Remotely operated vehicle (ROV) technologies dive into the deeper blue, giving us the chance to get up close with the amazing flora and fauna that inhabit our seas.

Your challenge: Analyse a video from ROV specialist, GeoOceans, monitoring sites at Point Lowly then perform some calculations to quantify the cuttlefish density.

To take the challenge, read about the Giant Australian Cuttlefish, follow the challenge instructions, and watch the video to complete them.
