Ctenophora morphology
WebMorphological characteristics (such as skin color, body shape, etc.) may evolve multiple times, and independently, through evolutionary history. Analogous characteristics may appear similar between animals, but their underlying evolution may be very different. We sampled ctenophores from locations around the world (Table 1), mostly between 2013 and 2016. Ctenophore specimens were identified to as low a taxonomic level as possible (Table 1). Many newly sequenced species, particularly those sampled from Antarctica, were undescribed species.
