While Disney/Pixar has produced a wonderful story with “Finding Dory” they have made some rather large mistakes in marine biology and Jonathan is here to discuss his top 3.
1. Destiny is a whale shark, not a whale. How can a whale shark speak whale? Can a Tiger shark speak Tiger?
2. A Beluga‘s echolocation doesn’t work in air and certainly can’t see what is inside a truck on the other side of a mountain.
3. Marine fish (i.e. salt water fish) cannot live in fresh water!
