Question

what is the subphylum of euplectella?

Answer 1

"Euplectella is a genus of Glass sponge which includes the well-known Venus' flower basket, E. aspergillum. "

Answer 2

The body structure of these animals is a thin-walled, cylindrical, vase-shaped tube with a large central atrium. The body is composed entirely of silica in the form of 6-pointed siliceous spicules, which is why they are commonly known as glass sponges. The spicules are composed of 3 perpendicular rays giving them 6 points. Spicules are microscopic, pin-like structures within the sponge’s tissues that provide structural support for the sponge. It is the combination of spicule forms within a sponge’s tissues that helps identify the species.
