- Ciona adults have rich embodied postural dynamics and are able to perceive different sensory stimuli and respond with distinct behavioral outputs. This has important implications for the evolution of nervous systems and behavior in sessile epibenthic organisms.

- We find evidence of continuous behavioral maturation and provide a quantitative framework for exploring the evolution of behavioral developmental plasticity in chordates.
