Sea squirt reveals glowing spines and unexpected nervous system anatomy

Ascidians, also known as sea squirts, are the evolutionary link between vertebrates and invertebrates, making them valuable subjects of biological studies. For the first time, researchers at Ruhr University Bochum have detected pronounced autofluorescence in Halocynthia papillosa, one of more than 3,000 species. Furthermore, the study provides comprehensive insights into the anatomy of this sea squirt.
