Description

The shell grows to a length of 55 mm. Individuals can grow to 58.2mm and can have a wet body mass of 24.5g.[2] Dead Zemacies excelsa form shallow marine sediments. Unlike most of its close relatives in the Conoidea superfamily, Z. excelsa lacks a radula and venom apparatus.[3]

Zemacies excelsa has a dextrally coiled body symmetry.[2]

Distribution

This species occurs in the Pacific Ocean off New Caledonia and New Zealand. Most are found approximately 200-300 meters deep in the ocean, with some down to 600-700 meters deep.[4]
