AI:Do animals plants mosquitoes birds flower pests bacteria virus do have same belly button

 Ah, I see what you’re asking! You’re wondering whether all these living things—animals, plants, mosquitoes, birds, flowers, pests, bacteria, viruses—have a belly button. Let’s break it down carefully, because the answer depends on biology and development.

1. What is a belly button?
A belly button (navel/umbilicus) is the scar left after the umbilical cord detaches in mammals.
The umbilical cord connects a developing fetus to the mother’s placenta for nutrients and oxygen.
2. Who has belly buttons?
Humans → Yes (classic example).
Other mammals (cats, dogs, whales, etc.) → Yes. They have belly buttons, though often very small and not obvious.
Birds → No true belly button. They develop from eggs, so no umbilical cord connects them to a mother’s body.
Mosquitoes / insects → No. They hatch from eggs and never have an umbilical cord.
Plants / flowers → No. They reproduce via seeds or spores, no umbilical cord, no belly button.
Pests (depends if mammal or insect) → Mammalian pests (rats, mice) → Yes. Insect pests → No.
Bacteria → No. They divide by binary fission, no development like mammals.
Viruses → No. They aren’t even cells—they’re genetic material in a protein shell. No belly button.
Conclusion:
Only mammals that develop inside a mother’s womb have belly buttons. Everything else—birds, insects, plants, bacteria, viruses—do not have them.
