Abstract

Historically, sponge classification is based on the interpretation of morphological characters, whose phylogenetic information content is frequently limited, subject to homoplasies, or prone to environmental plasticity (e.g., Chombard et al. 1998). Therefore, the currently accepted order-level classification of its largest class, Demospongiae, has been largely revised with molecular phylogenetic data (Morrow & Cárdenas 2015). Nevertheless, numerous sponge genera with ambiguous or provisoric phylogenetic placement still await definite classification.
