AMAZING footage captured by a passenger on a CalMac ferry off the Scottish coast shows dozens of dolphins leaping out from the ocean.

Henry Orr captured the wonderful clip of the school of dolphins while sailing on MV Coruisk travelling from Armadale, Isle of Skye, to Mallaig, in the Highlands.

The short video shows dozens of dolphins leaping out from the ocean before they dive underwater as they cross the path of the ferry.

The footage, which was shot on Friday morning September 6, clearly shows around 30 dolphins breaking the surface of the water.

There are more than 20 aquatic mammal species which can be seen in Scottish waters.

Four species of dolphin are commonly spotted from the Scottish coasts which include bottlenose, white-beaked, Risso's, and the common dolphin.

Harbour porpoises, which are commonly confused for dolphins, are also commonly found in Scotland.
