Glass sponges
Glass sponges are considered the class Hexactinellida.
The three classes of sponge skeletons are siliceous or glass sponges (Class Hexactinellida), calcareous sponges (Class Calcarea), and sponges with a fibrous protein skeleton (Class Demospongiae). Each class has unique structural characteristics that support the sponge's body.
Hexactinellida, Calcarea, Demospongiae, andSclerospongiaeTechnically, however, the Sclerospongiae are not considered sponges. They are very similar, but they are not the same. Like bats and birds who have both evolved the ability to fly but are not the same types of animals, Slerospongiae have evolved and became very similar to sponges, but they are not sponges.
no
There are thousands of different types of sponges, so there's not enough room to list them all. Here's a great website showing several hundred different sponges found in the Caribbean so you can get some idea of the different groups they fall into.
get lots of sponges,towels,soap,and water.rubit on glass.and there you have it. you have shiny glass.
The primary chemical component of glass sponges is silica, which is primarily in the form of silicon dioxide (SiO2). This silica forms intricate skeletal structures, giving glass sponges their characteristic glass-like appearance. Additionally, their skeletons may contain organic materials and spongin, but silica is the predominant structural element.
it filters out bacteria from the water
sponges are use in washing plates,glass of water.some sponges are in/on salted water on the ocean floor.
sponges use toxins to repel would be predators
Glass sponges generally live at water depths ranging from 1480 to 3000 ft. (450 to 900 meters).However, there is one species of glass sponge Oopsacas Minuta which has been found at much shallower depths, and there have been other glass sponge species which have been found at much deeper depths.
