Large, solidly built, lizard-like reptiles, crocodilians have long flattened snouts, laterally compressed tails, and eyes, ears, and nostrils at the top of the head. They swim well and can move on land in a "high walk" and a "low walk", while smaller species are even capable of galloping. Their skin is thick and covered in non-overlapping scales. They have conical, peg-like teeth and a powerful bite. They have a four-chambered heart and, somewhat like birds, a unidirectional looping system of airflow within the lungs, but like other reptiles they are ectotherms.

The Crocodilia Crocodylia Крокодил
The Crocodilia (or Crocodylia) are an order of large, predatory, semiaquatic reptiles. They appeared 83.5 million years ago in the Late Cretaceous period (Campanian stage) and are the closest living relatives of birds, as the two groups are the only known survivors of the Archosauria. Members of the crocodilian total group, the clade Pseudosuchia, appeared about 250 million years ago in the Early Triassic period, and diversified during the Mesozoic era. The order Crocodilia includes the true crocodiles (family Crocodylidae), the alligators and caimans (family Alligatoridae), and the gharial and false gharial (family Gavialidae). Although the term 'crocodiles' is sometimes used to refer to all of these, a less ambiguous vernacular term for this group is crocodilians.

Crocodylia - Classificação e Biologia dos jacarés, crocodilos e gaviais
Os Crocodylia constituem uma linhagem dentro do grupo dos Reptilia. Por esse motivo, eles também são pertencentes ao grupo dos Amniota, os Tetrapoda que conquistaram definitivamente o ambiente terrestre. Dentro do grupo dos Crocodylia estão os jacarés, caimans, crocodilos e gaviais. Esses animais colonizaram secundariamente o ambiente aquático e são excelentes predadores. Uma das peculiaridades desse grupo é a presença do forame de Panizza, uma conexão entre as artérias aortas direita e esquerda, que permite a mistura de sangue venoso e arterial quando necessário.

The Crocodilia (or Crocodylia) are an order of large, predatory, semiaquatic reptiles. They appeared 83.5 million years ago in the Late Cretaceous period (Campanian stage) and are the closest living relatives of birds, as the two groups are the only known survivors of the Archosauria. Members of the crocodilian total group, the clade Pseudosuchia, appeared about 250 million years ago in the Early Triassic period, and diversified during the Mesozoic era. The order Crocodilia includes the true crocodiles (family Crocodylidae), the alligators and caimans (family Alligatoridae), and the gharial and false gharial (family Gavialidae). Although the term 'crocodiles' is sometimes used to refer to all of these, a less ambiguous vernacular term for this group is crocodilians.
Spelling and etymology
The group is often spelled 'Crocodylia' for consistency with the genus Crocodylus (Laurenti, 1768). The original name as published by Richard Owen in 1842 had the -i- spelling, more accurately Latinizing the Greek κροκόδειλος (crocodeilos), which means both lizard and Nile crocodile. The Greek name in turn is assumed to derive from κρόκε (kroke), shingle or pebble, and δρîλος or δρεîλος (dr(e)ilos), worm. The name may refer to the animal's habit of basking on the pebbled shores of the Nile.
Digestion
Crocodilian teeth are adapted for seizing and holding prey, and food is swallowed unchewed. The digestive tract is relatively short, as meat is a fairly simple substance to digest. The stomach is divided into two parts: a muscular gizzard that grinds food, and a digestive chamber where enzymes work on it. The stomach is more acidic than that of any other vertebrate and contains ridges for gastroliths, which play a role in the mechanical breakdown of food. Digestion takes place more quickly at higher temperatures. Crocodilians have a very low metabolic rate and consequently, low energy requirements. This allows them to survive for many months on a single large meal, digesting the food slowly. They can withstand extended fasting, living on stored fat between meals. Even recently hatched crocodiles are able to survive 58 days without food, losing 23% of their bodyweight during this time. An adult crocodile needs between a tenth and a fifth of the amount of food necessary for a lion of the same weight, and can live for half a year without eating.

