(2017) Sponges from the 2010-2014 Paamiut Multispecies Trawl Surveys, Eastern Arctic and Subarctic: Class Demospongiae, Subclass Heteroscleromorpha, Order Poecilosclerida, Family Coelosphaeridae, Genera Forcepia and Lissodendoryx. Canadian Technical Report of
Fisheries and Aquatic Sciences 3224: v + 129.
Sponges (Phylum Porifera) are benthic filter feeding animals that function 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 known sponge taxa. Sponges from the Order Poecilosclerida comprised nearly half the identified species. This report summarizes sponges in the Family Coelosphaeridae (Class Demospongiae, Subclass Heteroscleromorpha, Order Poecilosclerida, Family Coelosphaeridae) which is the most specious family of poecilosclerid sponges in the collections. Sixteen species are described from the genera Forcepia and Lissodendoryx: Forcepia (Forcepia) fabricans, F. (F.) forcipis, F. (F.) forcipula, F. (F.) aff. japonica, F. (F.) thielei, Forcepia (Leptolabis) cf. brunnea, Forcepia sp. 1 and Forcepia sp. 2, Lissodendoryx (Lissodendoryx) complicata, L. (L.) indistincta, L. (L.) lundbecki, L. (L.) stipitata, Lissodendoryx (Ectyodoryx) cf. diversichela, L. (E.) cf. foliata, L. (E.). cf. multiformis, Lissodendoryx sp. 1. Descriptions include morphological and spicule descriptions and dimensions, DNA barcodes and taxonomic discussion.
