Terrestrial Fauna
Like for the vegetals, there is also a few number of animal
species in French Polynesia : less than 700 insects -against
50,000 in Australia- and hardly no vertebrates. Even birds, which
method of moving allows to cross the wide Pacific ocean, only count
about 120 species - 6 times less than in Australia.
Actually, it is known that islands isolation encourages the birth
of indigenous species but also emphasizes the phenomenon
of some species disappearance. Thus it is estimated that
90% of the extinct species of the world used to live on islands.
The invertabrates gather insects,
shellfish, and mollusks.
The first category includes several species of dragonflies
-eight of which are endemic, a lot of moths and some butterflies
among which the very esthetical Danaida plexippus. There
are also coleopters, bees and bumblebees, aedes mosquitoes,
spiders and scorpions.
The main shellfish are the tupa, the only terrestrial
crab which is very common on roadsides near the sea and nests
on deep holes ; the kayeu commonly called "coconut tree
crab" is actually part of the Hermit-crab family. Finally, the
wild fresh water shrimp -greatly prized for its fine flesh-
is the most famous fresh water shellfish.
The vertebrates are many times less
numerous than invertebrates.
Among the main fresh water species we can find eels, that
are the most widly spread family. Reptiles includes 4 gecko species
and 3 lizard species usely called "margouillats" by the locals.
Mammals essentially includes porc, dogs, horses and rats. Pig
and dog were the first domestic animals known to the
Polynesians before the arrival of the Europeans, and both were
raised
for food. The Marquesas islands are famous for their horses,
probably brought from Chile. Finally, Polynesia also counts bovines
and goats, most of them living wildly.
Atolls shelter a little more than one hundred bird species and
gather more sea birds than terrestrial birds, and vice versa for
high volcanic islands. Comomn Myna is one of the most
common birds in Tahiti and her islands. Introduced in the early
XIXth century, nowadays he undangers many other species like the
Tahiti Kingfisher or the Pacific Swallow living essentially
around rivers that also attract the Little Heron. The Tahiti
petrel -which is part of the albatross family- nests on the ground,
as well as the Murphy petrel.There are several varieties
of stern among which the Great-crested stern and the White
stern that doesn't buid nests : its egg and chick have to keep on
the branch by themselves. Several varieties of pigeons are
also to be found, among other the very big Carpophage (50 cm) from
Nuku Hiva, in the Marquesas.
