From Latin centrum (center) + Greek axōn (axis) + -ia (condition suffix). A technical term used in biology and paleontology.
Most sea creatures with centraxonia symmetry live in the deep ocean where we can barely see them—our understanding of these animals has exploded only in the last 20 years with better underwater cameras.
