Megamouth shark following day. As of July 2017, the preserved and partially dissected head of a megamouth shark was on display at Osaka Aquarium in Osaka, Japan. On July 25, 2017, a megamouth shark was recorded on video at Gili Lawa Laut near Komodo island, Indonesia, as it swam slowly past divers Penny Bielich and Heikki Innanen. The shark appeared to have at least one remora attached. On February 11, 2018, a juvenile male measuring 4.34 meters in length was accidentally entangled in a fishing net off the coast of Negros Oriental in the Philippines. The body of the deceased shark was
Robot fish kinematic data and anatomical data. When designers mimic a BCF-type robot fish, the link-based body wave of the robot fish must provide motions similar to that of a living fish. This kind of body wave-based swimming control should be discrete and parameterized for a specific swimming gait. Ensuring swimming stability gait can be difficult, and transitioning smoothly between two different gaits can be tricky in robot fish. A central neural system known as a "Central Pattern Generator" (CPGs) can govern multilink robotic fish locomotion. The CPG is located in every segment, and can connect and stimulate contracting or stretching muscles.