Os Crocodylia constituem uma linhagem dentro do grupo dos Reptilia. Por esse motivo, eles também são pertencentes ao grupo dos Amniota, os Tetrapoda que conquistaram definitivamente o ambiente terrestre. Dentro do grupo dos Crocodylia estão os jacarés, caimans, crocodilos e gaviais. Esses animais colonizaram secundariamente o ambiente aquático e são excelentes predadores. Uma das peculiaridades desse grupo é a presença do forame de Panizza, uma conexão entre as artérias aortas direita e esquerda, que permite a mistura de sangue venoso e arterial quando necessário.

The Crocodilia (or Crocodylia) are an order of large, predatory, semiaquatic reptiles. They appeared 83.5 million years ago in the Late Cretaceous period (Campanian stage) and are the closest living relatives of birds, as the two groups are the only known survivors of the Archosauria. Members of the crocodilian total group, the clade Pseudosuchia, appeared about 250 million years ago in the Early Triassic period, and diversified during the Mesozoic era. The order Crocodilia includes the true crocodiles (family Crocodylidae), the alligators and caimans (family Alligatoridae), and the gharial and false gharial (family Gavialidae). Although the term 'crocodiles' is sometimes used to refer to all of these, a less ambiguous vernacular term for this group is crocodilians.
Spelling and etymology
The group is often spelled 'Crocodylia' for consistency with the genus Crocodylus (Laurenti, 1768). The original name as published by Richard Owen in 1842 had the -i- spelling, more accurately Latinizing the Greek κροκόδειλος (crocodeilos), which means both lizard and Nile crocodile. The Greek name in turn is assumed to derive from κρόκε (kroke), shingle or pebble, and δρîλος or δρεîλος (dr(e)ilos), worm. The name may refer to the animal's habit of basking on the pebbled shores of the Nile.
Digestion
Crocodilian teeth are adapted for seizing and holding prey, and food is swallowed unchewed. The digestive tract is relatively short, as meat is a fairly simple substance to digest. The stomach is divided into two parts: a muscular gizzard that grinds food, and a digestive chamber where enzymes work on it. The stomach is more acidic than that of any other vertebrate and contains ridges for gastroliths, which play a role in the mechanical breakdown of food. Digestion takes place more quickly at higher temperatures. Crocodilians have a very low metabolic rate and consequently, low energy requirements. This allows them to survive for many months on a single large meal, digesting the food slowly. They can withstand extended fasting, living on stored fat between meals. Even recently hatched crocodiles are able to survive 58 days without food, losing 23% of their bodyweight during this time. An adult crocodile needs between a tenth and a fifth of the amount of food necessary for a lion of the same weight, and can live for half a year without eating.
Os Crocodylia constituem uma linhagem dentro do grupo dos Reptilia. Por esse motivo, eles também são pertencentes ao grupo dos Amniota, os Tetrapoda que conquistaram definitivamente o ambiente terrestre. Dentro do grupo dos Crocodylia estão os jacarés, caimans, crocodilos e gaviais. Esses animais colonizaram secundariamente o ambiente aquático e são excelentes predadores. Uma das peculiaridades desse grupo é a presença do forame de Panizza, uma conexão entre as artérias aortas direita e esquerda, que permite a mistura de sangue venoso e arterial quando necessário.

Large, solidly built, lizard-like reptiles, crocodilians have long flattened snouts, laterally compressed tails, and eyes, ears, and nostrils at the top of the head. They swim well and can move on land in a "high walk" and a "low walk", while smaller species are even capable of galloping. Their skin is thick and covered in non-overlapping scales. They have conical, peg-like teeth and a powerful bite. They have a four-chambered heart and, somewhat like birds, a unidirectional looping system of airflow within the lungs, but like other reptiles they are ectotherms.
