As I may have mentioned, I really enjoy watching a good villain. Villains always seem to have the most fun. The perfect example is Tamatoa from Disney’s Moana, who has the all the best lines and steals every scene he is in, while also having the best bad boy song ever. My only problem … as a zoologist, I looked at Tatatoa and immediately thought to myself “But most crabs moult. Wouldn’t that mean he would lose that love shiny shell every year?”
Nope. Juvenile coconut crabs do moult, and like hermit crabs, the little crabs wear scavenged shells for protection. However, as adults, they grow a tough outer integument. The coconut crab reaches sexual maturity around five years after hatching. but they reach their maximum size only after 40 to 60 years. They are fully terrestrial once they mature, and can drown if held under water for too long (hence Tamatoa living in an air bubble).
So Tamatoa could have grown to be huge, and he could be wearing a shell covered in treasure from one year to the next; even if has moulted, he could be wearing his old shell over the new one. These little details are important to me, even though giant singing crabs don’t exist. They certainly don’t have teeth!
So, why do I have to try and make sense of an animated character? Well, Tamatoa wasn’t the original form of the villain. It is obvious that the animators had done quite a bit of research of their own to come up with our glam crab. By knowing how they came up with such a charismatic antagonist might help me add a bit of that glamour to my own villains.
