The underwater world on display in Disney’s “Finding Nemo” is teeming with a dizzying array of cheery creatures, from sea turtles to seahorses and mackerel to sharks. So a team of Canadian and U.S. scientists decided to assess the mythical ecosystem inhabited by the small clownfish and his friends to see how their real-world counterparts were faring.
It turns out that when it comes to surviving in a non-Pixar sea, being adorable isn’t enough.
Sixteen percent of the species associated with characters in “Finding Nemo” that have been evaluated face the threat of extinction, according to the study, which was conducted by the International Union for Conservation of Nature (IUCN) and Canada’s Simon Fraser University. The analysis of 1,568 species is not just a whimsical look at American popular culture and its cartoon characters. It reveals how humans treat some of the ocean’s most charismatic inhabitants.
“These are species that should be doing better because they are the ones we care about,” said Loren McClenachan, a post-doctoral fellow at Simon Fraser University. She said that highly migratory species such as turtles, sharks and rays are particularly vulnerable to fisheries and other human pressures. “They’ve got life histories that cause them to interact with people wherever they go,” McClenachan said
