What is Janus Animal?

The Janus animal is a term used in Biology to describe an organism that exhibits two distinct physical forms or features, resembling the two-faced Roman god Janus. This phenomenon can occur in various species due to genetic mutations, developmental anomalies, or environmental factors. An example is a creature with two heads or two sets of limbs, which can impact its survival and behavior. Janus animals are often studied to understand developmental processes and genetic expression.
