A small ampulla; a very small flask-shaped or bulbous structure.
From Latin ampulla (flask) + -ula (diminutive suffix meaning 'small'). This creates a doubly specific term for tiny flask-shaped anatomical structures.
Ampullulae in sea stars and brittle stars are absolutely tiny sensory organs, yet they help these creatures detect light and navigate their ocean homes—proof that even microscopic structures can be essential for survival.
