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.
The sea lion has flippers in place of where its feet would be in order to help the sea lion move through water quickly, a substance that is eight times denser than air. 1  In each flipper of the sea lion there are five skeletal digits, like toes, that give the sea lion more movement in its flippers but these are not always visible.
