A remotely operated vehicle was used to collect the hatchelling’s egg form the coral reef.
This was about 2 000 meters below the ocean surface.
They live just above the seafloor. Some have been seen as deep as the 7 000 metres.

People from the Aquarium of the Pacific, have seen them that deep.
According to a video they are also very good dancers. It appears that this octopus has enough food in its stomach to keep it alive until they learn to catch their own food.
I just put a picture of the egg that they fetched and a picture of the baby elephant octopus in here as they are so beautiful.
All this is available from live science, it is so wonderful how fantastic nature can be.
