This week on World of Sharks we are diving into the world of an iconic species: the blue shark, Prionace glauca. Known for their big eyes, pointed snouts, mesmerising metallic blue colour and inquisitive nature, blue sharks are a species of requiem shark that occur in temperate and tropical oceans around the world. We are joined by Dr Jenny Bortoluzzi, shark scientist and SOSF project leader, who studied this species in Irish waters for her PhD and tried to understand why they came to the area in such large numbers, and discovered some quite surprising things about their eating habits… Digressions include some very friendly sunfish, travel-happy porbeagles, and why on earth a shark would choose to eat jellyfish. Time stamps: Jenny's life and career [6.30-20.10], blue sharks and Jenny's research [20.20 - 45.00], porbeagle tagging [45.30-49.50], conservation implications [50.00].
