Although there is not a singular response of marine amniotes to climate change, individual observations indicate three kinds of interrelated responses of marine amniotes: distribution shifts (geographic ranges), phenological changes (timing of seasonal activities) and interspecific interactions including competition between species and the predator-prey system dynamics.
Like other amniotes (reptiles, dinosaurs, birds, and mammals), they breathe air and do not lay eggs underwater, although many species live in or around water.
"The fact that nearly all living mammals have eye shapes that appear 'nocturnal' by comparison with other amniotes [mammals, reptiles and birds] is a testament to the strong influence that evolutionary history can have on modern anatomy," said Chris Kirk, associate professor of anthropology at The University of Texas at Austin.
