Various factors may impact the processes of diversification of a clade. In
the marine realm, it has been shown that coral reef environments have
promoted diversification in various fish groups. With the exception of
requiem sharks, all the groups showing a higher level of diversity in
reefs than in non-reef habitats have diets based predominantly on
plankton, algae or benthic invertebrates. Here we explore the pattern of
diversification of carangoid fishes, a clade that includes numerous
piscivorous species (e.g. trevallies, jacks and dolphinfishes), using
time-calibrated phylogenies as well as ecological and morphological data
from both extant and fossil species. The study of carangoid morphospace
suggests that reef environments played a role in their early radiation
during the Eocene. However, contrary to the hypothesis of a
reef-association-promoting effect, we show that habitat shifts to non-reef
environments have increased the rates of morphological diversification
(i.e. size and body shape) in extant carangoids. Piscivory did not have a
major impact on the tempo of diversification of this group. Through the
ecological radiation of carangoid fishes, we demonstrate that non-reef
environments may sustain and promote processes of diversification of
different marine fish groups, at least those including a large proportion
of piscivorous species.
