Megamouth shark Parks and Wildlife, opened to the public since March 3, 2015, which coincided with Albay's celebration of the World Wildlife Day. The megamouth shark was preserved through taxidermy, and is now considered one of the more precious collections of Albay, a leading province in environment protection. On April 14, 2016, a deceased megamouth shark was caught in a fisherman's net in Japan's Mie Prefecture, around three miles off Owase Port. The shark weighed an estimated . In August 2016 the shark was dissected before an audience of students and academics. The event was organized by Osaka Aquarium in Osaka, Japan.
Robot fish instead of forward swimming only. The shapes and sizes of fins vary drastically in living fish, but they all help to accomplish a high level of propulsion through the water. In order for robot fish to achieve the same type of rapid and maneuverable propulsion, robot fish need multiple control surfaces. The propulsive performance is related to the position, mobility, and hydrodynamic characteristics of the control surfaces. The key to controlling a multi-joint robotic fish is creating a simplified mechanism that is able to generate a reasonable amount of control. Designers should consider some important factors, including lateral body motions,
