Scientists in Monterey Bay were surprised to discover that an underwater robot they had deployed recently to study harmful algae blooms had been attacked by a great white shark.
The underwater robot is named Tethys, which was used in the Monterey Bay Aquarium Research Institute's CANON experiment: a two-week project that tracked nutrients that fertilize algal blooms off Central California.
Apparently, a large great white shark mistook the long-range autonomous underwater vehicle (LR-AUV) as prey.
The top photo shows technician Thomas Hoover measuring bite marks left by what scientists believe is a 12- to 15-foot white shark.
The second photo shows Jim Bellingham displaying a tooth that was embedded in the robot.
"The aluminum shell and carbon-fiber fairing of the vehicle were badly scratched, but held up to the crushing bite–a testament to the design skills of MBARI's engineers," MBARI stated on its website.
