Sai Wan Ho Dead Dolphin Turns Out To Be Dwarf or Pygmy Sperm Whale

The dead dolphin I posted about yesterday has been reclassified as either a dearf or Pygmy sperm whale by AFCD and Ocean Park Conservation Fund staff. The two-metre-long decomposing whale was found a few metres from the marine police base at Tai Hong Street in Sai Wan Ho.

It is believed it was a male dwarf sperm whale, but a genetic test is needed to confirm its species. The other possibility is its relative, the pygmy sperm whale. Both species are rare in local waters.
Dwarf sperm whales and pygmy sperm whales are extremely similar and usually indistinguishable when spotted at sea. They are widely distributed in tropical and temperate zones of all the world’s oceans.

The first and only recorded local sighting of a dwarf sperm whale was in 1991. There were four previous local discoveries of pygmy sperm whales, with the most recent in 2014.
