abrachias
n. C2 Proficiency abrachias
n. a type of ancient fish that lived in the sea. These fish are known for having a unique shape and are often studied by scientists to learn about how life evolved.
n. an extinct order of marine jawless fish that lived during the Paleozoic era. Characterised by a distinctive, elongated body and a lack of paired fins.
Scientists study abrachias to understand ancient ecosystems.
Fossils of abrachias were discovered in the limestone layers of the coastal cliffs.
The evolutionary transition from abrachias to more modern jawed vertebrates represents a significant milestone in the diversification of early marine life.
