A bunch of these guys once protected me from a Megalodon and a Manta by swarming all around me to prevent my death...

I tamed one of these named Diana. She was super fast but kind of stupid: always getting stuck on something. Diana and I formed somewhat of a relationship as time went on. Our bond strengthened she was able to beach a shark for me to kill it. Diana soon became one of my best friends... but nothing lasts forever. As I was leading her back to base via SS Dodo, I noticed a large figure swimming rapidly towards us. Diana made the fatal mistake of not paying attention to her surroundings. I helplessly fire arrow after arrow at it, but it was so filled with rage that they had no affect. I had to watch as MY Diana was ripped to shreds by an oversized fish. That is why my base is now called Fort Diana in honor of the brave soul. Thank you for your time.

Tame it at herbivore island, there is a circle in the middle of the island where there are alot of them and they are trapped so it is easy to tame

The swimming pancakes named manta and the fanged fish named megalodon and piranha don't like people trying to tame this guy. Just wanted to warn ya.
