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:
- Spongilla is typically yellowish brown in colour, with multiple small individuals sharing a common flat base.
- Spongilla is a common freshwater sponge that lives in lakes and ponds as colonies attached to sticks or wood pieces.
- Every Spongilla individual has multiple Ostia and one osculum (which can be one for one individual or one for many individuals).
- Spongilla has a rhagon canal system and a skeleton made up of spongin fibres with silicious monaxon spicules.
- 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.
