Vinegar eels are free living, non-parasitic nematodes that feed on the material known as the "mother of vinegar". When you realize the amount of small living creatures we ingest on a daily basis, vinegar eels are truly no cause for concern. They occur in raw vinegars commonly but not always. If you have ever had raw apple cider vinegar then chances are they were there. The health benefits far outweigh the squeamish factor.
The types of eels are salt water eels, freshwater eels, the swamp eels, rubber eels and the electric eels. It is an elongated fish that lives in the shallow waters.
