Groups of Cassiopeia jellyfish are commonly found upside-down on the seafloor, with their tentacles extending upwards into the water column above.  These jellyfish, like corals, contain algae in their tentacles and turn upside-down to expose the algae to sunlight. Sometimes, however, they are seen pulsing to move, as shown in this photo taken by CSA staff offshore Key West. 

CSA Monitors Nearshore Hardbottom off the Treasure Coast

This video provides a compilation of CSA marine biologists conducting underwater monitoring of nearshore hardbottom resources off the east coast of Florida for several beach nourishment projects. The Florida Department of Environmental Protection requires that nearshore hardbottom monitoring be conducted before, during, and (for a certain number of years) following a beach nourishment project. As part of these monitoring efforts, CSA marine biologists assess percent cover of marine flora and fauna within quadrats, measure sediment depth on hardbottom, and map the edges of hardbottom features using a GPS buoy. The video also shows some of the various marine life comprising the nearshore hardbottom biological community, including algae, sponges, urchins, jellyfish, and sharks.
