In the past few decades, countries implemented cross-border policies to directly address the causes of bycatch, particularly for albatrosses and petrels, which have been severely affected. Bycatch kills hundreds of thousands of birds and mammals each year. The discovery came about by accident when researchers at the Centre d'études biologiques de Chizé in France were investigating bycatch in fishing lines and nets – when fishers unintentionally snare animals they weren’t trying to catch, like albatrosses. Now researchers have found that these seabirds may have promising careers in the fight against overfishing. Their body shape means they can effortlessly glide over the ocean waves, flying in some of the strongest winds on Earth. Their 3.5m wingspan is the same length as a small car and they can weigh as much as 24 puffins. They can fly 8.5 million kilometres (5.2 million miles) during their lifetimes – the equivalent of flying to the Moon and back more than 10 times. Wandering albatrosses have long been considered exceptional creatures.
