The warm-water nemertean species Paradrepanophorus crassus, described from Mediterranean shores, was first recorded in Lough Hyne, County Cork, Ireland in 1931 by Renouf. This large nemertean that forms membranous tubes under low intertidal to shallow subtidal rocks has increased in frequency, particularly from 2009 to 2012 with peak values of 0.26 specimens per metre of shoreline. Eggs were noted within the membranous tube of one specimen collected in June 2012. Furthermore, based on digital photographs of specimens, the striped nemertean species Punnettia splendida was also noted in September 2011; this is a new species record for Lough Hyne.
