I’m gonna regret this… so tell me about their testicles? Size of basketballs or something?

Yes, male sperm whales possess testes, which are the equivalent of "balls" in other mammals. However, unlike most terrestrial mammals, their testes are internal, located within the abdominal cavity rather than in an external scrotum.

Size: Sperm whale testes are remarkably large, particularly in mature males. A single testis can weigh up to 500 kilograms (over 1,100 pounds), making them among the largest testes in the animal kingdom, both in absolute size and relative to body mass. This enormous size is thought to be an adaptation related to sperm competition, where larger sperm reserves can increase reproductive success.

yes that is one large, loud, flammable fish that certainly has warm blood and gives live birth and lactates. We shall name it after the yet to be observed massive and majestic balls it will most certainly have somewhere in its belly.

It definitely has majestic balls, though, so they lucked out on that one

More like the size of a VW Beetle. It's why they're called sperm whales.

They're called sperm whales because of the spermaceti organ, which is probably used to make them loud as fuck, and which contains a liquid which whalers mistook for sperm.

So the testes make sound too? Thats amazing

Imagine the sound when they have an orgasm. Announcing to the planet that they're getting it on. No kid would be safe from the sound of their parents having sex and vice versa.
