Title: Birds evolving from fish, a possibility? Written by: duddy on Sep 29, 2013 (https://biology-forums.com/gallery/47/4_29_09_13_5_33_58.jpeg) (https://biology-forums.com/index.php?action=gallery;sa=view;id=14087) A flying fish moves its tail up to 70 times per second to propel itself up and out of the water. Those specialised pectoral fins are spread wide and tilted slightly upward to provide lift, and then folded back against the body to lower the fish back into the ocean. Flying fish (family: Exocoetidae) are eaten by dolphins, tuna, birds, squids and porpoises, so they needed to develop an ingenious mode of escape - such as flying - in order to survive.
