A high-tech SharkCam invented by a Cape Cod researcher offers an unprecedented window into the lives of the ocean’s toothy predators, and can also extend to seals, whales, turtles and squid for a big-picture view of precious ecosystems and how to protect them. “These vehicles, these underwater robots that look like highly complex systems are just an extension of yourself to be able go where people can’t go, and there’s no limitation to what they can do,” said Amy Kukulya, research engineer and principal investigator at Woods Hole Oceanographic Institution.
