Fig. 6. Bryozoa (coral patches) 



(fig. 6). When an adult Barnacle falls off the 

 hull it generally leaves behind a circular patch 

 or base plate. This may resemble a coral patch. 

 The base plate of the Barnacle is marked by 

 lines, whereas the coral patch is distinctly 

 granular in appearance. The flat encrusting type 

 of Bryozoa is freq^uently hard and calcareous, 

 whereas the branching type is generally soft and 

 flexible.
