Background Lithistid demosponges, also known as rock sponges, are a polyphyletic group of sponges which are widely distributed. In the Northeast Atlantic (NEA), 17 species are known and the current knowledge on their distribution is mainly restricted to the Macaronesian islands. In the Mediterranean Sea, 14 species are recorded and generally found in marine caves. Methods Lithistids were sampled in nine NEA seamounts during the scientific expeditions Seamount 1 (1987) and Seamount 2 (1993… 
Sponges of Western Mediterranean seamounts: new genera, new species and new records
TLDR
Following the Sponge Barcoding project goals, the Cytochrome Oxidase subunit I (COI) and the 28S ribosomal fragment (C1–D2 domains) for Foraminospongia balearica sp.
High diversity of siliceous sponges in Western Tethyan areas during the Eocene: palaeobiogeographical, ecological and taxonomic significance
Porifera is a clade of globally distributed, early diverging metazoans that are important components of modern aquatic environments. Despite the fact that they were also abundant in the geological
Diversity, Distribution and Phylogenetic Relationships of Deep-Sea Lithistids (Porifera, Heteroscleromorpha) of the Azores Archipelago
TLDR
The diversity and distribution of lithistid sponges of the Azores archipelago are investigated based on historical records and examination of samples accidentally collected during deep-sea longline fishing operations in the region, and molecular barcodes are provided for seven species.
Lithistid Demosponges of Deep-Water Origin in Marine Caves of the North-Eastern Mediterranean Sea
Desmas-bearing demosponges known as lithistids have heavily silicified skeleton and occur typically in bathyal environments of warm and tropical areas but may be found in certain shallow marine

A new species of Macandrewia (Demospongiae, Tetractinellida, Macandrewiidae) from a seamount in the Western Pacific Ocean
TLDR
A new species of Macandrewia Gray from a seamount near Yap Trench in the Western Pacific Ocean was described and a partial sequence of COI gene was obtained from the new specimen and then it submitted to GenBank.

Two new lithistids (Porifera: Demospongiae) from a shallow eastern Mediterranean cave (Lebanon)
TLDR
Two new species of lithistid sponges are described from a submarine cave, depth 2–3 m, in Lebanon, which are interpreted as remnants of a warmer period in the Mediterranean that survived the subsequent cooling only in the warmer eastern basin.
Lithistid sponges of the upper bathyal of Madeira, Selvagens and Canary Islands, with description of a new species of Isabella
TLDR
In this study the lithistids collected in the course of the Harbor Branch Oceanographic Institute eastern Atlantic 1991 campaign to Madeira, Selvagens and the Canary Islands were identified and assigned to eight species, representing eight genera and five families.
Systematics of ‘lithistid’ tetractinellid demosponges from the Tropical Western Atlantic – implications for phylodiversity and bathymetric distribution
TLDR
This first integrative approach of TWA ‘lithistid’ demosponges contributes to a better understanding of their phylogenetic affinities, diversity and bathymetric distribution patterns within the TWA.

TLDR
The number of lithistid sponges reported from the tropical western Atlantic region to 30 species is increased, but the unpublished data suggest a much higher number of species present in this region.
A new carnivorous sponge, Chondrocladia robertballardi sp. nov. (Porifera: Cladorhizidae) from two north-east Atlantic seamounts
TLDR
A new species of Carnivorous sponges (Porifera: Cladorhizidae) is described from specimens collected on two large north-east Atlantic seamounts – the Gorringe and Galicia Banks – located off the Iberian Peninsula.
Sponges of the Guyana Shelf.
TLDR
Thirtysix species were found to be new to science, excluding the first Central West Atlantic record of the genus Halicnemia, not named at the species level because of lack of sufficient material.

Rare sponges from marine caves: discovery of Neophrissospongia nana nov. sp. (Demospongiae, Corallistidae) from Sardinia with an annotated checklist of Mediterranean lithistids
TLDR
The discovery of a new record of lithistid demosponges from a western Sardinian karstic cave stresses the key status of Mediterranean palaeoendemics as possible remnants of an ancient Tethyan fauna and focuses the need to plan conservation measures for these rare cave-dwelling sponges.
Systematic revision of the genus Petromica Topsent (Demospongiae: Halichondrida), with a new species from the southwestern Atlantic
TLDR
The status, scope and classification of the sublithistid demosponge genus Petromica Topsent are revised through morphological analysis of museum specimens of all seven species (including proposed synonyms and varieties), and three forms described as varieties of Monanthus plumosus Kirkpatrick are raised to species level.
Harpacticoida (crustacea, copepoda) of the great meteor seamount, with first conclusions as to the origin of the plateau fauna
Qualitative samples were taken at 26 stations on the Great Meteor Seamount and in the surrounding deep sea in order to record the meiofauna and to allow first qualitative faunistic investigations.
