Lionfish became established in the Florida Keys in 2009. The fish has numerous head spines and the dorsal and anal fins have strong, venomous spines. Means of Introduction: At least six lionfish were liberated into Biscayne Bay when a beach-side aquarium broke during Hurricane Andrew in August 1992 (Courtenay 1995). The most probable explanation for the arrival of the lionfish population in the Atlantic Ocean is via the aquarium trade (Whitfield et al. 2002; Semmens et al. 2004). This picture was taken at Crosscurrent Barge in Palm Beach County in 60 feet of water.
