👉 Bicornus is a term used to describe the shape of a horse's tongue, which is formed by the development of two separate tongues. The first tongue is called the "biconcave" tongue and is often shorter in length than the second tongue, which is known as the "biconcholate" tongue. Bicornus can be found in many different breeds of horses, including those with a long coat called the "long-biconceal" coat or those with short coats
