Examples

• The actinomorphies of sea stars make them recognizable from any angle.
• Botanists study the actinomorphies of flowers to classify plant families.
• The actinomorphies observed in these organisms suggest evolutionary adaptation to their environment.
• Unlike zygomorphic flowers, those displaying actinomorphies can be divided into identical halves along multiple axes.
