Crocodilians, of which there are 23
species, are found in 91
countries of the world and are divided into three families: Alligatoridae (alligators and caimans), Crocodylidae
(crocodiles), and Gavialidae (Gharials). All crocodilians are carnivores, feeding on a
variety of carrion and live prey. The
crocodiles have buccal, salt-secreting glands, which
allow them to live in brackish environments and tolerate seawater for periods
of time.
The American Alligator is found in
freshwater lakes, rivers, swamps, and occasionally brackish water in North
America from the Atlantic coastal plain of the Carolinas
south to southern Florida and
west on the Gulf coastal plain to south Texas. They can attain weights over 600
pounds and measure as much as 19 feet in length. Despite their large size and short legs, they
can run up to 30 M.P.H. for a short distance.
The American Crocodile inhabits freshwater
rivers and lakes and brackish coastal habitats such as tidal estuaries,
lagoons, and mangrove swamps from southern Florida
to northern South America. They feed primarily at night on aquatic
organisms such as fish, crabs, turtles, and on birds. Their length measures between 19
and 23 feet.
Found throughout most of Africa
and Madagascar
and until recently Israel,
the Nile Crocodile inhabits rivers, lakes, freshwater
swamps, and brackish water. Fish and
other small vertebrates form the greatest part of their diet, but as adults,
they can take antelope, buffalo, young hippos, and large cats. Nile Crocodiles reportedly reach over 19
feet in length and have a confirmed reputation as man-eaters.
The largest living crocodile of them all and
largest living reptile on earth is the Saltwater Crocodile, which has been
confirmed to reach 20.7 feet and weigh over 1.5 tons. Salties, as they
are called, are found from coastal east India
to Southeast Asia and southeast through the Indonesian
Islands to Papua,
New Guinea, and northern Australia. They inhabit brackish water areas of
coastlines and river mouths, freshwater rivers, billabongs, and swamps. Having a high tolerance of salinity has
enabled the saltie to travel long distances by sea to
populate islands. Feeding on
crustaceans, turtles, monitor lizards, snakes, fish, and birds, they
occasionally take buffalo, domestic livestock, wild boar, and monkeys. They also have a reputation as a man-eater.
Most crocodilians lay their eggs in holes in
sand banks where the sun will incubate them or in mounds they build out of
vegetation and mud, which act as compost piles and produce heat to incubate the
eggs. Most crocodilian females are
extraordinary parents. After laying
their eggs they stay close by to guard the nest against predators. When the
eggs are ready to hatch, the young start chirping, which
signals the female to dig them up. Gently she takes each one in her dangerously
toothy mouth and transports them safely to the water. The young stay close to and are guarded by
the female for up to two years.
Just as the eggs and young of the
crocodilians are under impressive, toothy watchcare,
more so are those who serve Christ under His mighty watchcare. “Those who follow Christ are ever safe under
His watchcare.
Angels that excel in strength are sent from Heaven to protect them. The wicked one cannot break through the guard
which God has stationed about His people.”
The Great Controversy, 517. “How graciously and tenderly our heavenly
Father deals with His children! He
preserves them from a thousand dangers to them unseen and guards them from the
subtle arts of Satan, lest they should be destroyed.” Testimonies, vol. 3,
373.
