What are some examples of biomimetic robots inspired by marine organisms, and how do they replicate features such as propulsion, hydrodynamics, and sensing mechanisms to mimic underwater creatures such as fish, jellyfish, or octopuses?

Examples include underwater robots, underwater gliders, and soft robots designed for marine exploration, oceanography, and underwater surveillance. Biomimetic robots use fins, flippers, or tentacles for propulsion and maneuvering, as well as hydrodynamic shapes and sensors for navigation, obstacle avoidance, and environmental monitoring in aquatic environments.
