Water droplets live in the deep sea near Australia and Tasmania. Because droplets live in remote areas, humans rarely see them. The water pressure in the place where the drop fish lives is dozens of times that of sea level. In this environment, it is difficult for fish fat to work effectively.
In order to maintain buoyancy, the water drop fish’s body is made of a gelatinous substance that is slightly less dense than water. This allows the drop fish to float easily from the bottom of the sea without effort. Lack of muscle is not a big problem for the water drop fish, because it mainly depends on the plankton in front of it for its livelihood.
