摘要：Recent cave diving explorations in Cenote Crustacea have led to discoveries of several undescribed annelids inhabiting sediments that lie within the halocline and marine layers. Taxonomic and genetic evaluations support their placement within Acrocirridae and Flabelligeridae, establishing new records from anchialine systems for these families. This study highlights the need for continued exploration and investigations of these mysterious labyrinths.
