Keeping its head above water and its eyes on the prize, the dolphin appears to measure the height and trajectory of the jump.

A meal is dangling at least 3m overhead, held by a lobster fisherman perched on the rails of a boat off Two Rocks.

The dolphin measures its jump.

Its previous two attempts came in quick succession and they came up short - they were rushed and the dolphin seems to know it.

Nine seconds later, apparently satisfied with its estimations, it dives into the blue for another run.

The video, posted to Facebook yesterday, reaches a climax as its star makes a third and final jump for joy.

There's a pause in the action as it barrels towards the surface, then bursts out of the water, opening its mouth in anticipation.

It climbs to within centimetres of the snack and the fisherman lets it go - a hard-earned morsel for a determined dolphin.

The Department of Parks and Wildlife advises that feeding of dolphins is illegal under a notice of the Wildlife Conservation Act 1950.
