David Warren considers the parallels between certain dolphin behaviour and its human equivalent:
I am, let me confess, no expert on dolphins, nor on any other member of the cetacean paraphyly. Nor, for that matter, on anything at all, in my current recollection. I do however know that dolphins can swim very fast, can leap high out of the water, can be as long as thirty feet, and that even small dolphins, no longer than a man, are very strong. I would not mess with one in the water. Before assuming that their behaviour, in the state of nature, is entirely benign, one should ask some fish. Even a porpoise could tell you: they have their dark side. Especially a porpoise: for dolphins have been known to murder hundreds of them, for no stated reason. They can take a dislike to each other, too; and for reasons that we may darkly surmise, act upon what we take for their emotions.
Example: when they throw each other’s children in the air, they are not being playful.
On at least one occasion I have had to explain to an environmentalist that the sob-story he was telling, about dolphins found dead or dying on a Virginia beach, had nought to do with capitalist perfidy. On forensic examination, all the beached dolphins were found to have suffered severe blunt-force trauma — administered by other dolphins.
They have also been known to dislike humans, for instance pulling them under the water until they stop making bubbles. Brooding, “loner” dolphins are particularly noted for the sort of behaviour that we might be inclined to characterize as evil.
Smiley-face, bottlenose dolphins, of the Tursiops genus, are among those sexually dimorphic, which is to say, the males are decidedly bigger than the females. They are very smart, in both sexes, but not nearly as sentimental as our New Age propagandists have advertised. I cannot imagine a feminist being pleased with their courting rituals, which closely resemble entrapment and rape. I take an unsentimental view of the dolphins myself, though I am prepared to admire their skills. I cannot believe male dolphins are gentlemen.
A story forwarded to me this morning from the London Telegraph tells a commonplace tale. A bottlenose dolphin has been terrorizing swimmers off a beach in Brittany. A loner male, with a marked preference for human females, has alas “progressed” from being a source of entertainment. The theory is that he is sexually frustrated. This strikes me as possible, but possibly narrow. I have read several stories before — from different continents — in which just such a loner male dolphin graduates from public entertainer, to public nuisance, to public danger, around a specific beach. In every case it seems the dolphin is believed to be sexually “aroused.” I would not be surprised to learn that the same symptoms accompany psychopathic behaviour in dolphins, as they often (if not always) do in rogue loner humans.
