A robotic dolphin with a sleek, streamlined body covered in smooth, waterproof silicone. The body is light gray on top and fades to white on the underside. It has a rounded forehead (melon) with built-in sensors and lifelike, glossy black eyes. The mouth is slightly curved with visible artificial teeth. The pectoral fins are flexible, while the dorsal fin is semi-rigid. The tail fluke moves up and down for propulsion. The surface has a wet sheen, and subtle LED accents emit a soft blue glow.
