Range o the blue shairk

The blue shairk (Prionace glauca) is a species o requiem shairk, in the faimily Carcharhinidae, that inhabits deep watters in the warld's temperate an tropical oceans. Preferrin ceuler watters,[3] blue shairks migrate lang distances, such as frae New Ingland tae Sooth Americae. The species is leetit as Near Threatened bi the IUCN.

They feed primarily on smaw fish an squid, awtho they can tak lairger prey. Maximum lifespan is still unkent, but it is believit that they can live up tae 20 years.[4]
