Nectocaridida

Nectocaridida is an extinct group of marine creatures that lived during the Cambrian period, around 500 million years ago. They are considered to be early relatives of modern arthropods, which include insects and crustaceans. Nectocaridids had a unique body structure, with a segmented body and a distinct head, featuring large eyes and spiny appendages. They are important in understanding the evolution of complex life forms, showcasing how early life adapted to their environments. Fossils of Nectocaridida help scientists piece together the history of life in ancient oceans.
