Australian seriolella (Seriolella brama) from the family centrality, as well as Escolar or gray delicacy mackerel (Lepidocybium flavobrunneum) from the family gimpelevich.

Epipelagic sharks-planktology filter huge amounts of water and thus receive the necessary amount of food in places of mass accumulations of planktonic organisms,so the whale and especially of basking sharks clearly feed migration.
