10 Animals With Surprisingly Complicated Love Lives
7. The Ritualistic Courtship of Japanese Pufferfish

In the coastal waters of Japan, male pufferfish engage in one of the most elaborate courtship rituals in the marine world. Male pufferfish meticulously construct intricate sand patterns on the ocean floor to attract a mate, creating geometric designs that can reach up to six feet in diameter. These patterns, known as "mystery circles," serve as visual displays to entice females. The construction of these circles requires precision and patience, as the male uses his fins to carve ridges and grooves in the sand. Once a female is attracted to a circle, she inspects the design before deciding to mate with the artist. The complexity and beauty of these underwater artworks highlight the role of creativity and craftsmanship in animal courtship.
