Okay, I have a weird question. When animals are in the womb, do they have imbilical cords?

If that animal is a placental mammal, yes. And since the vast majority of mammals are, then yes they have an umbilical cord. They will also have a belly button. Marsupials are not placental mammals.

All mammals have umbilical cords in the womb.

The reason you don't see animals with bellybuttons is that the umbilical cords are differently shaped than ours. The area in the abdomen where it is usually grows together as they age and seems to disappear. Sometimes it doesn't and it can cause an umbilical hernia, sometimes seen most commomly in puppies.

They do have umbilical cords and belly buttons too. Look at the pendulous belly bottom of the cow ,it is hanging down you cant miss it. In other animals it is covered with hair but it is there.

Their belly buttons are on their bellies but are hard to see because first, you have to find a safe way to to take a look and second, they are covered in hair which makes it a little harder to find.

Yes all animals born live (not in eggs) have bellybuttons. And they are most likely covered with hair!

They do have umbilical cords and i don't know why they don't have belly buttons, they just don't.

As long as they're mammals
