The Lions Mane Jellyfish is the largest jellyfish in the world. They have been swimming in arctic waters since before dinosaurs (over 650 million years ago) and are among some of the oldest surviving species in the world.
Thousands of starlings surround a lone bird of prey which had had swooped down to pick off a straggler. "Starlings have a very particular way of defending themselves from their predators like falcons and harriers. They form a large tightly packed flock and mob their enemy, scaring it off, frequently expanding and contracting and changing shape."
