2025 Annual Report
A silver metal robotic arm holds a camera to film a deep-sea octopus crawling over the rocky deep seafloor. The camera has a silver metal housing with a black plastic cap and five red lights. The camera is on the left side of the frame, filming an octopus on the right side of the frame. The octopus has a bulbous pale purple body and eight arms. In the foreground is rocky seafloor covered in fine brown sediment. In the background is black water, with several fan-like corals on the horizon.

MBARI researchers deploy new technology to study deep-sea octopus movement

MBARI engineers are creating innovative technologies to visualize marine life in exciting new ways. The EyeRIS camera system—developed by MBARI’s Bioinspiration Lab with support from the Gordon and Betty Moore Foundation—collects near real-time three-dimensional visual data about the structure and biomechanics of ocean animals with a single camera and lens.

MBARI researchers used EyeRIS to observe deep-sea pearl octopus (Muusoctopus robustus), tracking the movements of specific points on an octopus’s arm. They found that pearl octopus use temporary muscular joints that yield simple, but sophisticated, control of their arms while crawling over the rugged seafloor.

EyeRIS is a game-changer for studying the biomechanics of marine animals in their natural environments, providing important insights that can open the door to designing exciting new bioinspired technologies in the future.
