The
region of Central America also includes the territory of the West Indies
stretching from the peninsula of Florida as far as the mouth of the Orinoco and
the island group of the Greater Antilles. Central America is certainly
interesting from the ichthyological point of view, for here lies borderline
along which fish typical of both South and North America are living side by
side. Mexico with the Californian peninsula in the northwest and Yucatan in the
east is a predominantly mountainous country with a large number of still active
volcanoes. The coastal region of Mexico is mostly covered with mangrove swamps
leading to stretches of savannas and towards the south and southeast, jungles
overgrow the eastern slopes of the mountains. The mountainous character of the
region gives a steep gradient.
FISH
in these areas:
Among those
having a structure characteristic of Central American fish is first and
foremost the family Poeciliidae, also the family Cyprinodonidae. Many species
belonging to these families are not only much-sought-after aquarium fish but
also useful acids in fighting malaria because they destroy mosquito larvae.
As to North
America, it is the western Californian cost and also lowlands bordering the
eastern shores of Texas up to south Carolina that have aroused the aquarists
attention. In the state of Luisiana, the river Mississippi flows into the
Appalachian Gulf. This is the home of predatory fish of the family
Lepisosteidea (gars).These are often on view in large public aquarium. The
nature of Florida is especially noteworthy and in south is the Everglades
National Park. Here the climate, considerably influenced by the Gulf Stream,
has contributed to the rise of a naturally tropical scenery. Streams and river
flow through groves of royal palms, forming many swamps and pools, and there is
both fresh water and salt water harboring a rich ichthyofauna, e.g. Sunfish of
family Cetrarchidae.
