Prionace glauca (Linnaeus, 1758)

Žralok modrý (Prionace glauca), někdy též žralok modravý či žraloun modravý, je druh živorodého žraloka dosahující délky více než 3 metry a váhy okolo 200 kg. Obývá hlubší, zejména chladné vody mírného a tropického pásu, ve kterých se dokáže potopit až do hloubky 350 metrů (obvykle okolo 200 m). Jedná se spíše o nočního lovce, který se živí převážně chobotnicemi, ale nepohrdne ani rybami, mořskými savci či ptáky. Druh je i přes své celosvětové rozšíření ohrožen, jelikož je komerčně loven. Odhady hovoří o 10–20 milionech každoročně ulovených žraloků. Proto je Mezinárodním svazem ochrany přírody (IUCN) hodnocen jako téměř ohrožený.
