Big Blue Octopus Octopus cyanea  occurs in the tropical Indo-Pacific from eastern Africa to the Hawaiian Islands in a depth range from 0-150m, max. mantle length 22cm with arms to at least 80 cm. \nBig blue octopuses are found living in muddy, sandy, or rocky bottoms, and in seagrass beds. They create lairs or dens in crevices or coral rubbles within coral reefs. These dens aren't used for long term; on average individuals spend up to 35 days in one den. The average lifespan of big blue octopuses is 12 to 15 months.\nThis juvenile specimen was encountered in the Triton Bay, Indonesia \n3°54'41.052 S 134°7'18.204 E at 12m depth
