A water aerobics class at a holiday park in Australia had to be postponed after a 5ft crocodile entered the pool.Workers at the Howard Springs Holiday Park, on the outskirts of Darwin, found the crocodile as they scooped out leaves from the pool to prepare it for the class."We went down like normal to check the pool out because Tuesdays and Thursdays the local ladies of Howard Springs do their water aerobics," park manager Geoff Thompson said.A government ranger was summoned to remove the visitor, which was identified as a freshwater crocodile, capable of giving a nasty bite but rarely fatal to humans."The crocodile gave one of the rangers a bit of a run-around, having to chase it around the pool," said NT Parks and Wildlife senior ranger Tom Nichols."The crocodile did not have any markings so we believe it to be a wild animal.""While we can't be sure how it got there, it's likely it came through the swamps that join up from the Howard River."The ranger managed to capture and remove it with a scoop net."The ladies did eventually get their aerobics class: "They were all there waiting for the ranger to collect it and once he got it out of the water they started their aerobics," Mr Thompson added.Source: orange news
