The giant trevally is one of the most important apex predators in its habitats, both as adults on reefs and as juveniles in estuaries. [34] Observations in relatively untouched waters of the northwestern Hawaiian Islands showed the giant trevally was of high ecological importance, constituting 71% of the apex predator biomass , and was the ...
The bigeye trevally has 21 to 25 gill rakers and 25 vertebrae. [7] The bigeye trevally shows a change in colour as it ages, changing both overall colour and body patterns. Juveniles are a silvery yellow to silvery brown in colour, and possess five to six dark vertical bands on their sides, [8] from which the specific epithet sexfasciatus arose.
The dogtooth tuna is one of the apex non-pelagic predators in its environment, sharing that position with giant trevally, Napoleon wrasse, and large groupers, as well as large sharks such as reef, bull and tiger sharks. [citation needed]
The bluefin trevally is a large fish, growing to a maximum known length of 117 cm and a weight of 43.5 kg, [2] however it is rare at lengths greater than 80 cm. [8] It is similar in shape to a number of other large jacks and trevallies, having an oblong, compressed body with the dorsal profile slightly more convex than the ventral profile, particularly anteriorly.
Golden trevally often follow large fish such as this giant grouper. The golden trevally is found either as a solitary individual or in small schools as an adult. [7] Juveniles tend to form larger schools which tend to congregate and follow ( or "pilot") larger fish such as groupers, sharks, [15] and even jellyfish. [20]
“They are the only group of birds that achieved the role of terrestrial apex predators, evolving species that basically conquered South America during the Miocene (about 23.03 million to 5.33 ...
Giant trevally are great gamefish found in Indo-Pacific tropical waters. They are powerful apex predators in most of their habitats, hunting both individually and in schools. Cutlassfishes are a group of about 40 species belonging to the family Trichiuridae. They are ocean fish which regularly stray into coastal waters around the world.
