ABSTRACT
The use of behavioral data is quite common in studies of chordate animals and some groups of arthropods; however, these data are usually used in ecological and conservation studies. Their use remains uncommon in phylogenetic reconstructions, especially for non-model groups in behavioral studies. This study aims to evaluate the methodological use of behavioral (feeding process) data with EthoKit Logger in the phylogenetic reconstruction of the Cnidaria, a group in the so-called 'lower' Metazoa. The results indicate considerable cohesion with reconstructions based on molecular data available in previous studies. We therefore suggest that the use of behavioral characters can possible be a useful secondary tool or a proof test for molecular evolutionary reconstructions.
