It may have been the slowest chase ever when a tortoise attempted to run down a television presenter who interrupted it having sex with its mate . Paul Rose - who hosts National Geographic's Pristine Seas - was on Assumption Island , north of Madagascar , when he heard an animal call , which he described as a 'blowing sound ' . As he walked towards the strange noise , it soon became apparent Rose and his cameraman had stumbled upon a male and female tortoise mating . Scroll down for video . Television host Paul Rose was chased by a male tortoise after he interrupted it mating with a female tortoise . The pair were more than 180 metres from where the presenter initially heard the noise . As Rose and his cameraman stop and try to observe the ritual , the giant tortoises stop mating . The presenter said he did not know whether or not they had stopped because of their close proximity or they had finished . The animals are seen touching noses as Rose and his cameraman watch from behind bushes . He was on Assumption Island - north of Madagascar - when the incident happened during filming . Rose and his cameraman were there taping for his National Geographic show , Pristine Seas . The host heard a 'blowing sound ' while he was walking the island and went towards , discovering the tortoises . Almost immediately the male tortoise spots them and slowly begins to turn himself around , pointing himself in the direction of the television crew . The animal then starts to make its way towards them , with as much gusto as it can muster . Rose is heard telling his cameraman , 'Do n't move ' , as it becomes apparent the tortoise is after them . As the reptile gets closer and closer to the camera , he shows no sign of stopping and so the cameraman jumps back . What ensues is a very low speed chase where the tortoise tries to defend his territory and take a bite out of Rose . The male tortoise slowly turned around to start running after the pair who were startled by the move . Humouring the reptile , Rose continued to slowly back away from it instead of running , observing its behaviour . Rose said it was the male tortoise 's way of protecting his territory and getting him away from the female . Later , the host said the tortoise had ended up chasing them for about 365 metres in a circle . 'This is the male saying , `` Hey I think you 've interrupted my mating session '' , ' Rose told the audience as the tortoise inches closer . 'You ca n't blame him he 's in the bushes over there mating on this beautiful , private island and I pitch up to take a look . ' Rose continued to humour the tortoise instead of running away . He said it was completely relentless in his pursuit , chasing them around in a 365-metre-loop .
