Marine biologists consider Mirissa & Dondra head areas deep down south as a vital path for Blue and Sperm whale migration along Sri Lanka, on their way to the Bay of Bengal from the Arabian Sea and back again. November - December and March - April has been documented as the peak season for watching these gentle giants of the Ocean as they go about their migration in search of krill, their staple diet.
The very first under water Sperm whale film in Sri Lanka has been done in the 1980’s by the marine biologists of the research vessel “The Tulip”, which also started the commercial whale watching tours in Sri Lanka. An award winning film on habits of Sperm whales “Whales weep not” was also done in Trincomalee, Sri Lanka.
The BBC documentary titled “Ocean Giants” featuring the mesmeric world of Whales and Dolphins, and the scientist’s effort to shed light on their habits and why they grow so large were filmed around Sri Lanka and according to them 30 Blue Whales were sighted in a single day! A part of the series about Blue whales was done in Sri Lanka by underwater cameramen Doug Allan and Didier Noirot for the BBC series Ocean Giants.
However Andrew's pilot film project “Whale Island”, initiative would expand while working with another whale specialist, author Philip Hoare. During their second venture into the waters off the coast of Sri Lanka, the two whale experts spotted, in spite of bad weather, groups of 25-40 whales with blows rising across the horizon. Quote “Andrew describes, "Here was a beautiful island off the subcontinent, and the entire island surrounded by Cetaceans; Blue Whales, Sperm Whales, Bryde's Whales, Orca (Killer Whales), False Killer Whales, Dwarf Sperm Whales, Spinner Dolphins, Risso's Dolphins... an extraordinary wealth of Cetaceans-based marine life."
