*Abstract*
Parasite biodiversity in cetaceans represents a neglected component of
the marine ecosystem. This study aimed to investigate the distribution
and genetic diversity of anisakid nematodes of the genus Anisakis
sampled in cetaceans from the Northeast Atlantic Ocean and the
Mediterranean Sea. A total of 478 adults and pre-adults of Anisakis spp.
was identified by a multilocus genetic approach (mtDNA cox2, EF1 α − 1
nDNA and nas 10 nDNA gene loci) from 11 cetacean species. A clear
pattern of host preference was observed for Anisakis spp. at cetacean
family level: A. simplex (s.s.) and A. pegreffii infected mainly
delphinids; A. physeteris and A. brevispiculata were present only in
physeterids, and A. ziphidarum occurred in ziphiids. The role of
cetacean host populations from different waters in shaping the
population genetic structure of A. simplex (s.s.), A. pegreffii and A.
physeteris was investigated for the first time. Significant genetic
sub-structuring was found in A. simplex (s.s.) populations of the
Norwegian Sea and the North Sea compared to those of the Iberian
Atlantic, as well as in A. pegreffii populations of the Adriatic and the
Tyrrhenian Seas compared to those of the Iberian Atlantic waters.
Substantial genetic homogeneity was detected in the Mediterranean Sea
population of A. physeteris. This study highlights a strong preference
by some Anisakis spp. for certain cetacean species or families.
Information about anisakid biodiversity in their cetacean definitive
hosts, which are apex predators of marine ecosystems, acquires
particular importance for conservation measures in the context of global
climate change phenomena.
