Go little bot go! A self-navigating robo-sea-snake sounds terrifying but I think this guy is actually pretty cool, and his purpose is even cooler!

Yep this little autonomous guy has a combination of mechanical but also BIO SENSORS. These bio censors are made up of bacteria, crustacean and fish cells that are GROWN directly on the sensors that tell it if there's something toxic in the water so it can autonomously navigate to its source and alert us humans so we can take care of it.

I didn't even know we could grow fish cells on censors... much less the rest of the stuff this little guy can do! Also, I think he's kinda cute!
