Predators. To date, the only known natural predator of the blue whale is the orca. Otherwise, this gentle giant has little to fear in the ocean other than the dangers posed by human activity.CarnivorousBlue whale / Trophic level
The blue whale is a carnivore, to be sure, but not a top predator in the sense of hunting and eating large animals. Instead, it gobbles shrimplike creatures—which themselves eat mainly phytoplankton: those icroscopic photosynthesizers that make up the vast bulk of ocean plant biomass.Nearly all whales and dolphins are considered uniparous. This means they typically only give birth to one baby at a time. While considered extremely rare, cetaceans in the whale and dolphin species can have twins but this has been recorded in very low numbers, occurring in less than 1% of all births.
How deep do blue whales live : Blue whales usually feed at depths less than 100 m (328 ft) and no more than 152 m (500 ft). They lunge at dense clouds or patches of krill, expanding their throat grooves to take in as much as 64,252 l (17,000 gal) of food and water in a single mouthful.
What eats a killer whale
Orcas are apex predators, at the top of the food chain. No animals hunt orcas (except for humans). Killer whales feed on many different types of prey, including fish, seals, sea birds and squid.
What fights blue whales : The killer whale is one of the only predators of the blue whale.

Blue whales are often referred to as the “gentle giants” of the ocean, and for good reason. Despite their massive size, they are known for their calm and docile behavior. They are curious creatures and have been observed approaching boats and interacting with humans in a friendly manner. Therefore, Blue Whales have been categorized by IUCN as “endangered” species. Blue Whales are filter feeders and do not eat humans; instead, they feed upon krill.

Before whaling, there may have been as many as 250,000 blue whales, but today, it is one of the world's rarest species, with a population of just 10,000-25,000. Sadly, blue whales face a multitude of threats from human interference. However, it's not too late to change their fate.Scientists have discovered that by counting the layers of a deceased whale's waxlike earplugs, they can get a close estimate of the animal's age. The oldest blue whale found using this method was determined to be around 110 years old. Average lifespan is estimated at around 80 to 90 years. před 6 dny
Blue whales are not aggressive towards humans and have never been known to attack or harm humans intentionally. In fact, there have been numerous accounts of blue whales saving humans from shark attacks by using their massive bodies to block the sharks.
Do killer whales eat blue whales : Orcas can hunt and kill blue whales
The attacks were recorded by marine scientists from Cetrec WA (Cetacean Research). The report includes details of how the killer whales swam inside the mouth of the enormous whales to eat their nutritionally rich tongue just before they died.
What are killer whales afraid of : Selbmann says that in the majority of the interactions documented around Iceland, killer whales seem to avoid pilot whales. Occasionally things will get heated and the pilot whales will chase the killer whales at high speeds, with both species porpoising out of the water.
Can any animal beat a blue whale
Orcas take down a blue whale, proving they're the apex predators of the ocean. While killer whales are known to attack blue whales, John Totterdell and his colleagues are the first to ever document a successful takedown. And they've done it more than once, publishing their findings in the journal Marine Mammal Science. Whales basically have two enemies: Orcas (killer whales, which in fact are not whales, but dolphins) and human beings. Only one type of Orca, the transient orca, is known to attack whales and other marine mammals. Transients Orcas are sometimes referred to as "wolves of the sea" as they will hunt in packs.Because of their intelligence and social nature, orca whales are unlikely to attack humans out of aggression or hostility. In fact, there have been numerous instances of orca whales coming to the aid of humans who were in danger, such as when a group of orca whales helped a diver escape from a shark attack.
Has a blue whale ever hurt a human : Blue whales are not aggressive towards humans and have never been known to attack or harm humans intentionally. In fact, there have been numerous accounts of blue whales saving humans from shark attacks by using their massive bodies to block the sharks.
