No, it isn't. They don't have any ability to regulate their own body temperature - they rely on an external source to raise their temperature to a suitable level.
Reptiles are cold blooded and require the atmospheric heat to regulate their internal body temperature. If the outside temperature were to decrease by 20 c the internal temperature of the reptile would decrease 20C.
Lizards and snakes are reptiles and they have no way of regulating their internal temperature. Hence they need heat to assist them to metabolize and function as a living organism.
for reptiles it is internal fertilization and they can't do external fertilization
yeah basically
All reptiles are vertebrates because they have a backbone and internal skeleton.
Reptiles are cold blooded and require the atmospheric heat to regulate their internal body temperature. If the outside temperature were to decrease by 20 c the internal temperature of the reptile would decrease 20C.
Reptiles ONLY have internal fertilization
The three Vertebrate groups that have the same temperature as their surroundings are Fish, Reptiles, and Amphibians. That means they are all cold blooded.
Gills
Dinosaurs were reptiles and like all reptiles, use internal fertilization.
VERY INTERNAL
All reptiles are internal
Snakes are reptiles, and all reptiles lay eggs. That is a basic characteristic of reptiles.
One characteristic all reptiles share is that they are all cold-blooded.
Internal fertilization
Not all organisms have the ability to maintain a constant internal temperature. Cold-blooded organisms like reptiles and amphibians need external sources like the sun to help them maintain a healthy temperature.
