　　The grebes express their love with synchronized dance moves, build floating nests with flexible water plants, and even offer live fish as "betrothal gifts". They avoid the hustle and bustle and hatch the hope of life together on the water surrounded by reeds.

　　On the mudflats, there is a fish that can "walk" and even jump half a meter high. It is the mudskipper – a "rebel" that successfully escaped the ocean and made its way onto land. Its moist skin acts as a natural breathing apparatus, while its fins have evolved into limbs for traversing the muddy terrain. But the most fascinating part begins when the mating season arrives. The males inflate their gill sacs, flare their dorsal fins, and engage in a high-jumping competition, which turns out to be the ultimate key to winning a mate.
