Amniotes, Eumetazoa, Bilateria, Lophotrochozoa, Ecdysozoa, Deuterostomia,…
Amniotes
limbed vertebrates (tetrapods) defined by an embryo protected by special extra-embryonic membranes
Eumetazoa
a major animal clade encompassing all multicellular animals with true tissues, neurons, and a gastrula stage
Bilateria
animals characterized by bilateral symmetry and generally three germ layers
Lophotrochozoa
Organisms with
lophophores
or trochophore larvae
Ecdysozoa
One of the three main lineages of bilaterian animals; many animals
molt
Deuterostomia
a major superphylum of Bilaterian animals defined by embryological development where the blastopore becomes the anus, not the mouth.
Kingdom level clade, to include all multicellular animals
Metazoa
Porifera
Lack tissue, Have Choanocytes (collar cells-flagellated cells that ingest bacteria and tiny food particles.)
Syndermata
Hemocoel; rotifers have alimentary canal (digestive tract with mouth and anus) and jaws (trophi); acanthocephalans are parasites of vertebrates
Plathyhelminthes
No body cavity; dorsoventrally flattened; gastrovascular cavity or no digestive tract.
Mollusca
Hemocoel; reduced coelom; three main body parts (muscular foot, visceral mass, mantle); most have hard shell made of calcium carbonate
Cnidaria
Unique stinging structures (nematocytes) housed in specialized cells (cnidocytes) diploblastic, radially symmetrical; gastrovascular cavity (digestive compartment with a single opening
Ectoprocta
Coelom; have lophophores (feeding structures bearing ciliated tentacles)
Annelidia
Coelom; body wall and internal organs are segmented (except digestive tract, which is unsegmented)
Nematoda
Hemocoel; cylindrical body with tapered ends; no circulatory system; undergo ecdysis
Arthropoda
Hemocoel; reduced coelom. Have segmented body, jointed appendages, and exoskeleton made of protein and chitin
Echinodermata
Coelom; bilaterally symmetrical larvae and five-part body organization as adults; unique water vascular system; endoskeleton
Chordata
Coelom; have notochord; dorsal, hollow nerve cord; pharyngeal slits; post-anal tail
Cephalochordata
Lancelet; small marine chordates lacking a backbone
Urochordata
Tunic; outer covering made of tunicin
Vertebrates
Gnathostomes
Actinopterygii
Ray-finned; thin bone rays
Lobe-fin
Dipnoi
True lungs; modified swim bladder functioning as lungs
Actinistia
Oil filled swim bladder; fatty oils instead of gas
Lobed fins; rod-shaped muscular fins
Amphibia
Moist skin; used for gas exchange through skin
Reptilia
Scaly skin; prevents water loss
Mammalia
Fur; covers skin for warmth and protection
Chondrichthyes
Cartilage skeleton; skeleton made of cartilage instead of bone
Acanthidii
Prominent fin spine; fins supported by bony spine
Placodermi
Armored plates on head+thorax; bony dermal cover
Jaws; hinged structures for grabbing onto food
Myxini
Slime glands; produces slime as defense
Cyclostome
Petromyzontida
Seven gill pouches; openings on side of body
Jawless mouth; sucker like opening instead
Tetrapod
Neck; independent head movement
Osteichthyans
Opercolum; bony flap that protects gills
Cranium; skull made of cartilage
Body symmetry: radial, bilateral, and asymmetrical
Body plans: characterized by symmetry, tissue organization, body cavities (coelom, hemocoel, and no cavity), and shared derived characteristics.
