A close encounter with a wild dolphin delighted children swimming off the Busselton Jetty on Monday when they had the opportunity to swim with the mammal.
Visitor Graeme Speak captured the moment on video and said he was about a third of the way down they jetty when he saw a dolphin in suspended motion close by.
“It was completely motionless, we were looking at the dolphin and it was looking at us, it was so cool,” he said.
Mr Speak said some young girls saw the dolphin and climbed down the ladder into the water for a chance to get close to the dolphin.
“It was so beautiful, the water was so transparent, it was amazing to see little girls treading water with the dolphin which was quite timid,” he said.
Department of Biodiversity, Conservation and Attractions advised feeding any wild animals could be detrimental to their health and well-being.
Animals can become used to people and learn to take advantage of food scraps and offerings.
Although this is usually done with good intent, feeding wild animals can upset the balance of nature.
Providing a regular artificial food source can lead to too many animals living in an area, putting extra pressure on natural food sources.
The department said interacting with dolphins do not cause them harm, but swimming with the wild mammals could be seen as a threat or rattle the animal.
