Crocodiles and snakes
The main differences between fish and reptiles are:fish breathe through gills and reptiles breathe through lungsFish have scales and reptiles have scaly skinFish must live in water but reptiles are terrestrial (except for turtles)
All reptiles are diapsids. Mammals (like you and I) are, in contrast, synapsids. So in that respect all reptiles are alike. However, I would not say they were all alike. Snakes are reptiles but lack limbs. Alligators are also reptiles, as are lizards. Tuatara, gavials, amphisbaenids, and tortoises each represent one of the four main modern orders of reptiles. They share some characteristics--just as you and I do, but I would not say they were all alike.
Feathers are a unique feature of birds that are not found in living reptiles. Feathers provide insulation, enable flight, and help with courtship displays and camouflage. This characteristic is one of the main distinctions between birds and living reptiles.
A reptile is a vertebrate with a backbone and skeleton. It is cold-blooded so it depends on warm temperatures to keep warm. Some will hibernate in winter. It lays leathery eggs on land and the babies look like small versions of the adults. A reptile has lungs to breathe with. Alligators and turtles are reptiles.
Some reptiles that are in danger of extinction include sea turtles, such as the Loggerhead and Leatherback turtles, as well as the Komodo dragon and various species of tortoises. The main threats to these reptiles are habitat loss, climate change, poaching, and pollution. Conservation efforts are being made to protect these species and their habitats.
Reptiles were the main vertebrates during the Mesozoic. There were dinosaurs on land and pterosaurs in the sky. There were also marine reptiles like plesiosaurs and mosasaurs.
Funny you asked. The reptiles dominated from the permian to cretaceous period. The answer is the mesozoic era. There are three geological eras: paleozoic, mesozoic and the Cenozoic. We are currently in the Holocene epoch of the quaternary period of the Cenozoic era.
what are the four main characters of reptiles
There are four main classes of animals: Mammals (Mammalia), Birds (Aves), Reptiles (Reptilia), and Fish (Chondrichthyes, Agnatha, Placodermi, Actinopterygii, Sarcopterygii).
Mesozoic is a geological era, referring to the era lasting from around 250 million years ago up til about 65 million years ago. It is also sometimes called the Age of Reptiles because dinosaurs were the main animal at the time. This particular era includes the Triassic, Jurassic, and Cretaceous periods. Mesozoic basically translates as middle life, and is the era between the Paleozoic and Cenozoic eras of the Phanerozoic Eon. The Mesozoic era is centred between two mass extinctions, the Permian-Triassic event and the Cretaceous-Poleogene event. The Permian-Triassic event was the largest mass extinction in our world's history.
Going back to the dinosaur ages, (yes they were reptiles) not very much. They are still cold blooded scaly reptiles that lay eggs. In fact the 2 main types of reptiles (snakes and lizards) have really only got 1 main difference, one has legs and one hasn't. I'll let you work out which ones which. In fact some larger snakes have got 4 lumps on their belly where legs were once in their ancestral history, or where legs will be a few million years from now.
Reptiles are cold-blooded creatures. They commonly eat insects and have dry, scaly skin. They reproduce by laying eggs and all reptiles are vertebrates.
