Location
This site lies on the east side of the South Male’ Atoll, outside of
the reef. To be more exact, this is the south side of the channel mouth.
Nearby islands are Losfushi, Guraidhoo and Kandooma. The reef top drops
from ten metres (33 feet) to 30 metres (100feet) and more; there are
grottoes and projections just about everywhere. The edges of the channel
drop down to a depth of 30 metres (100 feet). Large isolated coral blocks
grow, from the scarp of the reef upward.
Dives
At Guraidhoo Corner only drift dives are possible. It is therefore
necessary to be quite an experienced diver on the reef; all the more so
because there are powerful vertical currents all around the site at
certain hours of the day. The direction of the principal horizontal
current is towards the interior of the atoll. At the edge of the channel,
which is also the deepest point, one comes drifting along the reef. The
dive comes to an end along the wall of the channel or at the edge of the
reef.
Life Forms
Because of its location outside of the reef, and because of the water
movements and the topography, this place is destined to be the home of
larger fish.
On the edges of the channel, which is to say, at depths ranging from 25 to
30 metres (80 to 100 feet), the best chances are that one will be able to
observe a great many grey reef sharks (Carcharthinus amblyrhynochos) and
the local school of eagle rays (Aetobatus narinari). The latter tend to
swim in the open ocean, at a considerable distance from the seabed. In
this same spot large hammerhead sharks (Sphyrna lewini), whale sharks (Rincodon
typus) and sailfish (istiophorus platypterus) have been sighted
frequently. Guraidhoo corner is also home to large schools of oriental
sweetlips (Plectorhyncus orientalis), bannerfish (Heniochus diphreutes),
and large black-and-white striped snappers (Macolor niger). And of course
the large and friendly humphead wrasses (Cheilinus undulatus) are ever
present.
Respect for the Environment
While skirting the reef, especially at the beginning, it is fairly easy to
maintain an adequate distance from the coral. Greater attention is
required when moving away from the edges of the reef. Indeed the reef,
which presents fewer and fewer jagged edges, is literally covered with
blocks of coral of considerable length and countless branches of acropora.
Photography
The photographer should prepare in advance to take photographs against the
light of a school of fish, and a school of eagle rays. The focal lengths,
from 20- to 50-millimetres, are perfect for this purpose.
Suggested composition: In the presence of clear waters and moderate
currents, one should attempt to move out to open water, beneath the school
of eagle rays.
These animals, shot in sharp relief against the light, will make for a
rare and spectacular photograph.

At
times, in deep waters, it is possible to encounter elegant specimens of
the hammerhead shark (Sphyrna lewini), easily recognized by the
unmistakable silhouette of its head.
