1. Cephalochordate

   A cephalochordate (from Greek: κεφαλή kephalé, "head" and χορδή khordé, "chord") is an animal in the chordate subphylum, Cephalochordata. They are commonly called lancelets. Cephalochordates possess 5 synapomorphies, or primary characteristics, that all chordates have at some point during their larval or adulthood stages. These 5 synapomorphies include a notochord, dorsal hollow nerve cord, endostyle, pharyngeal slits, and a post-anal tail (see chordate for descriptions of each). The fine structure of the cephalochordate notochord is best known for the Bahamas lancelet, Asymmetron lucayanum. Cephalochordates are represented in modern oceans by the Amphioxiformes and are commonly found in warm temperate and tropical seas worldwide. With the presence of a notochord, adult amphioxus are able to swim and tolerate the tides of coastal environments, but they are most likely to be found within the sediment of these communities.Cephalochordates are segmented marine animals that possess elongated bodies containing a notochord that extends the length of the body from head to tail. They are only a few centimeters in length and due to their lack of a mineralized skeleton, their presence in the fossil record is minimal. A few fossils have been found such as the Burgess Shale of British Columbia which contained the fossils of Pikaia, and the Yunnanozoon fossil which also dates back to the Cambrian period.Cephalochordates are thought to have diverged from the rest of the chordate subphylum approximately 700 to 650 million years ago. Phylogeny is based on a combination of studies of extinct and extant species.

1. cephalochordate

   Cephalochordate is a general term for any member of the subphylum Cephalochordata, a group of marine animals that are characterized by a notochord (a flexible, rod-like structure) extending the length of the body, including into the head. They are part of the phylum Chordata and are the closest living relatives to vertebrates. The most well-known cephalochordate is the lancelet, a small, eel-like creature.
