Description

I found a few examples of what I think are Metandrocarpa dura or Fused Orange Social Ascidians, living on the side of the dock at the marina, including this 5" orange one. The other was a darker, brighter orange. There were also what I think were Botryllus schlosseri or Harbor Star Ascidians in the same area.

I found a few examples of what I think are Metandrocarpa dura or Fused Orange Social Ascidians, living on the side of the dock at the marina, including this 3" bright orange one on the right. There were also what I think were Botryllus schlosseri or Harbor Star Ascidians in the same area. I'm not sure what is on the left, the beige-yellow one that looks like a brain.

I believe this may be Botryllus schlosseri or Harbor Star Ascidian, found hanging onto the edge of the dock at the marina. I'd never seen any Botryllus schlosseri until today, so I'm posting a few examples, hoping someone will do a positive ID. Here are two photos with different colors. Most of the ones I found were bright orange, the color of the California Poppy.

I believe this may be Botryllus schlosseri or Harbor Star Ascidian, found hanging onto a thick rope at the edge of the dock at the marina. I pulled the rope out of the water for a quick photo. I'd never seen any Botryllus schlosseri until today, so I'm posting a few examples, hoping someone will do a positive ID.

I believe this may be Botryllus schlosseri or Harbor Star Ascidian, found growing on mussels that were hanging onto the edge of the dock at the marina. I'd never seen any Botryllus schlosseri until today, so I'm posting a few examples, hoping someone will do a positive ID. Each ascidian was about 1" across, and most were this bright orange.

I believe these may be two colors here of Botryllus schlosseri or Harbor Star Ascidian, the orange one and the black and white. They were hanging onto the edge of the dock at the marina, and I'd never seen any Botryllus schlosseri until today, so I'm posting a few examples, hoping someone will do a positive ID.

Description from Wikipedia

Ascidiacea (commonly known as the ascidians or sea squirts) is a class in the Tunicata subphylum of sac-like marine invertebrate filter feeders. Ascidians are characterized by a tough outer "tunic" made of the polysaccharide tunicin, as compared to other tunicates which are less rigid.

No range data available.
