Marine Reptiles Class Reptilia

Reptile Characteristics Ectothermic Highly developed nervous system Amniotic egg Scaly skin – decreases water loss in marine environments

Taxonomy Class Reptilia

Amniotic Egg Allows a few things Development within egg can happen longer Less vulnerable to predation than a larval stage Can lay eggs on dry land – what is the term for this?

Amniotic Eggs Amnion – liquid-filled sac in which the embryo develops Yolk sac – food supply Allantois - waste disposal Chorion - surface for gas exchange

Types of Marine Reptiles Marine Crocodiles Sea Turtles Marine Iguana Sea Snakes
