What are the skeleton components possibly made of that sponges may have although sponges do not have a skeletal system?

Although sponges do not have a skeletal system they do have skeleton components that may be made of silicon or lime. A sponge is found in the ocean and is a hollow tube that has several large pores throughout it.


Would a sharpie marker be able to write on a yellow sponge?

Yes, a Sharpie marker can write on a yellow sponge. The ink is designed to adhere to various surfaces, including porous materials like sponge. However, the effectiveness of the writing may vary depending on the texture and absorbency of the sponge, and the ink may bleed or spread due to the sponge's porous nature.


Why are spicules used as a primary characteristic in taxonomy of sponges?

Spicules are microscopic structures that are unique to each sponge species, making them a valuable taxonomic characteristic for identifying and classifying sponges. They can vary in shape, size, and composition, providing detailed information about the sponge's classification and evolutionary history. This makes spicules a key feature for distinguishing between different sponge species.


If a living sponge in pieces each piece may produce another sponge?

"yes", If you take a piece off of a sponge it will grow another sponge.


Does the brand of the sponge affect how much water it absorbs?

The brand of a sponge typically does not directly affect how much water it absorbs. The absorption capacity of a sponge is primarily determined by its material composition, density, and pore structure. However, different brands may use varying materials and manufacturing processes that can indirectly impact absorption efficiency. It is essential to consider these factors rather than solely relying on the brand name when selecting a sponge for optimal water absorption.


What is the fate of spongo cell during development in canal system?

During the development of the canal system in sponges, spongo cells, or spongocytes, play a crucial role in synthesizing and secreting spongin, the fibrous protein that forms the sponge's supportive skeleton. As the sponge matures, spongo cells can differentiate or transform into other cell types, contributing to the overall structure and function of the sponge. Ultimately, spongo cells may either remain active in producing spongin or undergo apoptosis as the sponge's architecture stabilizes. Their fate is integral to maintaining the sponge's integrity and adaptation to its aquatic environment.


Can oil float on a sponge?

Yes, oil can float on a sponge, as sponges are typically made of porous materials that can absorb liquids. However, the oil will not be absorbed in the same way that water would be, due to oil's lower density and different chemical properties. Instead, the oil may rest on the surface of the sponge or fill its pores without being fully absorbed. The effectiveness of this process depends on the sponge's material and the type of oil.

What is a Purple Tube Sponge?

This is from www.reefnews.com: This Purple Tube Sponge colony lives on a dead coralhead. The coral may have succombed to the algae and sponges that grew over the polyps and killed them. Now the skeleton of the coral supports a variety of sponges and algae. Sponges are colonies of thousands of individual cells. The cells work together, pumping water through the body of the sponge. The tall tube is in the shape of a "chimney." This chimney is an exhaust tube, where the water pumped by the sponge comes out. The sponge eats the plankton it filters out of the water as the water is pumped through the body of the sponge. Animals that eat sponges and algae help to keep a healthy balance on the reef. If there are too few of these animals, then the sponges and algae may take over. Examples of algae eaters are Parrotfishes, Sea Urchins, and Crabs. Examples of sponge eaters are Hawksbill Turtles and Loggerhead Turtles.
