It is hypothesized that this process is an adaptation for a predatory lifestyle. It is primarily seen in bilaterally symmetrical animals; however, some radially symmetrical animals such as hydras have a primitive form of it. It is present in planarians as two nodes located at the front of a ladder shaped system. Some echinoderms exhibit it in the larval stage, while the sea cucumber retains it as an adult. FTP, name this evolutionary process in which sense organs and a central nervous system concentrate in the head of an animal.          |
