Carnivorous sponges of the Atlantic and Arctic Oceans. Phylogeny, taxonomy, distribution and microbial associations of the Cladorhizidae (Demospongiae, Poecilosclerida)
Hestetun, Jon Thomassen (Doctoral thesis, 2016-11-29)The sponges (phylum Porifera) are defined by the presence of an aquiferous system in which choanoflagellate cells create a current and filter water flowing through the sponge body. The carnivorous sponges represent the ... -
The cladorhizid fauna (Porifera, Poecilosclerida) of the Caribbean and adjacent waters
Hestetun, Jon Thomassen; Pomponi, Shirley A.; Rapp, Hans Tore (Peer reviewed; Journal article, 2016-10-19)The carnivorous sponge family Cladorhizidae has been subject to several recent studies, yet the cladorhizid fauna of the Caribbean and adjacent areas remain comparatively poorly known. In this article we provide a description ... -
Deep-Sea Carnivorous Sponges From the Mariana Islands
Hestetun, Jon Thomassen; Rapp, Hans Tore; Pomponi, Shirley (Peer reviewed; Journal article, 2019-07-10)Carnivorous sponges belonging to family Cladorhizidae (Porifera, Demospongiae, Poecilosclerida) are unique within phylum Porifera due to their ability to capture and envelop small prey. While other sponges use an aquiferous ... -
The Microbiome and Occurrence of Methanotrophy in Carnivorous Sponges
Hestetun, Jon Thomassen; Dahle, Håkon; Jørgensen, Steffen Leth; Olsen, Bernt Rydland; Rapp, Hans Tore (Peer reviewed; Journal article, 2016-11-09)As shown by recent studies, filter-feeding sponges are known to host a wide variety of microorganisms. However, the microbial community of the non-filtering carnivorous sponges (Porifera, Cladorhizidae) has been the subject ...
