rotational symmetry with respect to a central axis) like a doughnut (torus). Brittle star – radially symmetrical shape, bilaterally symmetrical movement Radial Symmetry vs Bilateral Symmetry. Radial versus bilateral symmetry is easy to explain. Bilateral is two-sided symmetry and the most common form – 90% of organisms and plants are bilaterally symmetrical. Shimmery comb jellies (right) may have an evolutionary lineage that also predates the time period long thought to represent the first flowering of animal life.

Cool facts: A jelly’s soft shape is perfectly adapted to its environment. The animals thin skin stretches over a body that’s more than 95% water ( no bones or shells to weigh it down) Symmetry: Comb jellies are bilaterally symmetrical Feeding strategy: Jellies are voracious feeders of planktonic organisms, including copepods and fish larvae. They can consume almost 500 copepods per hour. The Ediacaran Eoandromeda could putatively represent a comb jelly.
