Common name: Light-bulb Tunicates

Clavelina, commonly known as Light-bulb Tunicates, are a genus of ascidians belonging to the family Clavelinidae. These fascinating marine invertebrates are characterized by their translucent, gelatinous bodies that often resemble small light bulbs, hence their common name. They are sessile filter feeders, meaning they attach themselves to substrates such as rocks, coral reefs, or artificial structures in the ocean and feed by filtering plankton and other small particles from the water.

Clavelina species are often found in shallow, warm waters and can be seen in clusters, forming visually striking colonies that sway gently with the ocean currents. Their vibrant colors, which can range from clear to shades of blue, purple, and even yellow, make them an attractive addition to marine aquariums. However, they require specific conditions to thrive, including stable water parameters, adequate flow to facilitate feeding, and the absence of aggressive tank mates that might damage their delicate bodies.

From a scientific perspective, Clavelina is of interest due to its simple body structure and regenerative capabilities. Studying these organisms can provide insights into developmental biology and processes. For hobbyists, maintaining Clavelina in an aquarium setting can be challenging but rewarding, as they contribute to the biodiversity and aesthetic appeal of the tank. It is important to ensure that the aquarium environment mimics their natural habitat as closely as possible to support their health and longevity.
