Symmetry in biology Most radially symmetric animals are symmetrical about an axis extending from the center of the oral surface, which contains the mouth to the center of the opposite, , end. Radial symmetry is especially suitable for sessile animals such as the sea anemone, floating animals such as jellyfish, and slow moving organisms such as starfish. Animals in the phyla Cnidaria and Echinodermata are radially symmetric, although many sea anemones and some corals have bilateral symmetry defined by a single structure, the siphonoglyph. Many flowers are radially symmetric or actinomorphic. Roughly identical flower parts – petals, sepals, and stamens – occur at
Phyla lanceolata Phyla lanceolata Phyla lanceolata is a species of flowering plant in the verbena family known by the common name lanceleaf fogfruit or frogfruit. It is native to the southern half of North America, including much of the United States except for the northwestern quadrant, and much of Mexico. It is resident in many types of moist and wet habitat, including disturbed areas, such as irrigation ditches. It is a perennial herb growing decumbent in a matlike form with spreading, trailing stems up to half a meter long, sometimes rooting at nodes. The lance-shaped or nearly oval leaves are up to
