Botryllus planus
Taxonomic Group: Tunicates

Overview:

Botryllus planus is a colonial tunicate which can vary in color, ranging from being completely orange (as seen in the picture) to having zooids that are dark purple, purplish brown or black, with a white, pale green or golden yellow area surrounding the branchial opening of each zooid. It is native to the warm waters of the western Atlantic, from North Carolina, Bermuda, Panama, Curaçao, Colombia, Venezuela and Brazil. In North America, there is one record of this species from Chincoteague, Virginia, in 1994, but information on its establishment here is unknown, suggesting that it was a failed invasion. Throughout its range, B. planus can be found on both man-made and natural substrates, including floating docks, pilings, mangroves and rocky reefs. No impacts have been reported from introduced populations.

*Outside of its native range, this species is not currently established in North American waters.
