Abstract

The sharksucker, Echeneis naucrates, attaches to a variety of hosts including teleost fish, elasmobranchs, marine turtles, and mammals. We list 18 additional hosts not previously recorded for this species, including the first report of its attachment to a conspecific and review the possible role of the relationship between echeneid fish and their hosts. The attachment of E. naucrates to a conspecific represents an addition to known hosts for this species, but it remains unclear if remoras are a habitual host for conspecifics.
