Adult lancelets retain the four key features of chordates: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail. Second, the Deuterostomia branch lineage is the most commonly considered because developmental, structural, and biological links were established. One unique feature is that the notochord and nerve cord, which are found along the entire length of the body, persist throughout life even in the adult phase. The notochord is part of the skeletal system while the dorsal nerve cord is part of the central nervous system. Animals obtain food by ingestion, and fungi obtain food by absorption. You discover an organism that has scaly skin and is aquatic but returns to the land to reproduce.

Find the misspelled word in given sentence. In chordates, there is only one dorsal nerve cord. They are often called lancelets because of the shape of their bodies. Craniata means skull in Greek, which is fitting as they are the only subphylum with skulls developed specifically to hold a brain. The purpose of the notochord is to provide a substrate for organs to attach to and create a fixed structure and shape for the organism to take hold.
