Sharks

The truth about sharks: Far from being 'killing machines', they have personalities, best friends and an exceptional capacity for learning - Nature - Environment - The Independent

Turn off the spine-tingling music and forget everything you thought you knew about this solitary, "mindless killing machine". Sharks have individual personalities. They socialise, choose best friends and create social networks of unusual complexity. They can be trained by humans to complete simple tasks, much more quickly than rabbits or cats, for instance, and retain the knowledge for much longer. Sharks also teach each other new tricks: how to find food, identify predators and charm mates. Like sea turtles, some travel huge distances to return to their own birthplace, again and again, to give birth themselves. Most don't need to swim continuously to survive. And rather than being near-blind and reliant on smell, which is the general perception, they in fact have advanced sight. They feel pain. And the boldest sharks face a greater risk of dying before adulthood.

Why does any of this matter? Well, we're killing about 100 million sharks every year, 11,000 an hour
