There is no new growth of other seaweeds, as opposed to that seen on the F2 East Transect – 2013 video. Invertebrates are common, especially truncate softshell clams (Mya truncata). Many of the rocks that used to be covered by seaweeds have fan hydroids growing on them (0:32, 1:01 seconds). The yellow blotches seen on rocks are encrusting bryozoans (0:25 seconds).
