Quizplus · Accepted Answer

The sea cucumber (Bohadschia argus) has an anterior-posterior orientation of the mouth and anus, meaning that the mouth is located at one end of the body and the anus is located at the opposite end. This is in contrast to the oral-aboral orientation found in the other animals shown in the figure, where the mouth and anus are located at opposite sides of the central body axis.
