Befriending a wild animal will make you a better human – here’s why | Kate Ahmad

If you return to the same spot often enough, you'll get to know the regulars

The movie adaptation of Tim Winton's novel Blueback is out this week. It focuses on a friendship with a big friendly fish - the blue groper; and the powerful response to humans threatening the animal. As with My Octopus Teacher, it's a highly emotive story, and seen by most people as unusual or unique. Because humans only befriend domestic animals such as cats and dogs. Or do they?

Let's start with the blue groper. This is a charismatic Australian native, with many interesting characteristics. They are protogynous hermaphrodites, starting life as juveniles with the potential to be male or female; and always starting as green-coloured females. The dominant male has a harem and, if he dies, the largest female will become male and adopt the striking blue hue which gives the fish its name. These fish can live up to 70 years and are the state emblem of New South Wales.
