@stound They’re like in their hips, bizarre

@ImRileyTheDog kinda sorta, it's a weird adaptation, I suppose.

@stound Resembles my ex wife..

@baben30 Attached to their fins???

@ImRileyTheDog inside their fins. like fingers that webbed over completely.

@stound @baben30 Here’s another question...

Do animals have belly buttons?

@ImRileyTheDog only mammals. most mammals. placental mammals.

@baben30 Majority don’t, right? Like where do you see a belly button on a snake? Dog? Cat? Mouse? Fish? PENGUIN? They have one in the womb but then it disappears?

@ImRileyTheDog snakes, fish, and penguins all come from eggs, there'd be no placenta connection. none of them are mammals. the others should.

@stound Bears? Pandas? Whales? Dolphins? I mean I’m sure they have them, just not visible.

@ImRileyTheDog they're harder to find, usually, but all should have them. the exceptions being things like the possums and platypus.

@stound I believe you, but I think it’s funny when you pet a dog or cat you can’t see them but you can see where their umbilical cord was
