Live Golden Star Tunicate (Botryllus schlosseri)
Please note this is a live marine specimen.

The Golden Star Tunicate (Botryllus schlosseri) is a colonial ascidian commonly found along Maine’s rocky shores, attached to pilings, floats, kelp, and tidepool surfaces. Recognized for its distinctive star-shaped zooid pattern, this fascinating invertebrate displays shades of peach, brown, black, and white — sometimes with yellow centers that give the colony its “golden star” appearance. These filter-feeding organisms play an important ecological role in coastal systems and make striking additions to aquariums and marine research displays. Sustainably hand-collected from the Gulf of Maine, each specimen is shipped live for classroom, aquarium, or laboratory use.

An assortment of tunicates.

Tidepool Tim says,  "Golden star may be an invasive species and detrimental to some other organisms that it outcompetes, but it is a beautiful colonial tunicate.  The zooids resemble tiny flowers that pulse with water flow.  We find most colonies of this tunicate on docks & floats around our local shipping port in Eastport.  It's easy to imagine that some large ship or even a working barge may have brought the species here to our waters.  These tunicates spread rapidly across the seafloor and can out-compete barnacles, mussels, snails, and some algal species.  They are hermaphrodites.  They filter their food from the water with individual siphons, but excrete through a central pore. This is what gives them the 'star' look. Besides the very pretty black and white colonies, they can be yellow, orange, & red globby-looking masses.”
