    So yeah, all mammals have breasts. Mammal comes from mammary. Is this not taught in schools anymore?

    This was like primary school science for me when growing up - like 8-9 years old - and repeated on biology throughout highschool.

    Or is it interesting because generally people don’t post pictures of elephant breasts?

      Not all mammals have visible / human like breasts. That’s what this is about.

      I suppose it’s interesting because we assume that most mammals have their mamary glands further down, like dogs or cats, not on the torso like humans do.

        Don’t most start at the torso? Cats and dogs have large litters, so 8(?) nipples starting at the ribs going down.

          I think a lot of people base their assumptions on the way cows, goats, sheep and deer have their mammaries positioned between the waist and the rear legs.

          (Waist? Seems wrong but midline is also confusing.)

          Those also have hooves, and elephants don’t, but it’s the animals we’re used to seeing nurse.
