A deformity, dysmorphism, or dysmorphic feature is a major abnormality of an organism that makes a part of the body appear or function differently than how it is supposed to.

Causes

Deformity can be caused by a variety of factors:

Deformity can occur in all organisms:

Mortality

Case of acephalus holoacardiacus – born without a head. Was birthed alongside a healthy twin.[3]

In many cases where a major deformity is present at birth, it is the result of an underlying condition severe enough that the baby does not survive very long. The mortality of severely deformed births may be due to a range of complications including missing or non-functioning vital organs, structural defects that prevent necessary function, high susceptibility to injuries, abnormal facial appearance, or infections that eventually lead to death.

In some cases, such as that of twins, one fetus is brought to term healthy, while the other faces major, even life-threatening defects. An example of this is seen in cattle, referred to as amorphous globosus.

In mythology

There are many instances of
