those occasions when they actually stir their bones to go someplace, they pole rafts from
island to island. During low tide, they can wade most of the way.
We set up our base in the tropics, well beyond their normal range, and hiked south
during the late summer. We made contact with a few individuals and small packs during
our month-long trek but didn't join a family until we reached the southern mountains.
The Plathys aren't too interesting during the warm months, except for the short mating
season. Mostly they loll around, conserving energy, living off the meat killed during the
thaw, which they smoke and store in covered holes. When the meat gets too old, or starts
running out, they do bestir themselves to fish, which takes little enough energy. The tides
are rather high in summer and fall, and all they have to do is stake down nets in the right
spots during high tide. The tide recedes and leaves behind flopping silver bounty. They
grumble and joke about the taste of it, though.
They accepted our presence without question, placidly sharing their food and shelter as
they would with any wayfaring member of another native family. They couldn't have
mistaken us for natives, though. The smallest adult Plathy weighs twice as much as our
largest. They stand about two and a half meters high and span about a meter and a half
across the shoulders. Their heads are more conical than square, with huge powerful jaws: a
mouth that runs almost ear to ear. Their eyes are set low, and they have mucous-membrane
slits in place of external ears and noses. They are covered with sparse silky fur, which
coarsens into thick hair on their heads, shoulders, armpits, and groins (and on the males'
backs). The females have four teats defining the corners of a rectangular slab of lactiferous
fatty tissue. The openings we thought were their vaginas are almost dorsal, with the cloacal
openings toward the front. The male genitals are completely ventral, normally hidden under
a mat of hair. (This took a bit of snooping. In all but the hottest times and mating season,
both genders wear a "modest" kilt of skin.)
We had been observing them about three weeks when the females went into estrus—
every mature female, all the same day. Their sexuality was prodigious.
Everybody shed their kilts and went into a week-long unrelenting spasm of sexual
activity. There is nothing like it among any of the sentient cultures—or animal species!—
that I have studied. To call it an orgy would be misleading and, I think, demeaning to the
Plathys. The phenomenon was more like a tropism, in plants, than any animal or human
instinct. They quite simply did not do anything else for six days.
The adults in our family numbered eighty-two males and nineteen females (the terrible
reason for the disparity would become clear in a later season), so the females were engaged
all the time, even while they slept. While one male copulated, two or three others would be
waiting their turn, prancing impatiently, masturbating, sometimes indulging in homosexual
coupling. ("Indulging" is the wrong word. There was no sense that they took pleasure in
any sexual activity; it was more like the temporary relief of a terrible pressure that quickly
built up again.) They attempted coupling with children and with the humans of my
expedition. Fortunately, for all their huge strength they are rather slow and, for all the
