EXPEDITIONS Flag Reports   FLAG 89 The Sleeping Sharks of Juno Ledge January 22—February 21, 2005 By Pierce Hoover FN'02 Expedition Members: Pierce Hoover—Expedition Coordinator MV Animal House—Expedition Platform Walt Stearns—Search Team Leader Dr. Sameul Gruber—Research Team Leader Zeagle Systems, Aquaturis—Equipment Providers Introduction The lemon shark is one of 39 shark species protected by the US Government through the Department of Commerce. Although it is one of the best-studied sharks, very little nothing is known about the adult phase of its life. Thus, any opportunity to investigate mature lemon sharks will likely produce new information to complete our understanding of the life history of an endangered shark species. On January 2001 divers Walt Stearns and Pierce Hoover located a large, mixed aggregation of lemon sharks in 25 m of water approximately 8 km east of Jupiter Inlet, Florida. A year later a similar aggregation was reported in the same area. Documentation of this aggregation was subsequently forwarded to Dr. Samuel Gruber, of the University of Miami’s Rosenstiel School of Marine and Atmospheric Science. Gruber, who has studied lemon sharks for more than 40 years, and is widely regarded as one of the world’s leading authorities on the subject, immediately recognized the significance of the phenomenon.
