traditionally, a reptile is any amniote who belongs to the reptilia. they're generally defined as being "a group of tetrapods with an ectothermic ('cold-blooded') metabolism and amniotic development". however, dinosaurs, and therefore birds, do not fit all of these requirements, and birds are currently excluded from the traditional classification of a reptile. birds are dinosaurs, and as such, cladistically (the type of classifying organisms based on evolutionary relationships), are reptiles. reptiles are members of the group sauropsida, which includes all reptiles and their closest (now extinct) non-reptilian relatives.
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.
Fish, birds, reptiles, dogs, and mammals are all similar in one way. they all have a backbone. ~ann :]
Snakes belong to the group of animals known as reptiles.
Lizards belong to the animal group called reptiles.
both the climates of a tropical rainforest and a desert are, well, hot! They can both be humid, and are very deadly if you don't have any water. They are both found near the equator, which means the sun is out a lot longer. The only difference between the two is that the rainforest rains more, so more plants can grow than in a desert.

Becase the word 'Dinosaur' means terrible lizard.
