Note: ETYFish and FishBase started a collaboration to complete the etymology for all valid names of fishes. For the current update, the following groups were completed: hagfishes (Myxini), lampreys (Petromyzonti), chimaeras (Holocephali), and sharks (Squalomorphi). It is a work in progress, so the two websites may not be synchronized.
