Johannesburg - A surfer was bitten by a shark while surfing off Look Out Beach in Plettenberg Bay in the Western Cape late Friday afternoon, the National Sea Rescue Institute (NSRI) said.The NSRI were activated at 17:10 following reports of the incident, with a sea rescue craft, NSRI rescue swimmers, medics and ambulances services dispatched to the scene, spokesperson Craig Lambinon said in a statement."On arrival on-scene it was determined that 23-year-old Dylan Reddering, from Plettenberg Bay and currently a student at the University of Cape Town (UCT), had been rescued from the water by fellow surfers Lloyd Chapman, Adriaan Augustyn, Wotjeck Orzechowski and his son Tadj, after being bitten by a shark while surfing."Reddering suffered lacerations and bite marks on the right side of his body, his ribs, his buttocks and on his leg."The bite marks were deep and NSRI medics and Baycare paramedics initiated medical treatment, although Dylan remained calm and in good spirits and he was in a fairly stable condition," Lambinon said.He was transported to hospital for further treatment, and received medical care on en route."Once in hospital, medical staff continued with treatment and it appears that the bites have missed major organs and missed major arteries and the patient requires sutures," Lambinon said."Dylan is the son of veteran NSRI Plettenberg Bay volunteer crewman Marty Reddering. The species of shark has not been determined although it is suspected to be a 2 to 3 metre White Shark. White sharks are common to the area."Bathers and surfers were urged to be cautious in the area following the incident, particularly with the start of the winter holidays. The public were advised to preferably stay out of the water until municipal authorities advised further."Dylan has been stabilised at Plettenberg Bay Medi-Clinic and is being transferred by ER24 ambulance to Life Care Knysna Private Hospital for further medical treatment," Lambinon said.
