Size / Weight / Age
Attacks like a leech and produces wounds all over the fish which it attacks. It spreads a bundle of opercular and inter-opercular spines into the wound and remains there, being very difficult to remove. Invades the 'private parts' of wading or swimming animals but apparently exist in these passages only for a short while, as they quickly die from a lack of oxygen (Ref. 6868).
