Instead of Tranquilizers or Lethal means to deal with predators you could go another route. Researchers and television hosts (such as Dickie Chivell) have used custom seal decoys and orca dummies to study predator-prey dynamics and understand how sharks react to these shapes without relying on protective cages. It would make a lot of sense if we could outfit our vehicle chassis to give off a friendly pheremone or look like something symbiotic to the predator, like a cleaner shrimp, allowing us to get close and scan the creatures or avoid detection as we pass through their zones. Maybe a “Male” (smaller version) of the Shiver Leviathan chassis for the Tadpole would allow us to navigate past the Female. Thanks for your consideration!
