However, this study did not
take into account the size/age of turtles. As loggerhead turtles age
they switch from pelagic to demersal foraging, affecting their likelihood
to ingest debris (Plotkin et al., 1993;
but note there is some overlap in
foraging modes among turtles with carapaces 26–80 cm, Casale et al.,
2008).
For example, the incidence of plastic in loggerhead turtles sampled
off Brazil was greater in small individuals (25% for animals with
carapaces b 40 cm, compared to 12% of animals N 40 cm;
