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 Japanese spider crab has the greatest leg span of any arthropod, reaching 5.5 metres (18 ft) from claw to claw. The body may grow to a size of 40 cm or 16 in (carapace width) and the whole crab can weigh up to 19 kilograms (42 lb)âsecond only to the American lobster among all living arthropod species. The males have the longer chelipeds; females have much shorter chelipeds, which are shorter than the following pair of legs.
