group of sea squirts
Etymology
'ascidioida' originates from New Latin, built from the genus name 'Ascidia' (from Greek 'askidion' meaning 'little bag') plus the suffix '-oida' (from Greek 'eidos', meaning 'form' or 'resembling').
'ascidioida' developed as a taxonomic name in Modern/Neo-Latin usage in zoology, formed from the genus 'Ascidia' to denote a group of ascidian-like organisms and used in 19th–20th century classifications of tunicates.
Initially it conveyed the idea of 'those resembling Ascidia' (Ascidia-like organisms); over time it became fixed as a formal taxonomic name for an order of ascidians (sea squirts).
