The idea that it is funny to see wild animals coerced into acting like clumsy humans, or thrilling to see powerful beasts reduced to cringing cowards by a whip-cracking trainer, is primitive and medieval. It stems from the old idea that we are superior to other species and have the right to hold dominion over them.

Aquatic animals suffer from the disadvantage that they cannot scream when in pain, so we find it hard to gauge the degree of their agony. If fish could scream, angling purely for sport would be outlawed without delay.

There is nothing biologically unusual about a homosexual act of pseudocopulation. Many species indulge in this, under a variety of circumstances.
