Common name: Sponge

General information

Hyattella intestinalis, commonly known as the Intestinal Sponge, is a species of sponge found in marine environments. This sponge is characterized by its tube-like structure and brownish color, which can blend well with its surroundings. It is a filter feeder, meaning it feeds by straining suspended matter and food particles from water, typically by passing the water over a complex system of pores and channels.

Care

The Intestinal Sponge requires a well-established aquarium with stable water conditions. It thrives in areas with moderate to strong water flow, which facilitates its feeding process. Adequate lighting is also necessary, although direct intense light should be avoided as it can promote the growth of algae on the sponge's surface. It's important to note that sponges should never be exposed to air, as trapped air bubbles can be fatal.

Reproduction

Sponges like Hyattella intestinalis can reproduce both sexually and asexually. In the aquarium, asexual reproduction is more common, where a piece of the sponge breaks off and attaches to a substrate to grow into a new individual. Sexual reproduction involves the release of sperm into the water column, which then fertilizes eggs in other sponges.

Symbiosis

While not known for any specific symbiotic relationships, sponges in general play a crucial role in the marine ecosystem. They provide microhabitats for a variety of small organisms and contribute to the cycling of nutrients.

Habitat

Hyattella intestinalis is typically found in reef environments, often growing on rocks or other hard substrates. It is distributed in various parts of the Indo-Pacific region.
