#amfioxus

It identifies the same small marine animal from the subphylum Cephalochordata, widely utilized in international academic literature and evolutionary biology university textbooks.
• Amphioxus — The common or historical scientific name (genus Amphioxus) used in zoology to designate the lancelet (scientifically known as Branchiostoma lanceolatum), a small, translucent, lance-shaped marine invertebrate belonging to the Chordata phylum (subphylum Cephalochordata). It represents a fundamental reference organism in the study of comparative anatomy and vertebrate evolution, as it retains a simple structural dorsal notochord throughout its entire life cycle without developing a bony vertebral column.
