WebBilateral symmetry involves the division of the animal through a sagittal plane, resulting in two mirror image, right and left halves, such as those of a butterfly (Figure 2d), crab, or human body. Animals with bilateral symmetry have a “head” and “tail” (anterior vs. posterior), front and back (dorsal vs. ventral), and right and left sides (Figure 3).
WebEach phylum has a unique set of characteristics that define it, most notably in terms of symmetry, digestion, segmentation, and body support. Porifera are asymmetrical, have a single opening and mesohyl for digestion, lack segmentation, and rely on a hardened external skeleton for support.

WebAt a very basic level of classification, true animals can be largely divided into three groups based on the type of symmetry of their body plan: radially symmetrical, bilaterally symmetrical, and asymmetrical. Only a few animal groups display radial symmetry, while asymmetry is a unique feature of phyla Porifera (sponges). WebAnimal Characterization Based on Body Symmetry. At a very basic level of classification, true animals can be largely divided into three groups based on the type of symmetry of their body plan: radially symmetrical, bilaterally symmetrical, and asymmetrical. Asymmetry is seen in two modern clades, the Parazoa ( Figure 27.7 a) and Placozoa.
