Arthropods and vertebrates2
Skeletons2
Chordata1
Skeleton4
  • Cartilage in the joints is one of the few locations in the vertebrate skeleton that normally remains unmineralized. (stanford.edu)
  • Characteristic of the vertebrate form, the human body has an internal skeleton that includes a backbone of vertebrae. (rincondelvago.com)
  • They have a backbone, scales, lay eggs to reproduce, and have an internal skeleton. (thetrellis.com)
  • A minibeast, also called an invertebrate , is a creature without either a backbone or an internal skeleton. (mylearning.org)
Vertebral column4
  • All vertebrates are built along the basic chordate body plan: a stiff rod running through the length of the animal (vertebral column and/or notochord), with a hollow tube of nervous tissue (the spinal cord) above it and the gastrointestinal tract below. (wikipedia.org)
  • With only one exception, the defining characteristic of a vertebrate is the vertebral column, in which the embryonic notochord found in all chordates is replaced by a segmented series of mineralized elements called vertebrae separated by fibrocartilaginous intervertebral discs, which are derived embryonically and evolutionarily from the notochord. (wikipedia.org)
  • Hagfish are the only extant vertebrate whose notochord is not integrated into the vertebral column. (wikipedia.org)
  • Unlike vertebrates, tunicates lack a backbone or vertebral column. (newworldencyclopedia.org)
Mammals1
  • Mammals are another type of vertebrate that belong to the class Mammalia . (yourdictionary.com)
Hollow dorsal nerv2
Warm-blooded1
Echinoderms1
  • He suggested that chordates are most closely related to echinoderms, and that lancelets, tunicates, and vertebrates independently evolved from a Paleozoic group of asymmetrical calcified organisms called carpoids (today named Homalozoa - Stylophora , including the subgroups Soluta , Cornuta , and Mitrata ), which were usually considered as oldest and most basal echinoderms. (evolutionnews.org)
Unlike1
Tunicates4
  • Tunicates and not cephalochordates are the closest living relatives of vertebrates. (palass.org)
  • An interesting twist to this whole story was based on the circumstance that the opponents of the calcichordate hypothesis considered as their most substantive critique that this hypothesis implies a closest relationship of tunicates with vertebrates, which was generally considered as refuted by numerous independent phylogenetic studies ( Peterson 1995 , Donoghue et al. (evolutionnews.org)
  • for an opposing view) surprisingly suggested that tunicates are indeed closer related to vertebrates. (evolutionnews.org)
  • Even though the calcichordate hypothesis correctly predicted a sister group relationship of tunicates and vertebrates, it also relies on a sister group relationship of echinodermates and chordates that was refuted by modern phylogenomics, which rather suggests that echinodermates are the sister group to hemichordates. (evolutionnews.org)
Hagfish2
  • The vertebrates traditionally include the hagfish, which do not have proper vertebrae due to their loss in evolution, though their closest living relatives, the lampreys, do. (wikipedia.org)
  • Molecular analysis since 1992 has suggested that hagfish are most closely related to lampreys, and so also are vertebrates in a monophyletic sense. (wikipedia.org)

Subphylum1
  • For this reason, the vertebrate subphylum is sometimes referred to as "Craniata" when discussing morphology. (wikipedia.org)
