While there have been mammals that returned to the sea, none of them evolved so as to lose their lungs and re-evolve gills. Since lungs are essential for land vertebrates (or at least vertebrates of any size - very small animals, like worms, nematodes, etc, can still obsorb enough oxygen through their skin to support metabolism; larger land animals require lungs and a circulatory system), unless batfish have lungs, I'm skeptical of a claim that it evolved from a land animal.
I was hoping I can evolve with gills, so I don't have to worry about dive table and scuba gears, or paying scuba shops and airfare. Now my dream is shattered....
Last year at Cozumel, my friends saw one during an afternoon dive. Too bad I wasn't with them. I hope I can see one this year.
