Battery Park City Cove Video
In this video, a piling is surveyed in the South Cove of Battery Park. In the opening moments there is a sponge in the genus Microciona. The camera pans down showing blue mussels (Mytilus edulis) covering the piling. On the camera’s way up the piling (at 29 seconds in), a quick flash of yellow can be seen. This is a Spotfin Butterflyfish (Chaetodon ocellatus). This fish is rare in the Hudson River and can only be found in the summer and fall. Most Spotfins are pelagic strays, carried up north by the Gulf Stream currents from the tropics. This fish’s usual distribution is in the western Atlantic Ocean from Brazil to North Carolina. Higher up on the piling, four Cunner (Tautogolabrus adspersus) are swimming together. These fish grow up to 12 inches and often swim in small groups around piling and rock structure. Here they are swimming among the blue mussels and an unidentified species of white algae. The final footage in this clip shows a healthy colony of the blue mussels, a filter feeding bi-valve common to New York waters.
