-Bird.
Explanation;
-Birds reproduce by internal fertilization, during which the egg is fertilized inside the female. Birds have cloaca, or a single exit and entrance for sperm, eggs, and waste.The sperm from the male is transferred to the female when they touch cloaca, an act referred to as the cloacal kiss.
-Birds' eggs get fertilized inside the female bird's body, before the shell is formed. Then each egg comes out before any development of the fertilized egg starts.

The proteins of the membrane serve many purposes: transport, receptors, etc. The cell membrane is amphipathic, meaning is has hydrophilic and hydrophobic regions.

Answer:
Vestigial structures are structures in the body that no longer serve a purpose but the organism has not lost them through evolution because the feature doesn't harm the organism.
In other words, it's a structure that used to have a purpose but doesn't anymore, so it's kind of just there.
Therefore, some animals don't have vestigial structures because they never lost the purpose of that structure. If it still serves a purpose, it can't be vestigial.
On the other hand, the feature could have become detrimental, meaning it caused the organism harm, in which case, over time, the species would evolve not to have them anymore.
