Some tuna species (such as yellowfin tuna and skipjack tuna but not albacore tuna) associate with dolphins in the ocean. This helps themto avoid being eaten by sharks, which are one of their predators. Sharks are strongly attracted to tuna fish, even if the tuna fish are not injured or bleeding. However, examination of the contents of the stomachs of various sharks indicates that tuna fish have evolved to swim too fast for sharks to catch up to them and end up being eatenby sharks only occasionally.
Other predators of tuna fish include orcas (killer whales), false killer whales, pilot whales, bottlenose whales, bottlenose dolphins, and marlins but the giant, filter-feeding whales and sharks can only eat small fish, which are usually not small tuna fish. Also, sperm whales occasionally eat tuna fish but like sharks, they tend to be too slow to catch up to tuna fish in most situations.
However, because of man's strong appetite for tuna fish, humans are the only real possible threat to the sustainability of tuna fishing.
Interestingly, blue sharks can swim as fast as tuna fish. Also, seals can swim faster than Great White Sharks but end up being frequently eaten by great white sharks because great white sharks wait patiently and then ambush them from deep below by surprise. All predatory sharks like to pretend that they are just harmless filter feeders when a large school of fish approaches them.
Yes, tuna is a predator, and near the top of the chain.

A predator-prey relationship near where I live is dolphins-tuna-sardines. Dolphins are predators that hunt and eat tuna, who are the prey of dolphins. The tuna are also predators, but they hunt and eat sardines, who are the prey of tuna. So dolphins know to look for tuna where they see sardines, but they do not prefer to eat the sardines.
the yellowfin tuna's biggest predator is a monkey because they lick there bum holes clean
Crabs, Angler Fish, Tuna, Rays, and Penguins.
Seagulls, Some types of Tuna, rats.
I'm not 100% sure but my best guess is yes.
shark and tuna can be considered as predator and prey that shark feeds on other organism and tuna becomes a prey to the sharkoctopus and a crab. the octopus is the predator who eats the prey, the crab
The predators of the blue tang are Tuna, Bar jack, Tiger grouper, and other large carnivorous fishes.
No. The largest Predatory fish is the Whale Shark. It is a filter feeder; it's diet consists primarily of plankton and krill.
Some types of Tuna like 'Little Tuny' and 'Bonito' are used as bait. Larger type of Tuna usually kept for either selling or eating. Blue Fin Tuna, I think are the largest type of Tuna are over fished. They are the ones that sell for thousands of US dollars in Japan. When the Blue Fin are smaller, I am sure they get eaten by predatory fish too. If you like sushi or sashimi, try to avoid eating tuna because it is most likely Blue Fin tuna. The Tuna that one buys in the can is usually Albacore Tuna, which is monitored and not over fished. Lastly, Tuna is prey to humans.
Those of any significant quantity are: CHON (carbon, hydrogen, oxygen and nitrogen)--same as for any other organism. There are trace elements and there is the potential for mercury to be present because the tuna is an apex predator.
There are more than you think. The most common are the Halibut, Yellow-tail Tuna, all sharks and salmon. Dolphins in a feeding frenzy are known to devour schools of the Anchovy . Also Pelicans and the Tern. But their biggest predator is the human being. We comsume many tons of Anchovy.
