Dorsal hollow nerve cord: derives from ectoderm that rolls into hollow tube. Located at top of the animal. Embryo develops into the brain and spinal cord, which comprise the central nervous system.
2. Notochord: flexible, rod shaped structure found in embryonic stage. It gives chordates skeletal support through length of body. Located between digestive tube and nerve cord. Primary axial support of the body throughout lifetime.
3. Pharyngeal slits
4. Post-anal tail

Tri: Possess bilateral symmetry. (ectoderm, endoderm, mesoderm)
- Ectoderm: external layer develops nervous system, external sensory organs of the hair and skin glands.
- Mesoderm: middle layer forms connective tissue, cartilage, muscle, blood vessels, lymphatics, notocord, pericardium, kidneys, gonads.
- Endoderm: innermost layer, epithelium, respiratory tract, digestive tract, bladder and urethra are formed.

Diploblastic: cnidaria possess two germ layers. (ectoderm and endoderm)

- All animals except porifera, cnidaria, and ctenophora have 3 germ layers. Triploblastic have become dominant because advantages by having coelom (body cavity, protects organs from external pressure, increasing strength and speed, organs to develop at diff rates)
- Others are more simple such as acoelomates]]> 2017-11-09 06:33:55 UTC https://padlet.com/brookemigdal/9jafha7gkg10/wish/205143600 adonis10brown https://padlet.com/brookemigdal/9jafha7gkg10/wish/205344887 2017-11-09 16:06:08 UTC https://padlet.com/brookemigdal/9jafha7gkg10/wish/205344887
