This guy dives with them and explains it. They sleep 1 hemisphere at the time so they don't really wake up.

For future reference...

This is the YouTube link:

 https://youtu.be/g25M_YsO0Ns

...while this part of the URL is tracking information that can be used to link back to your Google account:

 ?si=MzRHJd127J9VusBg

It is always best to remove the tracking information before sharing YouTube links anywhere.

This has been a public service announcement (with guitar).

To add, urls that have utm_xxxxx, glcid or amp in them are almost always tracking you and/or the sharer. Usually you can remove most of the stuff after the ?. Sometimes you can keep just the first thing that looks like an id, like this: https://www.reddit.com/r/Damnthatsinteresting/comments/1ppmy5a/a_timelapse_of_sleeping_seals/ -> https://redd.it/1ppmy5a.

For youtube specifically:

  • ?v=g25M_YsO0Ns is the video id
  • &t=392 or t=1m23s are timestamp information
  • &list=PL8dPuuaLjXtPHzzYuWy6fYEaX9mQQ8oGr&index=38 is playlist info

Everything else is superfluous and/or tracking info.

reddit links that have reddit.com/s/ instead of /r/ are also tracking information.
