Description
The Giant Trevally (Caranx ignobilis), also known as Ulua, barrier trevally, giant kingfish, and lowly trevally, are fish that belong to the family Carangiformes and inhabit the warm waters of the Pacific and Indian ocean. They are popular gamefish and not edible for the possibility of ciguatera poisoning.
These animals are identified by their strong tail scutes and steep head profiles. The Giant Trevally prefers solitary life and only congregates in schools to feed or reproduce. Juveniles are silvery-grey while mature male Giant Trevally have black colorations and spot an intimidating stare. They love to follow sharks and seals to feed on forgotten prey.

What do saltwater fish eat?
Saltwater fish can carry carnivore, herbivore, or omnivore diets. Herbivore saltwater fish consume both microalgae and macroalgae as well as seagrasses. A carnivore’s diet typically consists of shrimp, plankton, and tiny crustaceans. Some carnivores may eat worms, clams, and parasites. Most carnivore saltwater fish will not eat algae even if they are starving.
Why can’t saltwater fish live in freshwater?
Saltwater fish are not able to live in freshwater because their bodies are concentrated from salt solution. Saltwater fish would not be able to osmoregulate correctly in freshwater. Freshwater would flow into their body up to the point where all cells can accumulate water causing them to bloat and die.
How do you acclimate saltwater fish?
Saltwater fish can be acclimated in a couple of ways. This can be done by modifying the water’s salinity, altering the pH of the water, and using the drip method or the floating method. It is important to acclimate saltwater fish because changes in salinity, water temperature, and water chemistry can cause stresses that shock the fish to death.

What is the largest bony fish?
The largest bony fish is a female Mola alexandrine that was caught on the Japanese coast of Kamogwa, Chiba in 1996. The fish has a total weight of 2,300 kilograms and a height of 2.72 meters. It is currently the heaviest bony fish ever recorded in history.
When did bony fish first appear?
Bony fish first appeared between 530 to 410 million years ago during the Cambrian explosion. The first bony fish did not have jaws and had a primitive spinal column. It is believed that the first bony fish appeared along with the placoderms, who were the first jawed fish that evolved from their gill arches.
How do Osteichthyes reproduce?
Osteichthyes mostly reproduce through the sperm and eggs that are developed by male and female Osteichthyes. Some Osteichthyes are hermaphrodites and can produce both sperm and eggs. Male and female Osteichthyes may at times look similar or different due to their size, color, head characteristics, and overall body shape.

What do fish eat?
The diet of fish is very diverse as the number of fish species is very large. Some fish are carnivores, while other species of fish are herbivores or omnivores. Fish generally eat small organisms, algae, and sometimes can even eat other fish. The food that fish eat depends on their species, size, and environment.
How long do fish live?
The lifespan of a fish usually depends on the species. A fish may live anywhere between a year to 200 years – it all depends on the species of fish. The lifespan of a fish typically depends on their size, species, and whether they live in the wild or captivity.
How do fish sleep?
Fish do not sleep in the same form and manner that land mammals sleep. Fish sleep by reducing their activity and metabolism while remaining alert to any potential danger. While sleeping some fish float in place, in a secure spot within the mud, or find a nest. During sleep, fish perform restorative functions.

What do marine animals need to survive?
Factors that marine animals need to survive include bioluminescence which is when animals make their own light and helps them communicate and scare predators. Constant light, pressure, temperature, and food are factors needed to remain stable and help marine animals evolve to survive. Marine animals that live within the deep sea can withstand the cold.
Why do we need to protect marine life?
Humans need to protect marine life because our actions and lifestyles have a direct impact on the ocean. We need to protect marine life and provide a safe and healthy environment that is not impacted by overfishing, climate change, pollution, habitat destruction, invasive species, and other forms of human exploitation.
What is the most common animal in the ocean?
The most common animal in the ocean is the bristlemouth which is a vertebrate, an animal with a backbone. The bristlemouth is a tiny fish that can glow in the dark and has fangs that resemble needles. Bristlemouths are part of the 1 million species of animals that live in the ocean.

Why do animals live in coral reefs?
Animals live in coral reefs because this habitat provides warm water as well as an abundant food supply. The physical form of coral reefs has a lot of nooks and crannies that help fish hide from potential predators. Many small tropical fish typically live within coral reefs.
Can animals harm coral reefs?
Yes, animals can harm coral reefs if the predator populations can become too high, and thus corals can become devastated. Coral reefs can also be harmed through overheating causing them to dry out and overheat or become physiologically stressed which can lead to bleaching or death.
Is coral an animal or a plant?
A coral is an animal because they do not make its own food as a plant does. Corals have small tentacle-like arms that they use to capture their food from the water. Corals go through a unique process called symbiosis which benefits both animals and plant life.

How do animals adapt to the coast?
Animals adapt to the coast by adjusting to living in salty water as well as being able to withstand being covered or uncovered by the tide. Further coastal adaptations also include being able to hide or escape quickly from predators, finding food, and staying in a safe place as the tides move.
Why are coasts important for wildlife?
Coasts are important for wildlife because they serve as nesting grounds for species of sea turtles as well as are habitats for animals like beach mice. Coasts are also important foraging areas for migratory shorebirds. Coasts are important as they are used in cohesion by all species of animals.
How does coastal erosion affect animals?
Coastal erosion affects animals and humans as it causes sea levels to rise, flooding, as well as stronger waves. Coastal erosion also causes the gradual loss of land that is important to many animals. Coastal erosion is when a portion of land is lost within a shoreline by either natural events or manmade decisions.

How do animals survive in estuaries?
Animals survive in estuaries by adapting to the harsh conditions of their habitat. Estuaries either have salt water or fresh water. Animals survive by adapting to live in the different types of conditions and remaining in the regions of the estuaries where they are most comfortable and have consistency.
Why do fish lay eggs in estuaries?
Fish lay eggs in estuaries because these habitats offer a great amount of food availability for the development of young fish while also providing protection from predators. Estuaries are often used as breeding grounds by many species of fish due to these factors and are considered highly valuable.
Why are estuaries important for birds?
Estuaries are important for birds because estuaries offer a mix of nutrients from both the land and sea, creating a rich ecosystem. Since estuaries house numerous species of fish, they also create a food source for birds. Birds also use the beaches next to estuaries for feeding, resting, and breeding.
