Why is the bullet train shaped like a armadillo?

The bullet train, particularly the Shinkansen in Japan, was inspired by the shape of an armadillo to reduce air resistance and improve aerodynamics. The armadillo's streamlined body allows it to move efficiently through its environment, which parallels the need for high-speed trains to minimize drag. This design not only enhances speed but also reduces noise, making the trains more environmentally friendly and comfortable for passengers. The creative choice reflects the integration of nature-inspired solutions in engineering.
