| | Human Embryo Gill Slits, CARM |
 | | Most, if not all, textbooks will refer to the structures as pharyngeal poiuches, but they will also give you the common name which is gill slits or clefts. | | | The gill slits is where rich Americans cut off a fishes head before they cook and eat it (we just don't have the palate to appreciate the head). | | | To insist on calling the mammalian structure a gill slit, is to suggest gills which we all know are not there at all. |

| | They are united by having, at some stage in their life, a hollow dorsal nerve cord (the notochord), pharyngeal slit s, a tail extending past the anus, and bands of muscles that go around the body. | | | Cephalochordates have a notochord and a nerve cord but no vertebra and in vertebrates the notochord has been replaced by a bony vertbral column. | | | Chordates ( phylum Chordata) include the vertebrate s, together with several closely related invertebrate s. |

| | They are united by having, at some stage in their life, a hollow dorsal nerve cord (the notochord), pharyngeal slit s, a tail extending past the anus, and bands of muscles that go around the body. | | | One in the subphylum urochordata, one in the subphylum cephalochordata, and eight in the subphylum vertebrata. | | | The traditional classification of vertebrates contains a wide variety of paraphyletic groups, which in newer systems may either be abandoned or greatly extended. |
