Here are two new whale watching reports from Chas Anderson at the Whale and Dolphin Company. I would love to do one of these trips someday: I tried to get on the 2017 trip but was too late and now I am kicking myself hard.
Maldives, 2016: Chas Anderson, 12 days & 12 species including Fraser’s Dolphins and Dwarf Sperm Whales.
Maldives, 2017: Chas Anderson, 12 days & 13 species including Rough-toothed Dolphins, Dwarf Sperm Whale, Pygmy Killer Whale and Deraniyagala’s Beaked Whale.
This 2012 paper from Chas is a useful summary of the 23 cetaceans known from the area, including 5 species of beaked whale. Exciting stuff!
