Body Cavity: Coelum - a fluid filled cavity formed within the
mesoderm.
Body Symmetry: Bilateral symmetry- Symmetrical arrangement of an
organism or part of an organism along a central axis, so that the
organism or part can be divided into two equal halves. Bilateral
symmetry is a characteristic of animals that are capable of moving
freely through their environments

Sensory Structures: very highly developed and specialized organs
that are an extension of the central nervous system, with a sole
function to take in information and relate it to the brain. Include
eyes, nose, mouth, etc.Gas Exchange: Mammals inhale oxygen, exhale
carbon dioxide; fish and amphibians use
gillshttp://www.biologycorner.com/resources/fish_gills.jpghttp://3.bp.blogspot.com/_mD3jinJ3a1k/SKr2cA4isWI/AAAAAAAABAc/1g0LfsTXgKs/s400/5-senses.jpgShannon
