Aliens of the deep

When inspecting deep water moorings for fish farming in a Norwegian fjord, we encountered a meeting with the alien of the deep, Periphylla periphylla. Like vampires and trolls of ancient tales, if they see the sun rise, they will die. Like many of the deep-water creatures, Periphylla has developed bioluminescence and is enable to change colours; it is almost pulsation with light. For more information about the Periphylla:, by Christian Skauge Stinger has developed special tooling and operational procedures for this 330 meters deep water mooring inspection, using the micro ROV Pro4 from Videoray.
