Yesterday at Lower Trestles a local videographer caught what appeared to be a possible shark sighting on camera. In the clip below, you can clearly see a large fin breach the water behind the breaking waves. There were about 25 to 30 surfers in the line-up at the time of the sighting along with a couple of children playing in the shore breaks. It was not confirmed that the mysterious fin sighting was in fact a shark. Regardless, everyone was just thankful that the marine animal did not show any interest in the surfers and swimmers in the line-up.
