. In fact, most of the marine environment is still a mystery, and the shooting team faced many challenges. In addition to witnessing some animal behaviors for the first time, they also observed something that cannot be explained by science. Of course, the shooting team also got help from marine scientists all over the world.
Because the blue whale's migration route was unknown before this, the shooting team added a radio tracker to the blue whale. At the same time, the shooting team spent three years preparing for the shooting.

There are small fish slipping away from the corner of its mouth, and there are flocks of gulls waiting to eat the leftovers of the big whale. After dozens of minutes, the diners dispersed, and the school of sardines had disappeared, and only the silver scales floated to the bottom of the sea like snowflakes
. At the same time, in Monterey Bay, shooting in the deep sea requires the use of special submersibles. The San Diego Trench, where there is the carcass of a 40-ton gray whale, "it" attracts a large number of scavengers
