👉 Remotididymella is a type of freshwater fish that is part of the order Chondrichthyes, which also includes bony fish like ray-finned fish and sharks. It is known for its unique structure, consisting of a single chambered sac called a remodilidomery, where sperm and eggs are stored. This unique feature has been studied in the study of demersal ichthyology to understand how freshwater fish adapt their reproductive strategies to aquatic environments.
