  • This was the cooperative bubble net feeding group of 5 whales that regularly frequented the Morris Reef and I had many close encounters with. This photo clearly illustrates the structure and function of the baleen plates hanging from the roof of the whales’ mouth: they are smooth on the outside and frayed and bristly on the inside, thus creating a dense mat of coarse hairs to prevent any prey from escaping. The clearly defined palette in the roof of the mouth is also visible as is the common, distinctive pink “moustache” marking on the snout.

  • This photo illustrates the power of the whales when they surge to the surface. Their gaping jaws, scooping up hundreds of litres of sea water and fish, must exert a tremendous amount of drag. Some of the herring they were pursuing can be see flying through the air to escape their open mouths.

  • It seemed like there was an ever-increasing number of pleasure boats every year from the early days when sometimes I was blissfully alone with the whales all day. There was an increasing number of whale-watching boats as well as research boats; on one occasion i witnessed twenty different boats surrounding a pod of bubble netting whales. Most of the time the whales just continued their behaviour uninterrupted, but sometimes I witnessed them aborting their lunging and moving away to get away from a particularly noisy and intrusive boat, which included a research boat on one occasion.
