Note
At 0935 on November 30, 1978, a male and female roughtail stingray Dasyatis centroura were observed for a period of 10 minutes in an apparent courtship or mating ritual. This observation, using the JOHNSON-SEA-L1NK research submersible (J-S-L1, Dive Number 615), took place near the base of a deep-water, Oculina varicosa coral bank (Reed, 1980) 27 km east of Ft. Pierce, Florida at 27° 32. 8'N, 79° 58.8'W and at a depth of 80 m. The area was a flat sand bottom 20-30 m from the base of the 17 m high Oculina coral bank. A few pieces of limestone with Oculina rubble protruded through the green silty-sand, and patches of the gorgonian Titanideum frauenfeldii and the antipatharian Cirrhipathes desbonii covered the bottom.
