Not all fish in the ocean are real. In Lake Zurich’s chilly waters in Switzerland, one swims with a camera to shoot underwater scenes. It also has a mission, which is to collect water samples and bring them to engineering students at ETH Zurich for analysis. The students look for traces of fish DNA to identify the kinds of fish that live in the waters. The fish called Eve is actually a robot developed by the students for the study of ocean ecosystems. Built-in pumps help it swim. The autonomous underwater vehicle also has a sonar that allows it to avoid obstacles.
