Do humpback whales rescue seals from orca attacks?
Humpback whales rescue seals from orca attacks. The photo is extraordinary.

Why do killer whales attack seals?

Does this photo show a seal photographed with a beluga whale?
In June 2017, an image purporting to show a sweet moment between a seal and a beluga whale went viral on social media: Although the image was often shared along with a description calling it an “incredible shot”, thereby insinuating that it is a genuine photograph, it does not show an actual moment.
What do whales and seals have in common?
Thick layers of blubber beneath the skin of both whales and seals act as a food reserve and insulation. All Antarctic seals also have a layer of fur, giving additional insulation when they are hauled out on land or ice.
Does a whale eat a seal?
They feed on fish and squid like other toothed whale species, but will also target seals, sea birds and even other whale species - even if they are far bigger than themselves. Killer whales are also the only known predator of great white sharks.

How are dolphins whales and seals alike?

On Friday, a lobster diver made headlines when he described miraculously surviving being “swallowed” by a humpback whale off Cape Cod, Massachusetts.
What eats an orca?
Orcas are apex predators, which means they're at the very top of the food chain and they have no predators. Killer whales are some of the largest and most powerful animals in the ocean, and no other predator is able to challenge them.
Do seals have blood?
You might expect an animal much larger than a person to have much more blood, but it's not just because seals have bigger bodies. In our bodies, blood makes up 7-8% of our weight, but in a Weddell seal's body, blood makes up 20-22% of their body weight.
Are seals friendly?
Whilst they are strong and powerful with huge teeth these are highly unlikely to be used aggressively towards you – playfully yes, but even then they can be incredibly gentle. Surprisingly, I would say that seals are pretty good at 'reading' your intent or body language as high level mammals.

What animal did whales evolve from?
Both hippos and whales evolved from four-legged, even-toed, hoofed (ungulate) ancestors that lived on land about 50 million years ago. Modern-day ungulates include hippopotamus, giraffe, deer, pig and cow.
What animal did dolphins evolve from?
The evolution of dolphins, or Delphinus, is believed to have started with the Pakiectus, a four legged, land walking mammal. The Pakiectus dates back to approximately 50 million years ago. Throughout the centuries, these animals have gone through drastic changes to become the modern day dolphin.
What animals eat a seal?

Where is the whale cradling the Weddell seal?
The photo is extraordinary. In waters near the Antarctic peninsula, an enormous humpback whale floats on its back, cradling a Weddell seal on its chest and elevating it above the ocean surface. Only moments earlier, the seal was perilously close to becoming dinner for a group of hungry killer whales.
What was the whale attacking the crabeater seal?
In Antarctica, a killer whale was attacking a crabeater seal when a pair of humpback whales (one is pictured in the background) arrived and began to harass it. Robert L. Pitman. One account in the study described a killer whale attacking a gray whale mother and calf, when "out of nowhere, a humpback whale came trumpeting in.".
What animal would slap their tails in the water?
But belligerent humpbacks also appeared when orcas pursued other whale species, or even seals and sea lions. The humpbacks would slap their tail flukes and flippers in the water, and make loud "bellowing" sounds to drive the orcas away.
Why is whale behavior hampered?
He said that current understanding of whale behavior is also hampered simply because whales are scarce. Whaling throughout the 20th century drastically reduced their numbers, and many populations that were nearly eliminated are only recently beginning to rebound.
Which whales attack orcas?
The study found that large and powerful humpback whales, the only whales known to attack orcas, will band together and sometimes travel great distances to interrupt and terminate a killer whale attack, regardless of what type of animal the orca is attacking.
Can a humpback calf be saved from a killer whale?
Since the risk to a healthy adult humpback from a killer whale is low, the benefit of possibly saving a humpback calf could outweigh the high-energy cost of putting themselves in harm's way -- even if the animal they're saving isn't always a humpback, Pitman said. [ Whale Album: Giants of the Deep]
Do humpbacks attack whales?
But humpbacks frequently turned the tables on their would-be attackers. Observers also described numerous reports of humpbacks -- alone and in groups -- making the first move, approaching killer whales that were already pursuing other prey. Sometimes the orcas' victims were humpback mothers with young calves. But belligerent humpbacks also appeared when orcas pursued other whale species, or even seals and sea lions. The humpbacks would slap their tail flukes and flippers in the water, and make loud "bellowing" sounds to drive the orcas away.
Physical Characteristics
- Seals have unique physical characteristics. Like other mammals, they are warm-blooded and nurse their young, but, unlike other mammals, have large flippers instead of arms or legs. To withstand freezing temperatures, the seal’s body is covered in a slick, fur coat that is water-resis…
Diet
- Seals eat small marine prey, including shellfish, squid, and fish. Seals based in polar regions may eat penguins, seabirds, crab, krill, and other mollusks. Some species may hunt the pups of smaller seals. They are aggressive hunters and clutch their prey with their teeth, battering them against the ground until they are dead or, in the case of shell-fish, broken.
Social Structure
- Seals live in complex social structures that may seem anarchic at first. While they generally live in large groups with several hundred members, these groups are hierarchical. Smaller groups of dominant males lead the pack and even smaller cliques of seals may form around particularly desirable females. Traveling in large groups is a primary defense mechanism for seals, which ar…
Breeding
- Like other mammals, seals compete with each other during mating seasons. Male seals do not eat during mating season, which may last for up to ninety-days. Similarly, when nursing, female seals do not eat and their bodies are sustained by fat reserves. Dominant males may fight numerous, less aggressive males to access a female for mating and, depending on the species …
Habitat
- Although many seals live in arctic regions, some may be found in tropical beaches throughout the world. Global warming has had an adverse effect on seal populations and excessive blubber, which is commonly found on seals living in cold climates, becomes a maladaptive characteristic. Excessive fishing has also impacted seals, who may migrate for hundreds of miles for access t…
