The most sort after species of dolphin to watch is the Spinner Dolphin because they constantly breach. Here in Alankuda you find them not in hundreds but in thousands particularly when the 'super pod' is formed. They are the most sort after species because they continuously breach and love to bow ride.
You could spend an hour or two as they play with you and show off their aerobatic skills and not feel at all you are intruding on nature. They are such sociable mammals. Every once in a while, something happens and maybe even changes your perception of life and the world around you. Watching the playful dolphins could do just that and you will return with a greater understanding of the oceans around us and why we need to do all we can to protect it and these wonderful animals "like no other". Other species of Dolphins seen here at times are Bottlenose, Spotted, Striped, Humpback, Risso and Fraser.
The deeper waters off Alankuda and Kalpitiya coastlines are the haunt of six types of whales. The biggest of Sri Lanka’s big five can be seen surfacing from time to time and the sight of these enigmatic cetaceans is both breathtaking, spellbinding and offers a truly humbling experience.
There are peaks in the movement of whales between November and December and again between March and April. Sperm Whales are most common, other Whales you could see include the Blue, Minke, Melon-Headed, Pilot, Brydes and Dwarf Sperm whales. The months of November and April are the best times for whale watching in Alankuda. Whales are spotted during the period from November to April but not as often as these two months which is the migration period and are seen close in shore in large numbers.
