Acrodus is spelled using the IPA phonetic transcription as [əˈkroʊdəs]. The first syllable "a" is pronounced as "uh" while "cro" is pronounced as "kroh". The second syllable "dus" is pronounced as "duhs" with a silent "c" in the middle. Acrodus refers to a genus of prehistoric sharks that lived during the Mesozoic era. The name comes from the Greek words "akros" meaning high and "odous" meaning tooth, which accurately describes the shark's high, saw-like teeth.
Acrodus is a term that refers to an extinct genus of cartilaginous fish known as holocephalans, commonly referred to as ratfish or ghost sharks. These creatures lived during the Mesozoic Era, specifically the Jurassic and Cretaceous periods, approximately 147 to 66 million years ago. The name Acrodus is derived from the Greek words "akros" meaning "topmost" and "odus" meaning "tooth." The genus is characterized by its unique dental structure, having numerous sharp cusps on its upper jaw teeth.
Acrodus had a slender and elongated body, measuring up to several feet in length. They possessed a long, tapering snout and large, well-developed eyes, suggesting they were primarily visual predators. Unlike most contemporary shark species, Acrodus had a specialized crushing dental structure for feeding on hard-bodied marine invertebrates such as mollusks and crustaceans.
Fossils of Acrodus have been discovered in various locations around the world, including Europe, North America, and Asia. These remains provide valuable insights into the paleobiology of early cartilaginous fish and their evolutionary relationships. Studies of Acrodus fossils have also contributed to our understanding of the ancient marine ecosystems in which they thrived and their role in the ecological balance.
Today, Acrodus is considered to be a key genus for paleontological research, offering a window into the ancient world of marine life and the evolution of cartilaginous fishes.

The word "acrodus" has its origins in the Ancient Greek language. It is derived from the combination of two Greek words: "akros" meaning "high" or "topmost", and "odous" meaning "tooth". Therefore, "acrodus" translates to "topmost tooth" or "high tooth" in English. This term is often used in paleontology to refer to a group of extinct cartilaginous fish that lived during the Mesozoic era.
