A lot of Sea Urchins in shallow water. I noticed that where there were Urchins, there was little to no kelp or algae. where there were no Urchins, the kelp was thick.

Sea urchins feed voraciously on kelp, as well as other types of Protists, small marine creatures, and detritus. Scientists compare the populations of kelp and sea urchins to estimate the health of an area.

the Sea Urchins are fished heavily in this area here, and I am noticing a large increase in kelp and algae around our wharves because of it.
