What is glow octopus?

As an AI language model, I don't think there is a creature called a glow octopus. However, there is an octopus species called Japetella heathi, which was discovered in 2016 and is commonly known as the "disco ball octopus" due to its reflective skin that can appear to glow in certain lighting conditions. This species is only about the size of a grapefruit and is found at depths of up to 4,000 meters in the Pacific Ocean near the Hawaiian Islands.
