which bird/mammal has no predator?

Ok..take us out of the equation as we have predators too, Lions, bears etc all attack us and we attack pretty much anything.

I'd say Crocodiles have no other predator after them once they reach adulthood, as when they are eggs other animals will eat them. Alligators too.

Bears too, the large ones have no predators except man. Kodiak and Polar Bears for example.

Killer Whales are pretty safe as they have been known to attack Great Whites and not vice versa.

The large birds don't seem to get much trouble. Condors, Vultures, Sea Eagles etc.

Large whales are attacked by pods of Killer Whales so they're on the food chain as are elephants which have been known to be attacked by lions in extreme circumstances.

Technically, no animal is completely immune to predation, not even humans. Shark school sometimes hunt and kill whales, loins sometimes hunt elephants, eagles get attacked by flocks of crows, sharks by killer whales, loins by hyena, the list covers every living thing. We call it a "Food Chain" most of the time but "Food Web" is more accurate seeing as everything is eaten by something. Including us, you hear all the time about people getting killed by sharks, bears, or what have you. So then, no mammal or bird is completely free of predators, a few just come closer then others.

Well it is all how you look at it. Most elephants have no natural predators, except in Tsavo, Kenya and Okawango Delta in Botswana where lions eat them. The same goes for the Cape buffalo. Full grown crocodiles are not prey animals, nor are bears and wolves. Most of these animals are only hunted by humans. Any large predator has few to no animals that hunt it. Only the young has to fear other animals and the grown ones are normally hunted by humans. So for the large and powerful it is no natural predators, but humans hunt them. Humans are only killed by big animals for food, such as lions or tigers etc., If they go in to their range (home). Hope this helps. As I said it is all how you look at it.

Humans are the top predator and are killing off all other birds and mammals. Even humans are predated on by other humans.

Well humans are. Even though we still get killed by other animals we are at the top. The lion is at the top of it's food chain but still get killed by buffalo and elephants.

The act of being at the top places us in the sights of many 'lesser' species, so humans have lots of predators. Don't get smug and complacent!

With Man around nothing is safe. Exclude Man and you free up a few.

Rhinos are fairly safe. But, the most ferocious animal I have seen is the Honey Badger this animal is scared of nothing.

Humans- we are at the top of the chain.

im not sure... but these animals maybe are top predators

sharks, crocodile, vultures, . . . .

UR FACE!
