1. Crocodylus porosus
One species, the marine crocodile (Crocodylus porosus) is the largest of the
crocodiles of today (the largest of which the news is 8.5 meters long and 1,700
kilos, and was caught in Queensland (Australia ) in 1957), 3 4 5 lives in both
freshwater and salty estuaries and often delves into the sea, which has allowed
it to colonize many islands of Australia and all coasts from India to Australia,
and even , often comes across the Indian Ocean and reaches East Africa, from
Somalia to Madagascar and South Africa. The marine crocodile is not the only
venture into the sea, although the one doing it more often. Thus, the Nile
crocodile (Crocodylus nyloticus) has crossed the ocean to colonize several
islands in the Indian Ocean (including Madagascar) and the American crocodile
(Crocodylus acutus) has come to swim to most Caribbean islands, and even to
the southern tip of Florida. The largest are the ocean, the Nile and the Orinoco
crocodile (Crocodylus intermedius).
The young crocodiles feed on crabs, insects and frogs. The hunt larger fish feed
on dead animals or remain on hold for hours, ready to swallow prey as
mammals and waterfowl. Cling to prey with powerful jaws and sharp teeth,
dragging it underwater to drown. Crocodiles can not chew, so that cut the dam,
shaking and despedazándola with his teeth. Grow new teeth to replace those
broken or lost. Their bite is the most powerful of the entire animal kingdom, from
about 1,800 kilos of fuerza.6
Crocodiles lives are fairly inactive as lie still for most of the day. Morning slowly
heated rivers and crocodiles often seek the warmth of the sun on the riverbank.
At night the water cools slowly so that alligators spend these hours in the river
to keep warm. Open their mouths wide helps to heat or cool the morning at
noon in the mouth are blood vessels near the skin surface, allowing heat to
pass rapidly from the blood or the environment
