🦈Common thresher

Alopias vulpinus (Bonnaterre, 1788)

Kettuhai (Alopias vulpinus) on valtamerten trooppisissa ja lauhkeissa osissa elävä noin kuuden metrin pituinen hai, jonka pyrstöevän ylälohko on yhtä pitkä kuin muu ruumis. Pyrstönsä avulla se ajaa pieniä kaloja tiiviiksi parveksi ja käyttää sitä lyömäaseena kalojen tainnuttamiseen. Yleensä kettuhait oleilevat ulapalla mutta voivat varsinkin kesällä saalistaa rannikollakin.
