PremierLeague-News.Com - Breaking Sport Transfer News ! Whale sharks have an extraordinary capacity to regenerate themselves after serious injuries – a function that is increasingly important as growing wildlife tourism means more collisions with boats, a new study finds.Whale sharks are the world’s biggest fish, measuring up to 18 metres in length and they are found in tropical waters.Researchers have found they can recover from lacerations and abrasions, often caused by tourist boats, in a matter of weeks.

. “We now have a better understanding of injury and healing dynamics, which can be very important for conservation management,” said Ms Womersley.Encouragingly, the researchers found that the whale sharks unique spot markings reformed over previously injured spots, which suggests they are an important feature for this species and persist even after being damaged.A study published last in the journal Nature found that 71 per cent of ocean-dwelling shark species have seen their numbers decline over the last 50 years, and highlighted the need to enforce stricter protections.“Whale sharks have been experiencing population declines globally from a variety of threats as a result of human activity. Therefore, it is imperative that we minimise human impacts on whale sharks and protect the species where it is most vulnerable, especially where human-shark interactions are high,” Ms Womersley said.The study is published in the journal Conservation Physiology.
