Grantia Sponge

Grantia Sponge

Sponges, colonial animals in the phylum Porifera, are primitive invertebrates that are dominated by marine species. Typically, they are benthic, sessile filter feeders that are asymmetrical. Grantia is a genus of calcareous marine sponges that is sometimes referred to as Scypha in older texts. This group of sponges demonstrates the sycon body plan in which the wall of the colony is folded into a series of internal and external canals that circulate water to bring in dissolved oxygen and prey while removing waste products.
