  animalia WKP
  Definition: Animals are multicellular, eukaryotic organisms of the kingdom Animalia (also called Metazoa). The animal kingdom emerged as a clade within Apoikozoa as the sister group to the choanoflagellates.
  Animals are motile, meaning they can move spontaneously and independently at some point in their lives. Their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later in their lives.
  All animals are heterotrophs: (...)

  Adj. mesenchymal WKP
  Definition: Mesenchyme is a type of tissue characterized by loosely associated cells that lack polarity and are surrounded by a large extracellular matrix.
  Mesenchymal cells are able to develop into the tissues of the lymphatic and circulatory systems, as well as connective tissues throughout the body, such as bone and cartilage.

  Deuterostome WKP
  Defintion: Deuterostomes (taxonomic term: Deuterostomia; meaning "second mouth" in Greek) are any members of a superphylum of animals. It is a sister clade of Protostomia, with which it forms the Nephrozoa clade.
  Deuterostomia is a subtaxon of the Bilateria branch of the subkingdom Eumetazoa, within Animalia, and are distinguished from protostomes by their deuterostomic embryonic development.
  In deuterostomes, the first opening (the blastopore) becomes the anus, (...)

• chordates
  3 March 2017

  WKP
  Definition : A chordate is an animal belonging to the phylum Chordata; chordates possess a notochord, a hollow dorsal nerve cord, pharyngeal slits, an endostyle, and a post-anal tail, for at least some period of their life cycle.
  Chordates are deuterostomes, as during the embryo development stage the anus forms before the mouth.
  They are also bilaterally symmetric coelomates with metameric segmentation and a circulatory system. In the case of vertebrate chordates, the notochord is (...)
