      Very interesting hub. I had never heard of this funny-looking marine creature before. From a quick glance, it really does resemble a fat, sluggish dolphin.

      I hadn't heard of them either. But I love manatees and I just checked to see if they're related and they are. They're all part of a group called Sirenia.
