The consanguinity of cetacean parents is far enough for reproductive isolation in higher animals, and the unexpected harvest seems to prove some unknown biological genetic mysteries.
They belong to the dolphin family.
But the following categories are completely different:
One is the bottlenose dolphin (Montagu, 182 1).
One is the fake killer whale (Owen, 1846), which belongs to the fake killer whale of the family Cetacidae.
The two kinds of whales belong to the same family and different subfamilies, so it can be said that they can't even get together in estrus. As long as higher animals don't belong to the same family, they can't naturally cross in estrus. Even tigers, mules and cows of the same family have very high premature mortality and social disorder. This strange phenomenon of whale hybridization seems to have broken some previously generally accepted theories, and it is an event worth studying.
