Are rabbits the most sexually active animals on earth?

Rabbits are indeed known for their high reproductive rates, with a female rabbit capable of producing several litters each year, sometimes resulting in dozens of offspring. However, they are not the most sexually active animals on Earth. Species like certain insects, such as the fruit fly, exhibit even more prolific mating behaviors relative to their lifespans. Thus, while rabbits are highly reproductive, they are not the top contenders for sexual activity in the animal kingdom.
