SELACHOSTOMI Meaning and
Definition
-
Selachostomi is a scientific term that refers to a group of extinct jawed fishes belonging to the class Agnatha, which are commonly known as the jawless fishes. This group is characterized by their cartilaginous skeleton, lack of paired fins, and their unique snout-like protrusion, known as a rostrum, which often exhibits a toothed or beaked structure.
The Selachostomi encompass several families of fishes, such as the Ateleopodidae, Carapelaeopodidae, Cladoselachidae, Diplodontidae, and many others. These fishes were globally distributed during the Devonian and Carboniferous periods, which occurred around 419.2 to 298.9 million years ago.
Selachostomi possessed a variety of feeding strategies. Some species were scavengers, while others were predators, using their sharp, conical teeth to capture and consume prey. Despite their lack of paired fins, these fishes were successful swimmers, relying on their elongated bodies and undulating movements to propel through the water.
Fossils of Selachostomi have been discovered in various geological formations and are highly valued by paleontologists for their importance in elucidating the evolutionary history of jawed fishes. They represent an early stage in the emergence and diversification of jawed vertebrates, providing valuable insights into the origin and development of important features seen in modern fishes.
In conclusion, Selachostomi is a taxonomic grouping representing a diverse collection of extinct jawless fishes that flourished millions of years ago. These fishes played a crucial role in the evolutionary narrative of vertebrates, and their study contributes to our understanding of the ancient aquatic ecosystems.

Etymology of SELACHOSTOMI
The word "Selachostomi" is derived from two Greek roots: "selachos" and "stoma".
- "Selachos" (σέλαχος) means "shark" in Greek. It is derived from the Proto-Indo-European root *sel(e)k-, which means "fish" or "eel".
- "Stoma" (στόμα) means "mouth" in Greek. It is derived from the Proto-Indo-European root *steh₂-, which means "mouth" or "to speak".
When combined, "Selachostomi" refers to a group of fish known as "selachostomes", which are characterized by their shark-like appearance. They are cartilaginous fishes belonging to the subclass Elasmobranchii and include various species such as hagfishes and lampreys.
