. Sea lampreys handled for other research projects were examined for the presence of tumours. Nine tumours were found including: an ectopic notochordal mass, an epidermoid cyst, an ectopic paranotochordal haematopoietic myeloid mass, and six teratomas. The composition of these sea lamprey tumours did not differ significantly from that of similar lesions in higher vertebrates and thus they were similarly classified. The prevalence of tumours in our specimens was relatively high (1:19).
