Exposed Animal Bellybutton

Go To

Sometimes when you draw animals on any level of anthropomorphism from Nearly Normal Animal to Beast Man, but especially Civilized Animals, Funny Animals, Beast Man, you just give them a humanlike bellybutton, whether "innie" or "outie," that can be seen through their fur, feathers, or scales.

While some cartoon animals have humanlike bellybuttons, Real Life animals don't have navels like this. Placental mammals beside humans are born with a navel that looks very much like a scar.

Other animals, like monotreme mammals, all birds, most reptiles, amphibians, and fish, most insects, some molluscs, and some arachnids don't have navels, as they are oviparous (were born from eggs). Some squamates (the reptile group that includes lizards, snakes, and amphisbaenians) like rattlesnakes, sea snakes, slowworms, and garter snakes, are either viviparous or ovoviviparous (give birth to live young), as are most sharks, live-bearing bony fishes, some species of scorpion, cockroaches, and velvet worms. They don't have navels as navels are exclusive to placental mammals.

  • In Cinderella, in the scene when Gus is first introduced, Cinderella tries to put a shirt on Gus, but then the shirt rises and pops up. For a SPLIT second, you could spot a bellybutton on Gus while in the air. A little mistaken in the scene where Gus is trapped in the teacup that Lady Tremaine was about to pour tea into. As Gus jabs in his belly to avoid the boiling tea drop coming down, it seems as though he grew a bellybuttton, while it was really just lines indicating his belly is being pulled in. As his belly rises in relief, it still seems to have the shape of a bellybutton until it fully rises, where the mark disappears.
  • Stupid the weasel from Who Framed Roger Rabbit has a bellybutton.
