In 2013, the marine researchers deployed REMUS in the waters near Guadalupe Island to track sharks and film them interacting with their environment. Some sharks became territorial, charging REMUS and bumping it aggressively. Other sharks behaved in a more predatory manner, lurking in the depths below REMUS and then swimming up quickly to bite the robot. This is the same technique used to hunt seals.
To the delight of the researchers, the SharkCam survived dozens of interactions captured not only in the video but also in the teeth marks left behind in the hull of the robot. One researcher can be heard saying, "We lost our deposit," as REMUS is pulled from the water.

According to WHOI, "Plans are currently underway to use the system to follow other large marine animals such as sea turtles."
