SeaWorld was a whale of an IPO, with great fanfare and penguins, but lately the aquatic entertainment company has been on rough seas. First, a CNN documentary, Blackfish, hampered the company, and more recently, underperforming on the market has been a bad look for SeaWorld. Now, a series of controversial murals are shaming away Shamu's partners -- can SeaWorld overcome a string of bad press and rebound on markets? Or, will a lingering investigation into its practices with killer whales sink investors? Already, some insiders are selling shares, and the company is looking to turn things around in the second half.
