I do not know if this video were posted already , and by respect to copyright I put the link simply (the language is here in Spanish). I translate the additional text of the video: The unit, pertaining to a species considered very rare, appeared in the Japanese coasts but it died few hours after to be filmed and to be captured. The scientists think that it was in bad conditions and he was debilitated.
Here you may see embedded video.
