Pygmy Sperm Whale (Kogia breviceps)
The Pygmy Sperm Whale is not often observed at sea since it is mainly found far away from shore. It is likely to be confused with the Dwarf Sperm Whale, in fact, they were not recognized as two separate species until 1966. When frightened, the Pygmy Sperm Whale releases a reddish brown intestinal fluid, leaving a dense cloud in the water which may work as a decoy. It is one of the smallest whales, growing up to 3,4m(11¼ft), which is not much larger than many dolphins. The Pygmy Sperm Whales are known to be solitary but they have been observed in groups consisting of up to six individuals.
