Sperm Whale vs. Orca Whale?

Question

Who would win on a 1 on 1 fight?

Answer 1

1 on 1 most likely the sperm whale just because of sheer size, however that is unlikely to occur a lone orca would probably not attack a sperm whale but they usually occur in pods and pods have been known to attack and kill sperm whales;

KILLER WHALE PREDATION ON SPERM WHALES: OBSERVATIONS AND IMPLICATIONS

In October 1997 we observed a herd of approximately 35 killer whales (Orcinus orca) attack a pod of nine sperm whales (Physeter macrocephalus) 130 km off the coast of central California. During the four hours we watched, adult female killer whales, including some with calves, attacked in waves of four to five animals in what was apparently a “wound and withdraw” strategy. Adult male killer whales stood by until the very end when one charged in and quickly killed a seriously wounded sperm whale that had been separated from the group. The sperm whales appeared largely helpless: their main defensive behavior was the formation of a rosette (“marguerite”—heads together, tails out). When the killer whales were successful in pulling an individual out of the rosette, one or two sperm whales exposed themselves to increased attack by leaving the rosette, flanking the isolated individual, and leading it back into the formation. Despite these efforts, one sperm whale was killed and eaten and the rest were seriously, perhaps mortally, wounded. We also present details of two other encounters between sperm whales and killer whales that we observed. Although sperm whales, because of various behavioral and morphological adaptations, were previously thought to be immune to predation, our observations clearly establish their vulnerability to killer whales. We suggest that killer whale predation has potentially been an important, and underrated, selective factor in the evolution of sperm whale ecology, influencing perhaps the development of their complex social behavior and at-sea distribution patterns.

Answer 2

Sperm Whale

Answer 3

It is obviously the Sperm Whale because if it can KILL a giant squid it can beat an Orca Whale.

Answer 4

sperm whale

Answer 5

Sperm Whale, it is much larger and more muscular.

Answer 6

Sperm whale -- hands down. They can dive deeper, larger, and more powerful, and I believe faster.

Answer 7

orca's kill baby whales if they only have their mothers with them

Answer 8

my bet is on a killer whale pod.
but only under the right circumstances.

Answer 9

Orca would win because it is very intelligent.

Answer 10

The orca will win, it has big teeth, the sperm whale has no teeth.
