海南吊罗山雨林深处，山涧溪流中，栖息着一种淡水龟，名叫平胸龟。它们处于食物链的上层，拥有硕大的头部，坚如背甲的角质层，鹰嘴状的上喙和布满四肢的利爪，可在高海拔溪流中的崖峭壁上攀爬，对猎物发起主动攻击。对于溪流中的其他生物来说，它们是致命的存在……打开视频，让我们一睹“霸主”雄风。

　　Deep in the rainforests of Diaoluo Mountain, a freshwater turtle called the Big-headed Turtle lives in the mountain streams. Located at the top of the food chain, these turtles have large heads, a hardened layer of skin, a deadly beak, and vicious claws. They are able to climb steep slopes in high altitude streams and take the initiative to attack instead of simply relying on passive defense. They pose a deadly threat to the other creatures in the stream. Watch the video to find more about this ruler of the river.
