Article Synopsis
- The deep-sea acorn worm Quatuoralisia malakhovi belongs to the phylum Hemichordata and possesses unique anatomical features due to its epibenthic lifestyle and habitat, yet its morphology remains under-researched.
- The research involves detailed histological analysis of the reproductive system, revealing that Q. malakhovi has separate sexes that are externally indistinguishable and includes observations of the testicular structure and function.
- Findings include specific details about testis architecture, the absence of yolk cells, and the fine structure of spermatozoa, which are characterized by an acorn-shaped head and a long flagellum.
