Are whales smarter than dolphins?

Dolphin communication is so great that there is a strong possibility that a dolphin can send a sound image of say a fish to other dolphins.

What is the IQ of an orca?

Orca intelligence hasn’t been studied as intensively as the intelligence of bottlenose dolphins, but orca EQ has been pegged at around 2.5. Toni Frohoff, research director at TerraMar Research, is confident that orcas are not dumb animals.

Are killer whales smarter than humans?

Bigger animals typically have bigger masses of brain cells. But scientists use brain-weight-to-body-weight ratios as a rough measure of intelligence. By that measure, human brains, by comparison, are seven times average. In other words, orcas might be even much smarter than the size of their big brain suggests.

Why do killer whales not attack humans?

There are a few theories about why orcas don’t attack humans in the wild, but they generally come down to the idea that orcas are fussy eaters and only tend to sample what their mothers teach them is safe. Since humans would never have qualified as a reliable food source, our species was never sampled.

Can orcas understand humans?

New research reveals that orcas are able to imitate human speech, in some cases at the first attempt, saying words such as “hello”, “one, two” and “bye bye”. The study also shows that the creatures are able to copy unfamiliar sounds produced by other orcas – including a sound similar to blowing a raspberry.
