👉 Ichthyobronema, also known as the "crown of the fish," is a type of vertebrate that belongs to the order Chordata (fishes) and is characterized by its distinctive crown-like structure on its head. This characteristic helps in distinguishing it from other types of fish such as ray-finned fish. Ichthyobronema is often found in freshwater environments, particularly those with a high concentration of nutrients like nitrogen.
