Photographer Beverly Heacker went on a walking expedition to capture images of bird species in Georgetown, Texas, USA, when she discovered a water snake engulfed in the mouth of a significantly larger catfish.
The water snake coils around the head of the catfish, struggling to engulf its prey completely.
The black water snake is a non-venomous species. They rely on their large, muscular bodies to constrict and suffocate their prey before swallowing it whole.
