Abstract
    Bioluminescence is the ability to produce visible light and is generated by a biochemical reaction. Among echinoderms, many ophiuroids harbour this capability. Another amazing characteristic of echinoderms is their ability to regenerate. In this work, the luminescence capability of the brittle star Amphiura filiformis is used as an indicator of functional recovery of regenerated arms. Regeneration was experimentally induced and followed for a period of 45 to 60 days post amputation. Different pharmacological stimuli were used and both morphological and luminous parameters were analysed. Analysis shows a rise in KCl-induced luminescence between 45 and 55 days. Luminescence of regenerated arms obtained with neurotransmitter applications showed more variability. This study suggests that morphological recovery seems to be almost complete within 60 days while nervous control of luminescence is still not fully restored.
