Structure of Spongilla (Explained with Diagram)

In this article we will discuss about the structure of spongilla with the help of a spongilla diagram.

What is Spongilla?

Spongilla is a freshwater sponge genus. They can be found clinging to rocks, sticks, and plants. They have a dormant stage known as gemmules that allows them to withstand harsh weather conditions. These sponges have a soft texture and a thin dermal layer. Spicules on the dermal layer provide structural support and protection.

Structure of Spongilla

Let’s learn some points about the Spongilla structure from the following section:

  1. Spongilla is typically yellowish brown in colour, with multiple small individuals sharing a common flat base.
  2. Spongilla is a common freshwater sponge that lives in lakes and ponds as colonies attached to sticks or wood pieces.
  3. Every Spongilla individual has multiple Ostia and one osculum (which can be one for one individual or one for many individuals).
  4. Spongilla has a rhagon canal system and a skeleton made up of spongin fibres with silicious monaxon spicules.
  5. Because of their delicate structure, sponges grow as encrusting or branching masses, and the algae that thrives on them causes them to appear greenish at times.
