SEA
FAUNA There are countless natural swimming pools in Fernando
de Noronha, so a direct contact with the varied and exotic sea
fauna of the archipelago is possible. The water around the islands
is crowded with fishes, sponges, seaweeds, shellfishes and corals,
among which the most abundant in the archipelago, the Montastrea
cavernosa.
Flat
water
In the flat water there are coloured fishes, like the "donzela
de rocas", the "sargentinho", the "coroca",
and also the morays.
Deep
water
In the deep water it is possible to find the following fishes:
"frade", "budião", "ariquita",
"piraúna" and "borboleta". The dogfishes,
the peaceful "lambaru" and the rays can be seen resting
on the ground.
Rotifer dolphins
The dolphins of the species Stenella longirostris
are known as rotifer dolphins due to the jumps with the rotating
body they use to perform outside the water. These animals
can reach a length of up to 2 m and a weight of up to 90 kg.
They have a dark grey back with median light grey strips and
a white abdomen. The pregnancy period is aprox. 10 and a half
months and the younglet is born with a length of 80 cm.
The rotifer dolphins are distributed all over the tropical
and subtropical zones of all oceans. They are aggregative
and have a sufficiently complex social behavior. They normally
move in groups of two up to many hundreds of all ages and
of both genders.

In Fernando de Noronha, the Dolphin Bay belvedere is the place
where these animals can be observed in their natural environment.
One of the most beautiful performances in the island can be seen
every day at the sunrise, when rotifer dolphin groups move to
inside the bay, where the sea is calm and protected. They use
this area for resting, reproducing and suckling and in the afternoon
they move to the high sea for eating small fishes and squids.
This is the only place in the whole Atlantic Ocean where there
are concentrations of rotifer dolphins. The prohibition of boat
traffic and diving in the creek was established in 1986 as a protection
measure, aiming the preservation of these animals. It shall be
remembered that Federal Law no. 7643 prohibits to hunt, to capture
and to annoy any species of cetaceans (dolphins, boutos and whales)
in brazilian water.
Sea
turtles
Two important beaches for "aruanã" turtle (Chelonia
mydas) spawning are protected by the National Marine Reserve
of Fernando de Noronha: the Leão Beach and the Sancho Beach..
|
From November on the turtles can be observed
in groups on the water surface, when the adult males dispute
the females, so beginning the reproduction period of this
species in the archipelago. During the rain season (December
up to May) the females come to these beaches during the night
to lay the eggs, which incubate during 50 days.
By diving in the Reserve it is possible to observe young and
adult hawksbill turtles (Eretmochelys imbricata),
a highly menaced species, as their shell is very appreciated
for making glasses, combs and bijouteries. The hawksbill turtles
use the archipelago only as a growing and feeding place. Their
origin and their migratory routes are unknown by the researchers.

The Natiopnal Center for Conservation and Sea Turtle Management
TAMAR / IBAMA watches over the females, eggs and reproduction
environments and also evaluates the turtle population in the archipelago
since 1984. These animals are protected by decree-law, which establishes
the prohibition of capture, fishing and annoying all chelonian
species in brazilian water.

TERRESTRIAL FAUNA
In the archipelago there are
natural and brought in animals:
Natural Animals
Three endemic species exist in Fernando de Noronha: the "sebito"
bird (Vireo gracilirostris), the gecko (Mabuya
maculata) and the blind worm (Amphisbaena ridleyana).
The crab (Gecarcinus lagostoma) spends his youth
and adult period in land and spawns in the sea.
Brought in animals
Some species of sylvan animals were brought to the archipelago
by man. There are the "teju" (Tupinambis teguxim),
the "mocó" (Kerodon rupestris) and
the sheeps, which are raised today in restricted areas in
order not to damage the archipelago flora. |
FOWL FAUNA
Fourty fowl species are registered in the archipelago, which
shelter the biggest reproduction colonies of seafowl among the
Tropical South Atlantic islands.
|
Native fowl
Among the protected fowl by the National Reserve the most
common is the "viuvinha" (Anous minutos).
Other great concentration fowl in the archipelago are the
great "viuvinha" (Anous stolidus), the
"trinta réis de manto negro" (Sterna
fuscata) and the white "viuvinha" (Gygis
alba).
It's also possible to find six species of pelican relative
fowl in all islands: the big white "mumbebo" (Sula
dactylatra), the brown "mumbebo" (Sula
leucogaster), the red paw "mumbebo" (Sula
sula), the "catraia" (Fregata magnificens)
and two charming species: the "rabo de junco"
with yellow beak (Phaeton lepturos) and the one
with red beak (Phaeton aethereus). In the woods
there are the "sebito" (Vireo gracilirostris),
an insectivorous and frugivorous bird, which became already
endemic, the "cucuruta" (Elaenia spectabilis
reidleyana) and the "arribaçã"
(Zenaida auriculata noronha).
|
Migratory
fowl
There is a fowl group that visit the Reserve: it's the long distance
migratory fowl, generally proceeding from the north hemisphere.
This fowl arrives for resting and feeding purposes. They are twelve
species of "maçaricos" and "batuíras",
from which the most common is the "vira pedra" (Arenaria
interpress).
| Some
data |
| .: The only existing "pardela-pequena"
(Puffinus assimilis) reproduction record is from
the archipelago. |
| .: The "rabo de junco"
with red beak (Phaethon aethereus) is 1 meter long
and 40 cm is the length of its tail. |
| .: The "rabo de junco
with orange beak (Phaethon lepturus) and the "atobá"
(Sula dactylatra) were used as food for the prisoners
between 1870 and 1942. |
| .: In June 1987, 10.630 "viuvinha
negra" (Anous tenuirostres) nests were computed. |
| .: The "cucuruta"
(Vireo glacilirostris) and the "sebito"
(Elaenia spectabilis ridleyana) are endemic species. |
