Major sessile organisms and plants on test panels. 



The biological growth, such as bryozoans, hydroids, and algae, could 

 be scraped off the panels without too much difficulty; however, some small 

 structures of the animals and plants would remain firmly attached to the 

 panels. Mussel shells and the calcareous tubes of tubeworms were slightly 

 more difficult to remove from the surfaces of the panels. The animal growths 

 most difficult to remove were barnacle shells. The barnacle shells of live or 

 dead animals could be removed only by breaking the shells off the panels with
