This film is about Goliath Groupers, their biology, ecology and threats. It is a history about the huge importance they have for a balanced environment where they live. Throughout a documental perspective, our “spokesfish”, a BOFFF (big old fat fertile female) Goliath Grouper, presents the sea bottom to a documentarian diver. She swims over the Brazilian coast where Goliath Groupers live, presenting other threatened species, ecosystems and revealing peculiarities of their lives. It advocates that protecting a threatened species is a form to protect huge coastal marine environments.
