| porpoise mouth, country joe and the fish |
 |
The white ducks fly on past the sun,
Their wings flash silver at the moon.
While waters rush down the mountain tongue
My organs play a circus tune.
I dance to the wonder of your feet
And sing to the joy of your knees.
The cold white dress on the mountain breast
Paints the frozen trees.
The maple plants patterns in the sky
Its leaves to kiss the wind
While scores of glittering bugs and flies
Dance polkas on her limbs.
I whistle symphonies of your face
And laugh for your hair so fine.
In startled greens of playground grass
A child jumps rope to rhyme.
Reeds and brass, the marching drums
Make a joyous sound
Trees bend low with nuts and plums
Then fall to find the ground.
I hunger for your porpoise mouth
And stand erect for love.
The sun burns up the winter sky
And all the earth is love. Tags : knees feet paintings plug ins |

VIEWERS NOTE I Slowed down a few frames so
you can see them better but I did not speed
anything up! They really do swim that fast!

Dall's Porpoise range
Dall's Porpoise (Phocoenoides dalli) is a
species of porpoise that came to worldwide
attention in the 1970s. It was disclosed for
the first time to the public that salmon
fishing trawls were killing thousands of
Dall's Porpoise and other cetaceans each year
by accidentally capturing them in their nets.
The Dall's Porpoise is the only member of the
Phocoenoides genus. It was named after
American naturalist W.H. Dall.
The unique body shape of the Dall's Porpoise
makes it easily distinguishable from other
cetacean species. The animal has a very thick
body and a small head. The colouration is
rather like that of an Orca— the main body
of the porpoise is very dark grey to black
with very demarcated white patches on the
flank that begin some way behind the
flippers, which are small and close to the
head. The dorsal fin is set just back from
the middle of the back and sits up erect. The
upper part of the dorsal fin has a white to
light grey "frosting". The fluke has a
similar frosting. The adult fluke curves back
towards the body of the animal, which is
another distinguishing feature. It is larger
than other porpoises, growing up to 230 cm in
length and weighing between 130 and 200 kg.
Dall's Porpoises live for up to 15 years.
Population and distribution
Two consistent and well-defined colour
morphs— the dalli-type morph and the
truei-type morph have been identified. The
dalli-type is more widespread, ranging across
the north Pacific Ocean from southern
California to southern Japan (including the
Sea of Japan in the south up to the Bering
Sea in the north). The truei type is more
restricted, occupying a smaller area of the
northwest Pacific north and east of Japan.
The species differs from other porpoises in
that it prefers deep water and the open
ocean. It may come closer to land. If it
does, it typically stays close to deep-water
canyons. The population is believed to be
common in most of its range and although no
precise estimates exist (surveying is
hampered by the porpoises' propensity for
approaching boats), the global population
numbers in at least the hundreds of
thousands. (See also 'conservation' below).
The greatest concentration is perhaps in the
Sea of Okhotsk.
Behavior
Dall's Porpoises are hugely active creatures.
They will often zigzag around at great speed
on or just below the surface of the water
creating a spray called a "rooster tail".
They may appear and disappear quite suddenly.
The fastest of all small cetaceans, Dall's
Porpoises can swim at up to 55 km/h, almost
as fast as the Orca. The porpoises will
approach boats and will bow- and stern-ride,
but may lose interest, unless the boat is
traveling quickly.
Dall's Porpoises appear in small groups
(about 2-- 10 in number). The groups appear
not to be tight knit and may aggregate
together at good feeding grounds. On very
rare occasions a thousand or more individual
may be seen at the same time. They feed on a
variety of fish and cephalopods. Shoals of
fish such as herring, anchovies and mackerel
are common meals.
[edit] Hybrids
Baird et al (1998) determined through DNA
sequencing that a fetus found in British
Columbia was an intergeneric hybrid of a
Dall's Porpoise and a Harbour Porpoise. This
hybrid may not be rare— it may describe the
origins of some atypically coloured
individuals that otherwise appear to be
Dall's Porpoises spotted off the coast of
Vancouver Island.
[edit] Conservation
Many Dall's Porpoises are killed each year as
bycatch in fishing nets. A serious cause of
concern is the hunting of Dall's Porpoises by
harpoon by Japanese hunters. The number of
porpoise killed each year rose dramatically
following the moratoria on hunting larger
cetaceans introduced in the mid-1980s. 1988
saw the greatest number, 40,000, killed. A
quota of 18,000 individuals per year is now
in operation. However, concern remains that
this is sufficient to deplete populations in
the western Pacific. Tags : alaska dall's cetacean sea shepherd porpoise green earth eagle environment ecology wildlife marine mammal windham666 |
