Sponges from the 2010-2014 Paamiut multispecies trawl surveys, eastern Arctic and subarctic : class Demospongiae, subclass Heteroscleromorpha, order Poecilosclerida, families Dendoricellidae and Tedaniidae... : Fs97-6/3282E-PDF

"Sponges (phylum Porifera) are benthic filter-feeding animals that play an important role in nutrient cycling and habitat provision in the deep sea. Sponges collected between 2010 and 2014 during annual multispecies trawl surveys conducted by Fisheries and Oceans Canada (DFO) in Baffin Bay, Davis Strait and portions of Hudson Strait were taxonomically examined. In total ~2500 specimens were identified, comprising over 100 sponge taxa. Sponges from the order Poecilosclerida comprised nearly half the identified species. This report summarizes sponges from the family Dendoricellidae (class Demospongiae, subclass Heteroscleromorpha, order Poecilosclerida) and family Tedaniidae (class Demospongiae, subclass Heteroscleromorpha, order Poecilosclerida). A total of six species are described, from genera Dendoricella (Dendoricellidae) and Tedania (Tedaniidae). These species are: Dendoricella flabelliformis, Dendoricella cf. flabelliformis, Dendoricella aff. flabelliformis, Dendoricella sp. 1, Tedania (Tedania) suctoria, and Tedania sp. 1. Descriptions include morphological and spicule descriptions, spicule dimensions, and taxonomic discussion"--Abstract, p. iv.
