Terrain shapes and bedrock
The volcanic archipelago has its longitude in the
northwest - southeast and includes (besides the French
Mayotte) three major islands and a number of small, all
surrounded by coral reefs. At the far north-west is
Ngazidja, which is the largest of the islands. On its
southern part, Kartala, 2,361 m above sea level, rises an
active shield volcano that erupted, among other things.
1972. A plateau at a height of 610 m with thin ground cover
and straight coastline spreads northwards. The second
largest island, Nzwani, has a triangular shape and a peak of
1,595 m above sea level. The soil is fertile but strongly
eroded. The third main island, Mwali, consists of a basalt
plateau of about 310 m above sea level. with a ridge that
reaches 800 m above sea level.
The tropical islands have a dry season during May to
October, when the average temperature is 20 °C, while the
rainy season during summer, November to April, is humid and
hot, around 28 °C. Rivers are formed during the rainy
season, except at Ngazidja, where the water drops into the
Plant-and animal life
The islands' original vegetation was a mixture of forests
and grasslands. Practically all forest is gone today, and
large parts of the area are cultivated.
The fauna is poor in species and closely related to the
Malagasy but has both African and Asian features. Here you
will find two species of lemurs, mungomaki (Lemur macaco)
and mayotemaki (Lemur fulvus mayottensis).
Comorodrongo (Dicrurus fuscipennis) and mayotted
drongo (Dicrurus waldeni) are examples of endemic
birds. Lately, many mammals and birds have been introduced
to humans. Around most of the islands are mangrove forests
and coral reefs. In the sea outside the Comoros lives the
striking tailed tail fish.
