Callyspongia (Cladochalina) aculeata, commonly known as the branching vase sponge is a species of sea sponge in the family Callyspongiidae.

Then, during the German Deep Sea Expedition "Valdivia" (1898-1899), Schulze described the largest known siliceous hexactinellid sponge, the up to three metres high Monorhaphis chuni. This sponge develops the also largest known bio-silicate structures, giant basal spicules, three metres high and one centimetre thick.
Callyspongia crassa, commonly known as prickly tube-sponge, is a species of sponge found from the Red Sea to the Seychelles.Its wide flexible brown tube with exterior protuberances can appear as a single tube or as clusters of tubes and can reach up to 50 centimeters (20 inches) in size.
The latest find is fossil-feeding sea sponges. Scientists are discovering alien-like worlds in the uncharted oceans of the Arctic and Antarctica. The latest find is fossil-feeding sea sponges.
If temperature-tracking sea sponges are to be trusted, climate change has progressed much further than scientists have estimated. A new study that uses ocean organisms called sclerosponges to ...
Spongia officinalis, better known as a variety of bath sponge, is a commercially used sea sponge.
