The Blue Shark (Prionace glauca) is a sleek, fast-swimming predator recognised for its slender, torpedo-shaped body and vibrant blue colouring. Commonly found in deep, open oceans worldwide, blue sharks are highly migratory, covering vast distances in search of prey like squid and small fish. Known for their agility and graceful movements, they play an important role in maintaining marine ecosystems. Blue sharks are social and often form groups based on size and gender, making them unique among shark species.
