Common name: Sea Squirts
Ascidiacea, commonly known as sea squirts, are fascinating marine invertebrates belonging to the subphylum Tunicata. They are named for their ability to squirt water when disturbed, a defensive mechanism that surprises potential predators. Sea squirts are sessile animals, meaning they are permanently attached to a substrate, such as rocks, shells, or the hulls of ships. This sedentary lifestyle makes them a unique addition to marine aquariums, particularly invertebrate-focused or biotope tanks.
Sea squirts have a sac-like body structure with two siphons: an incurrent and an excurrent siphon. They draw water in through the incurrent siphon, filter out plankton and other small particles for food, and expel the filtered water through the excurrent siphon. This filter-feeding process is not only interesting to observe but also beneficial to the aquarium environment as it helps maintain water quality by removing excess nutrients.
Aesthetically, sea squirts can add a splash of color and diversity to an aquarium. They come in various shapes, sizes, and vibrant colors, ranging from bright yellows and oranges to deep purples and blues. However, their care requires careful attention to water quality and flow, as they are sensitive to changes in their environment. It's essential to provide a stable environment with adequate flow to ensure their health and longevity.
While sea squirts are not commonly kept in home aquariums due to their specific care requirements, they can be an intriguing subject for advanced hobbyists interested in marine biology and ecosystem dynamics. Their presence can also encourage the growth of beneficial microfauna, contributing to the overall biodiversity of the tank.
