Because of the busy work recently, I haven t moved the video for two months. Let s give a warning first.

Because I’ve been busy recently and haven’t moved video for two months, let’s start with a warning. I got permission from Yuriy Smityuk, a Russian photographer’s younger brother, to reproduce a video recording the tail sail of a large-winged whale. Because the chat is all based on translation software, and some place names are not translated, so I need to send it later.
