Phylum Chordata
Representative Animals: Eagle, sharks, Frogs
Habitat: Habitats have huge variation depending on class, order, family, genus and species.
Reproductive System: Chordates reproduce sexually.
Respiratory System: The respiratory systems of chordates vary depending on the specie. Some chordates have gills (e.g. a shark) but in more advanced chordates the gills are replaces by lungs. It also is linked with weather the animal is found on land or under water. This is evidence of evolution and genetic variation. Chordates use blood as transportation for Oxygen and carbon dioxide. Respiratory pigment is hemoglobin and this is what makes blood the characteristic red colour.
Digestive System: Animals in this phylum have a complete digestive system. Phylum Chordata is where we see the most development of digestive organs and slight variation between species. An example of this being a human pancreas (pancreases are not common between all animals of phylum chordata)

Circulatory System: Species in phylum chordatata have a closed circulatory system and almost all species have a heart - though they will differ in appearance.
Animals like fish have a single loop circulatory system where the blood follows a very simple track.
Other animals have double loop system where both oxygenated and unoxygenated blood will pass through the heart. Crocodilians, birds and mammals have adapted to have separate cavities in the heart hear the oxygenated and unoxygenated blood passes through.

Type of Symmetry: Animals in the phylum chordata all have bilateral symmetry.
Type of Coelom: Animals in phylum chordata are coelomates
Type of Body Plan: Animals in phylum chordata have segmented bodies and are deoterostome (anus develops before the mouth).
Number of body layers: three layers, ectoderm, mesoderm and endoderm.
Specialized Cells: Animals in phylum chordata all have a notochord (backbone). This is the key characteristic that separates them from previous phylums.
