Atlantic Goliath Grouper Fact File

? Size: Individuals can grow up to 2.5m long and weigh over 350kg

? Distribution: They can be found primarily in shallow tropical waters among coral and artificial reefs, including the Gulf of Mexico and Florida Keys in the United States, the Bahamas, most of the Caribbean, and most of the Brazilian coast

? Diet: Like most groupers, this species is an ambush predator and eats fairly large fishes and invertebrates and even small sharks

? Behaviour: Throughout most of the year, low numbers of Atlantic goliath groupers are observed in any one place. However, during reproduction they come together in groups of at least 100 individuals

? IUCN Status: Vulnerable. Scientists believe that destructive fishing practices have reduced the numbers of Atlantic goliath groupers by at least 80%. Reefs with large numbers of predators, like this species, are known to be healthier than reefs with no predators, so this species may represent an important part of the reef food web
