Sea turtles are reptiles. Sea turtles have long flippers (unlike turtles that live in freshwater, which have webbed feet) that act like paddles to propel them through the water. These flippers help make sea turtles more hydrodynamic (they move through water better). Sea lions are mammals. Sea lions also have long flippers to help propel them through the water. Are the long flippers of sea turtles and sea lions homologous structures or analogous structures? Are the long flippers of sea turtles and sea lions an example of convergent evolution? Explain your answers (hint: the two questions are related).

Marine Evolution

Marine habitat is less explored, and hence, its biological diversity is far less known. The marine habitats are not constant due to their shifting nature, while the terrestrial habitats are more stable. Marine biology is the science that deals with the study of diverse marine species, their interactions, and behavioral characteristics.
