WebFu et al. investigated ontogenetic changes of the caudal fin and head shape in tiger sharks and found a shift from conical to broad and blunt head shapes with increased size and age. They assumed a correlation between a blunt head enabling a larger attachment area for muscles (Huber et al., 2009 ) and the possibility for the sharks to prey on larger and …
