General Biology Additional InformationOn collection all pores become invisible due to contraction of the colony, and the appearance changes considerably. 3mm thick x 10mm across as individual, large size from colonial mats up to 1m in size. They have the ability to attach tenaciously to substrates but the tunic is flaccid and tears easily. If even a small bit adheres to any organisms that are transported, it can rapidly colonize a new substrate and may already be in reproductive mode
