In the last few months we’ve been very lucky and have had an extraordinary number of coconut octopuses (Amphioctopus marginatus) on dives in Lembeh. These intelligent critters are the only mollusk known to use tools, and everyone who sees them agrees they have the most fascinating behaviour! Other awesome sightings included harlequin shrimp, hairy frogfishes galore and the rare magnificent shrimp goby with its sail-like dorsal fin and dapper red-and-white partner shrimp. We hope you enjoy the video as much as we do!
