An understanding of ctenophore biology is critical for reconstructing events that occurred early in animal evolution. The phylogenetic relationship of ctenophores (comb jellies) to other animals has been a source of long-standing debate. Until recently, it was thought that Porifera (sponges) was the earliest diverging animal.
