Echinodermi

  1. 1.  Is the highest taxonomic rank of organisms  There wasn’t predict by Limneo and Wittacker Are Eukarya, Bacteria and Archea Domain The domain that we keep in consideration is EUKARYA
  2. 2. Kingdom In biology, kingdom is a taxonomic rank, which is either the highest rank or in the more recent three-domain system, the rank below domain. Since 1969 Whittacker has introduced 5 domain The Kingdom of echinoderm is those of ANIMAL
  3. 3. Phylum In biology, a phylum is a taxonomic rank below kingdom and above class The symmetry of echinoderm is bilateral, the digestive system has 2 opening, it is an metametric organism The Subphylum is called elethorozea
  4. 4. Charateristics Deuterostome embryo development Secondary radial symmetry: larvae have bilateral symmetry Five radial parts; sea cucumbers developed pseudo- bilateral symmetry Endoskeleton: calcite plates (ossicles) covered by epidermis, may be single plates (flexible body) or fused (solid shell, sea urchin) Spines on calcite plates give “spiny skin” (phylum name!) sea urchin spines are endoskeleton and covered by thin skin!
  5. 5. A particoular charateristic: Aquiferous System The aquiferous system is a particular system of vessels that forms the basis for locomotion, the grip on the substrate, the capture of prey and to the respiration of Echinodermata It is based on the principle of osmosis
