Suction cup tags, like this CATs tag (https://cats.is) are non-invasive devices with built-in cameras, pressure sensors, accelerometers, gps, and other measuring tools. Data collected by these tags make it possible to better understand the behaviors of marine megafauna, such as humpback whales, dolphins, orcas, and sharks. The more we understand the positive and negative impacts to marine habitats, the better we are able to protect and safely share the critically important ecosystems with all species on earth.
