The pink body of this leech may reach a length of 3 cm. It has no eyes. It may be confused with the slightly larger C. lophii, living almost exclusively on monkfish. The rear sucker of C. nodulifera is approximately twice the size of the front sucker, while the corresponding ratio of the C. lophii is 4:1.
This leach is registered in the western as well as eastern parts of the North Atlantic Ocean.
