but youll maybe recognise it anyway, that for the last 10-20 million years has crawled on its belly and its small fins up from the water it lives in for a journey out in the swamps , thus in most cases enabling its death, (it has no structure that even resembles a leg and it has no lungs), shouldnt natural selection making it easy for this poor fish.

Periopthalmus, the mudskipper, has no lungs and its fin does not resemble a leg. However it leads a ahappy life in the tropical mangrove forests, looking for food in the muddy beaches.
Periopthalmus can breathe air as long as its gills are wet.
