shield‑hand sea cucumbers (historical taxon)
Etymology
'aspidochirota' originates from New Latin, ultimately from Greek elements 'aspis' meaning 'shield' and 'cheir' meaning 'hand', combined in a taxonomic formation to denote 'shield‑handed' forms.
'aspidochirota' was used in older zoological literature (often as 'Aspidochirotida' or similar New Latin endings) to name an order or subgroup of Holothuroidea; later systematic revisions split or redistributed these taxa into other orders and the term fell out of regular use.
Initially it literally referenced 'shield‑handed' morphology (tentacles or podia resembling a shielded hand); over time it became a formal taxonomic name for a group of sea cucumbers and has since become mostly an obsolete/classificatory historical term.
Meanings by Part of Speech
Noun 1
a (historical) taxonomic grouping of sea cucumbers (class Holothuroidea), originally used to denote forms with shield‑like (aspid-) tentacular structures; now largely obsolete, with its members redistributed into other orders or clades.
Early 20th century textbooks frequently listed aspidochirota as a major subgroup of sea cucumbers, though modern classifications no longer recognize it as a valid order.
