Whale watching staff member returns, again

“The area of western Bass Strait has a remarkably high diversity of species at this time of the year” David said. “This can mostly


be attributed to a phenomenon known as the ‘Bonney Upwelling’ which generates a high level of primary productivity. In turn, this fuels zooplankton biomass and leads to feeding opportunities for many ocean predators, from sea birds to blue whales.” The voyage documented 10 cetacean species including sperm whales, killer whales and a very rare encounter with a pod of Shepherd’s beaked whales, only the sixth confirmed sighting of this cryptic species. Forty to fifty individual pygmy blue whales were sighted during the three week voyage.
