apparently been willing to see if it would continue to the point of
feeding. It would no doubt do so, as the Pacific lamprey, Entosphenus
tridentatus, has been recorded found attached to warm-blooded, marine

In the pacific lamprey account on page 45, the authors cite Pike (1951)
when discussing lamprey bites on marine mammals.
