Describing jellyfish or similar organisms that lack a velum or similar protective membrane structure.
From acraspeda, the adjective form describing the condition of lacking a kraspis. The -ote suffix in Greek scientific nomenclature indicates a quality or state of being.
This anatomical feature—the missing velum—became so important to jellyfish classification that scientists built an entire identity around its absence, showing how one missing body part can redefine an organism.
