Its large, thick, elongated body can grow to over 8 feet long (and up to 800 pounds), from rounded snout and small eyes, to short, fan-like tail fin.

Usually it is a mottled yellow-brown to gray with darker bard and spots, ideal for blending in to their rocky coral and muddy inshore habitat. Other names are Baden (Portuguese), campus (Portuguese), hernia gig ante (Italian), China (Spanish), group (Portuguese), gran morgue (Iranian), guava (Spanish), data (Japanese), harbor (Norwegian), havsabborre (Swedish), Tamara Vienna (Polish), Judaism (Norwegian), hero guava (Spanish), hero (French), orphan (Turkish), raitameriahven (Finnish), Sophos (Greek), scarring (Italian), tip (Palikir), Atari (Icelandic), and zackenbarsch (German).

Spear fishers find this fish easy to approach; hence in locations accessible to divers their numbers have declined. The large size, slow growth, low reproductive rate, and spawning behavior have made the goliathgrouper especially susceptible to overfishing.

The goliathgrouper is totally protected from harvest and is recognized as a “Critically Endangered” species by the World Conservation Union (IUCN). Furthermore, the IUCN concludes that the species has been “observed, estimated, inferred or suspected” of a reduction of at least 80% over the last 10 years or three generations.

Historical exploitation of goliathgrouper annual spawning aggregation sites greatly reduced the number of reproductive adults. Occurring in shallow, inshore waters to depths of 150 feet (46 m), the goliathgrouper prefers areas of rock, coral, and mud bottoms.

It is territorial near areas of refuge such as caves, wrecks, and ledges, displaying an open mouth and quivering body to intruders. Additional warning may be delivered in the form of the goliathgrouper ’s ability to produce a distinctly audible rumbling sound generated by the muscular contraction of the swim bladder.

The presence of a number of short weakly developed canine teeth is useful in distinguishing this species from other North Atlantic groupers. Photo © Don Maria Size, Age, and Growth The goliathgrouper is the largest grouper in the western Atlantic.

However, this specimen was sampled from a population of individuals depressed by fishing pressure and it is projected that goliathgrouper may live much longer, perhaps as much as 50 years. Photo © Don Maria Food Habits Goliath grouper feed largely on crustaceans (in particular spiny lobsters, shrimps and crabs), fishes (including stingrays and parrot fishes), octopus, and young sea turtles.

However, the significance of this finding is of diminished value when one considers that transitional individuals are known to be rare amongst confirmed species of protogynous hermaphrodites, such as the red grouper (Epimetheus Mario) and gag (Mycteroperca microbes). Photo courtesy National Marine Fisheries Service In support of the notion that the species is a protogynous hermaphrodite is the fact that the largest Goliath groupers are invariably male. Spawning occurs during the summer months of July, August, and September throughout the goliathgrouper ’s range and is strongly influenced by the lunar cycle.

Ship wrecks, rock ledges, and isolated patch reefs are preferred spawning habitat. In the 1980s these aggregations reached a low of less than 10 individuals per site as fishing pressure greatly impacted this species.

Since receiving legislative protection the spawning aggregations of goliathgrouper have risen to 20-40 individuals per location. These pelagic larvae transform into benthic juveniles at lengths of one inch (2.5 cm), around 25 or 26 days after hatching.

In an 1884 work, “The fishes of the Florida Keys,” David Starr Jordan proposed the inclusion of the goliathgrouper in Epimetheus (Bloch 1793) and this combination remains in use today. Of incidental note is the fact that various authors have incorrectly spelled the specific epithet “Tamara” as “tiara.” The genus name comes from the Greek epinephelos translated as cloudy.

A number of authors treat the name Promiscuous Tamara as valid taxonomy for the goliathgrouper. The Grouper family ranges from the small Cabrillo that are often caught when bait fishing on the rocks, to the larger Big- Eye, Yellow fin, Broom tail and finally the GoliathGrouper, which can grow to several hundred pounds.

Bases of the soft dorsal and anal fins are covered with scales and thick skin. While these massive spawning events are a blast because I get together with all my friends, historically it has been a dangerous time for us because it’s easy then for fishermen to catch us in big numbers.

We’re dedicated to working with indigenous communities, legislators, scientists and people like you to advocate for science-based solutions to protect this fragile ecosystem. It can come to measure up to 8.2 feet and weigh up to 680 pounds. It possesses a robust and elongated body, with a wide head in comparison to its small eyes.

Goliath grouper feed largely on crustaceans (in particular spiny lobsters, shrimps and crabs), fishes (including stingrays and parrot fishes), octopus, and young sea turtles. The goliathgrouper is found primarily in shallow tropical waters among coral and artificial reefs.

The rear half of the caudal peduncle of these small individuals is covered by another similar bar. The giant of the grouper family, the Goliath (formerly called Jewish) has brown or yellow mottling with small black spots on the head and fins, a large mouth with jawbones that extend well past its small eyes, and a rounded tail.

Recreational anglers are encouraged to use electronic charting equipment to plot the 20-fathom break by entering the established coordinates listed on … A number of authors treat the name Promiscuous Tamara as valid taxonomy for the goliathgrouper.

It is also found in the eastern Atlantic Ocean, from Senegal to Congo although rare in the Canary Islands. Since receiving legislative protection the spawning aggregations of goliathgrouper have risen to 20-40 individuals per location.

Furthermore, the IUCN concludes that the species has been “observed, estimated, inferred or suspected” of a reduction of at least 80% over the last 10 years or three generations. They were once so overfished in the southeastern United States, they were considered for listing under the Endangered Species Act.

Sabir had just caught a lesser amber jack with his spearfish gun, he told Grind TV, when he noticed the large grouper eyeing him and closing the distance in between them.

However, the significance of this finding is of diminished value when one considers that transitional individuals are known to be rare amongst confirmed species of protogynous hermaphrodites, such as the red grouper (Epimetheus Mario) and gag (Mycteroperca microbes).
