Common name: Inkspot Sea Squirt

General information

The Inkspot Sea Squirt, Polycarpa pigmentata, is a fascinating invertebrate that adds a unique touch to any reef aquarium. This species is part of the Ascidiacea class, commonly known as ascidians or sea squirts. They are sessile animals that attach themselves to hard substrates in the marine environment. The Inkspot Sea Squirt is particularly noted for its striking appearance, characterized by a translucent body with conspicuous dark spots, which is the origin of its common name.

Care

Polycarpa pigmentata requires a stable aquarium with good water quality. They are filter feeders, extracting plankton and other nutrients from the water column. It is essential to maintain a steady flow of water through their siphons to ensure they receive adequate nutrition. They do not require additional feeding if the tank has a sufficient amount of microfauna, but in a less established tank, they may benefit from targeted feeding of phytoplankton or fine particulate foods.

Reproduction

Sea squirts are known for their unique reproductive strategies. Polycarpa pigmentata can reproduce both sexually and asexually. Sexual reproduction involves the release of sperm and eggs into the water column, where fertilization occurs. Asexually, they can bud from the parent organism, creating clones that contribute to the growth of the colony.

Symbiosis

While Polycarpa pigmentata does not have the same level of symbiotic relationships as some other marine organisms, it does contribute to the overall health of the reef ecosystem. By filtering water, sea squirts play a role in maintaining water clarity and quality, which benefits all inhabitants of the reef aquarium.

Habitat

The natural habitat of the Inkspot Sea Squirt includes coral reefs and rocky substrates in the Indo-Pacific region. They are typically found at various depths, often in areas with moderate to strong water currents which facilitate their filter-feeding lifestyle.
