Overview. Complex carbohydrates are made up of sugar molecules that are strung together in long, complex chains. Complex carbohydrates are found in foods such as peas, beans, whole grains, and vegetables. Both simple and complex carbohydrates are turned to glucose (blood sugar) in the body and are used as energy.
A turtle is an animal in armor. Much of its body lies within a protective shell, which has openings for the turtle's four chunky legs, short tail, and head. When danger threatens, many turtles pull legs, tail, and head into the shell.
Sea Turtle History. The oldest fossils of turtles were found in Germany and date back 215 million years, during the Triassic period. 1 They are among the oldest fossils of four-legged animals and one of the Earthâs most ancient creatures.These ancestral turtles had completely formed shells and lived on land, in marshes.here are two groups of sea turtles: Dermochelyidae, including the Leatherback, are the most ancient sea turtles, the largest, and the only sea turtles without a hard shell; Cheloniidae, including the other six types of sea turtle, vary in size but all have a hard shell.
