Study Notes
Characteristics of Bilateria
- Animals with bilateral symmetry, where the right side is approximately the same as the left side and has a distinct anterior end.
- Can be divided into two equal parts by an imaginary line only in one plane.
- Typically have a clearly differentiated head at the anterior end and a distinct posterior end.
- Have clearly defined dorsal and ventral surfaces.
Phyla Included in Bilateria
- Phyla included in this grade are Platyhelminthes, Nematoda, Annelida, Mollusca, Arthropoda, Echinodermata, Hemichordata, and Chordata.
Echinodermata
- Have developed bilateral symmetry, evident from the study of their larvae structure.
- Adult Echinoderms have secondarily developed radial symmetry due to their special mode of life.
Body Structure
- All animals in grade Bilateria are triploblastic.
- May be acoelomate, pseudocoelomate, or coelomate.
