So they are similar to whales as in they breach, but no one really knows why!
Hi!  Do you know anything about manta rays? I know they are found in warm temperature such as subtropical and tropical water! They are pretty amazing creatures.  You can swim with them as they are quite docile. Yes, they are also large rays that belong to the "Manta" genus. Wow!  do you know any other cool facts about them?  I didn't know their genus!
Like whales, they breach, for unknown reasons.
