SPECIMENS of this sponge collected at Calf Sound, Isle of Man, were investigated for spicules, and for their arrangement in the body of the sponge. Six types of spicules were found, ranging from ...

During this time, soluble calcium carbonate and silica were formed by reaction with atmospheric carbon dioxide. These reactions provided silicic acid in seawater-the necessary starting material for ...

“Artificial glassy fibers are brittle because they lack organics,” said Dr. Hermann Ehrlich of the Institute of Bioanalytical Chemistry at Dresden University of Technology in Germany. “Sponge spicules ...

Sponges (Porifera), the phylogenetically oldest, multicellular organisms (Metazoa) are able to transduce light inside their bodies by employing amorphous, siliceous structures.

Spicules are structural elements found in most sea sponges. They provide structural support and deter predators. They are very hard, prickly, and even quite difficult to cut with a knife.

In 1898 I pointed out certain resemblances to the relations between a symbiotic organism and its host in the relations between a crystal, utilised as a spicule, and the sponge which has secreted ...

Today, nearly all sponges are siliceous. ... Moreover, since sponge spicules contain lots of water, they would automatically block the infrared light most commonly used for telecommunications.

April 26 (UPI) --New research suggests ocean sponges aren't as sedentary as once thought. Recent surveys of the Arctic seabed revealed trails of light brown sponge spicules, needle-like support ...

But unlike human crews, sponge cells don’t have any architectural plans to draw from. Instead, they somehow organise themselves and their spicules, likely behaving by very simple rules that ...

At around 11,000 years old, the sponge had lived to see a lot of change as it quietly grew at a depth of approximately 1,100 meters (3,609 feet) in the East China Sea until it was discovered in 1986.
