Common name: green finger sponge
General information
The Convoluted Barrel Sponge, Iotrochota birotulata, is a species of sponge found in the Caribbean Sea. It is known for its distinctive barrel-like shape and convoluted, or folded, surface which gives it a brain-like appearance. This sponge can vary in color from dark brown to greenish-yellow and has a rough, leathery texture.

Care
In the home aquarium, Iotrochota birotulata requires a moderate to high flow of water to mimic its natural environment and facilitate feeding. It is a filter feeder, extracting nutrients from the water column. Stable water quality and parameters are crucial for the health of this sponge, as it can be sensitive to changes in its environment.
Reproduction
Sponges like Iotrochota birotulata reproduce both sexually and asexually. Sexual reproduction involves the release of sperm into the water column, which then fertilizes eggs in other sponges. Asexually, they can reproduce by budding, where a part of the sponge breaks off and grows into a new individual.
Symbiosis
While not hosting a wide range of symbiotic relationships like some corals or anemones, sponges such as Iotrochota birotulata do play a role in the ecosystem by providing microhabitats for various small organisms and contributing to the overall health of the reef system.
Habitat
Iotrochota birotulata is typically found in shallow to mid-depth waters of the Caribbean Sea, often attached to hard substrates in areas with strong currents. It is an important member of the reef community, contributing to the structural complexity and biodiversity of the habitat.
