Pygmy and Dwarf Whales in Hawaii
PYGMY KILLER WHALE (Feresa attenuata): Pygmy killer whales though rarely seen overall, have been
observed several times off our lee shore
of Oahu. Through photo id's taken here, they seem to be
"regular" residents.
In areas where they are more frequently sighted, such at the Hawai'ian Islands, herds contain up to 50 individuals and on rare occasions a few hundred.
When a number of Pygmy Killers were brought into captivity in Hawaii and South Africa they were extremely aggressive—even killing one another. Let's keep them wild, shall we?
At the water's surface, pygmy killer whales can be quite acrobatic, leaping, spy hopping, tail slapping, and occasionally bowriding. More frequently they are seen resting- or 'logging' - when a group floats at the surface of the water, each animal still, rather like logs!

PYGMY SPERM WHALE (Kogia breviceps):
Dwarf and Pygmy Sperm Whale
DWARF SPERM WHALE (Kogia sima): (2005) Dr. Robin Baird reports that dwarf
sperm whales are the sixth most
commonly sighted odontocete around
the main Hawaiian islands. This species’
small size, tendency to avoid vessels,
and deep-diving habits, make them finding them a true treasure.
Sighting Notes: Similar in appearance to the pygmy sperm whale, but has a larger dorsal fin, generally set nearer the middle of the back. Also, the dwarf sperm whale’s blowhole is positioned further forward.
The dwarf sperm whale has a shark-like profile (but with a more pointed snout than the pygmy sperm whale), gray and white countershading, and a light pigment block resembling a shark's gill slit on the side of its head. Generally, a pair of short grooves similar to those in beaked whales is present on the 
throat. It has contains spermaceti in its melon.
Adults of this species are up to 2.7 m long and may weigh up to 272 kg. Length at birth is about 1 m.
Group sizes tend to be small, most often less than five individuals (although groups of up to 10 have been recorded). This species, like the pygmy sperm whale, is shy and undemonstrative when observed at sea. They often drift motionless at the surface. When startled, dwarf sperm whales may leave a large rust-colored cloud of fecal material behind as they dive. In at least one area, there appears to be a calving peak in summer.
Our wildlife tours focus on education and conservation with
encounters conducted in the best interest of
both humans and wildlife. We model admiration and deep respect for
these wonderful mammals.
