A mynock  a SW világegyetem "vándorpatkánya, ott van kb mindenhol.  ott ép egy úrcsigában. Nem szimbiózis

Despised by starship captains, mynocks are leathery-winged parasites found winging through deep space, roosting in asteroid fields and sometimes lurking in damp locations, including the innards of space slugs. Mynocks chew power cables and devour energy conductors, and can drain a starship’s energy reserves. Wise captains check for power fluctuations and other signs of infestations, cleaning off mynocks in port before raising ship.
