All animals have to remove bodily waste from their system
No - it's a defence mechanism. They drop their tails to escape being captured (or eaten). Skinks do not reproduce asexually.
Skinks drop their tails as a defense mechanism known as autotomy. When threatened by predators, they can shed their tail to distract the attacker, allowing them to escape. The detached tail may continue to move, further diverting the predator's attention. This ability helps increase the skink's chances of survival, although they do eventually regenerate the lost tail, albeit with some differences in appearance.
Drop-tail skinks eat fruits and vegetables, but vegetables have to be cooked before they will eat them. The drop-tail skink is a small common skink often seen in suburban gardens in Melbourne, Perth, Sydney and Brisbane in Australia.
Skinks
through a vent beneath its tail
yes, but loses it's markings.
A person typically has hair under a pony tail. Under a pony's tail is their anus which is where they defecate from.
Pigeons do not defecate on the wing, but must be landed to defecate. Their legs grip the base of the tail during flight to increase streamlining, and means they cant defecate on the wing as other birds do, such as seagulls.
through a small hole called a vent beneath their tail
A boy skink will have a bump underneath the tail a girl will have a closed up hole
Hibernating bears produce feces but do not defecate. They produce something called fecal (or poop) plug which they drop when they leave the den.
Just like horses or donkeys. Lift tail, relax spinchter, push.
