Etymology
The term 'lepisosteid' comes from the scientific classification of these fish. The name is derived from the Greek words 'lepis', meaning 'scale', and 'osteon', meaning 'bone', which reflects the structure of their ganoid scales. The family Lepisosteidae was first described in the mid-19th century. Gars are some of the oldest freshwater fish, with fossil records dating back over 150 million years. Their unique anatomy, including a heavily armored body and a long, narrow snout filled with sharp teeth, has allowed them to survive through various geological periods. Their evolutionary history is fascinating as they have retained many primitive features, leading scientists to study them in the context of vertebrate evolution.
