Sea Squirts are lifejackets and swim assist vests designed to look like different fish. Designs include Killa Whale, Clown Fish, White Shark, Angel Fish, Blue Dolphin and Pink Dolphin. The jackets and vests actually have a flexible fin on the back. "Our mantra is, 'Fun follows function.' ... Our products have been designed in a way that kids want to wear them and aren't wearing them because they have to," Opa Cove President and CEO Richard Barbis told TDmonthly.
