Grantiidae [Grantiidae]

Description

Grantiidae is a family of calcareous sponges found in marine environments. These sponges are characterized by their asconoid type of canal system, which is the simplest form among sponges, consisting of a single internal cavity through which water flows. Members of the Grantiidae family are known for their tube-like or vase-like shapes, and they possess a skeleton made of calcium carbonate spicules, which can be either monoaxon (single axis) or triaxon (three axes). These sponges are typically small, sessile, and filter feeders, capturing plankton and other small particles from the water. They are found in a variety of marine habitats from shallow to deep waters and often adhere to solid substrates like rocks or coral reefs. The Grantiidae family contributes to the biodiversity and ecological balance of marine ecosystems by participating in the nutrient cycling and providing habitat for microorganisms.
