Why do most animals just not have belly buttons?

578 viewsBiologyOther

does it serve a purpose for us to still have them aside from the obvious? i mean after birth. what about for animals *not* having them once they’re born? i was wondering specifically about rats and puppies. i’ve had both as babies and they all had a little black spot for a week or two, then it disappeared for good. when the rats were still pink with no fur i actually saw the black spot dissipate over time within like a week and a half or so

My goats gave birth two weeks ago to four amazing little babies. Each one has an umbilical cord attached, but they’re much thinner than human cords. One of them already shriveled up and fell off of one of the babies; I’ll report back soon to see if I can see/get a picture of a belly button!
