Having no axis or not arranged around a central axis; lacking the typical symmetrical organization found in most organisms.
From Greek 'an-' (without) + 'axis' (axle, center line). The prefix 'an-' meaning 'not' or 'without' was combined with the Latin 'axis' to describe biological structures lacking a central organizing line.
Some sea creatures like sponges are anaxial—they have no head-to-tail organization like most animals do, which is why they can grow in weird blob shapes and still function perfectly!
