The aquiferous system is an essential character of poriferans and supports their monophyly. Within the Calcarea, this system displays its greatest variety and traditionally is classified as: asconoid, syconoid, sylleibid, and leuconoid. Species of Leucascus, however, present a different type of aquiferous system composed of anastomosed (interconnected) choanocyte tubes and have an atrium lacking choanoderm. There is such confusion about the classification of the aquiferous system of Leucascus… 

Anatomy and ultrastructure of the tropical sponge Cladocroce caelum (Haplosclerida, Demospongiae)

TLDR
The anatomy and ultrastructure of the tropical demosponge Cladocroce caelum (Haplosclerida, Demospongiae) is investigated using light and electron microscopy to better comprehend the physiology, development, and adaptation to the environmental conditions where the species is found.

A monograph of the calcareous sponges (Porifera, Calcarea) of Greenland

  • H. Rapp
  • Environmental Science
    Journal of the Marine Biological Association of the United Kingdom
  • 2013
TLDR
Greenland has more than 200 years of history of studies of the sponge fauna and is the type locality for a number of species, but as the type material has been hard to find or even lost, their taxonomic status has remained uncertain.

Associated organisms inhabiting the calcareous sponge Clathrina lutea in La Parguera, Puerto Rico

TLDR
The goal of this study was to characterize infaunal assemblages from a calcareous sponge, Clathrina lutea, across multiple reefs from the La Parguera Natural Reserve, Puerto Rico, with the most abundant associated fauna being copepods and polychaetes.

Molecular Phylogenetic Evaluation of Classification and Scenarios of Character Evolution in Calcareous Sponges (Porifera, Class Calcarea)

TLDR
The taxonomy of Calcarea is in desperate need of a thorough revision, which cannot be achieved by considering morphology alone or relying on a taxon sampling based on the current classification below the subclass level, according to the results.

Associated organisms inhabiting the calcareous sponge Clathrina lutea in La Parguera Natural Reserve, Puerto Rico

TLDR
The goal of this study was to characterize infaunal assemblages from a calcareous sponge, Clathrina lutea, across multiple reefs from the La Parguera Natural Reserve, Puerto Rico, with the most abundant associated fauna being copepods and polychaetes.

A molecular phylogeny for the order Clathrinida rekindles and refines Haeckel's taxonomic proposal for calcareous sponges.

TLDR
This study confirms the suitability of skeleton and body anastomosis as valid characters in a phylogenetically sound taxonomy for the order Clathrinida, and finds that Haeckel's original proposal is remarkably similar to the author's own, which was based on a molecular phylogeny 140 years later.

Three-dimensionally preserved soft tissues and calcareous hexactins in a Silurian sponge: implications for early sponge evolution

TLDR
The unusual preservation of the spicules of C. pedicula reveals an originally calcareous composition, which would be diagnostic of the living Class Calcarea, indicating that the last common ancestor of Porifera was a spiculate, solitary, vasiform animal with a thin skeletal wall.

Sponge digestive system diversity and evolution: filter feeding to carnivory

TLDR
This work focuses on the diversity and evolution of sponge nutrition systems and the amazing adaptation to carnivory.

BASAL METAZOANS

TLDR
Morphological, evolutionary, internal and external phylogenetic aspects of the four phyla, including Porifera, Cnidaria, Placozoa and Ctenophora, are highlighted and discussed.
