Fast-living fish swims into record books

Queensland marine researchers say there are good reasons for the frantic lifestyle of the world’s shortest-living fish.

The Guinness Book of Records has recognised the Australian coral reef pygmy goby, which lives for about 59 days, as the fish with the shortest lifespan on the planet.

James Cook University’s David Bellwood submitted the goby for world record scrutiny.

Professor Bellwood says it spends only 21 days as an adult fish and lives a fast life mainly because of predators.

“These things are being eaten, something like 8 per cent disappear every day,” he said.

“If you have got a gang of 10 of them each day pretty much you lose one of them.

“They only really get for a female three goes at it, so for a female will lay three batches of young and that’s if they manage to make it for their full life span.”
