A closer look

Starfish operate entirely on vibes and a decentralized nervous system. They possess no central brain whatsoever, instead relying on a network of nerves spread throughout their arms to sense the environment and hunt prey. Furthermore, they don't even have blood. Instead, they use a water vascular system, pumping filtered seawater through their bodies to deliver nutrients and power their thousands of tiny tube feet. It’s an evolutionary masterclass in biological outsourcing.
