Because they're big enough to be able to eat them under certain conditions.
Yes, orcas do eat beluga whales. They are known to be one of the predators of beluga whales in the wild.
Polar Bears and Killer Whales (Orca) are the two main predators of the beluga whale. Polar bears take particular advantage of situations when belugas become trapped by ice and are thus unable to reach the ocean. The bears swipe at the belugas and drag them onto the ice. The killer whale is its other significant natural predator.
there enemies are sharks and humans AND orcas/killer whales
The only whales that do not live in the ocean, are the ones found in captivity. Killer whales (or Orcas as they are commonly known), and Beluga whales are common in theme parks.
Orcas, also known as Killer Whales, have dorsal fins. Beluga whales do not.
The first three are for Australia and the others are common. Southern Right Whales Humpback Whales Orcas ( Killer whales ) Blue Whale Beluga Whale Fin Whale
The humpback whale's enemies are humans, killer whales (orcas), and sharks. Hope this helped... (bb_sweetlollipop)
Trick question: the barracuda is obviously not a whale. What is not so obvious is that orcas, although called killer whales, are also not true whales. Orcas are members of the same family of mammals as porpoises and dolphins.
peopleOrca's only enemy is ma, because orcas are feared by all animals.
Beluga whales are a very pretty creamy white. ** White Whale is another name for beluga whales! :)
Toothed whales (Odontoceti) this group includes dolphins and orcas. These whales eat meat. Baleen whales (Mysticeti)This group includes the Blue whale, Grey whale and Minke. They pull in a mouthful of seawater and feed on plankton.
Beluga whales are white.
