't go too hard on them.
After all, a whole movie about the ocean is certainly nothing to complain about.
