Here I will try to share news and insights about marine mammals, marine reptiles, and generally explore the evolution of aquatic amniotes, with special reference to the TRANSITION from terrestrial to aquatic in air-breathing, amnion-bearing, vertebrates. This will involve manatees, whales, dolphins, seals, mosasaurs, sauropterygia, turtles, crocodylians, and other members of the 25+ clades of amniotes that have made the leap, or scuttle, back to the water.
