Sceptrulophora
Sceptrulophora (from Ancient Greek, σκῆπτρον, ''skêptron'' - "sceptre" and -φόρος, ''-phóros'' - "bearing") is an order of hexactinellid sponges, commonly known as Glass sponges, characterized by sceptrule spicules, that is, "microscleric monactinal triaxonic spicules that include clavules with terminel umbels or smooth heads." Species of the order Sceptrulophora have existed since the Jurassic period, and still flourish today. While there is ongoing debate about the organization of various taxa in Sceptrulophora, the monophyly In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic grou ... of the taxon Sceptrulophora is supported by the presence of sceptrules in most of the extant species, and has recently been further supported by DNA sequencing.MARTIN DOHRMANN, CHRISTIAN GÖC ...

Sponges
Sponges, the members of the phylum Porifera (; meaning 'pore bearer'), are a basal animal clade as a sister of the diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells. Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process. Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes. Sponges were first to branch off the evolutionary tree from the last common ancestor of all animals, making them the sister group of all other animals. Etymology The term ''sponge'' derives from the Ancient Greek word ( 'sponge'). Overview Sponges are similar to other animals in that they are multicellular, h ...
