Which has more teeth mammal or reptile?
Typically, mammals have more teeth than reptiles. Mammals generally have specialized teeth for different functions such as cutting, tearing, and grinding food. Reptiles, on the other hand, may have fewer teeth or even be toothless, depending on the species.
Are reptiles more closely related to mammals or to fishes?
Reptiles are more closely related to mammals than to fishes. Reptiles and mammals are both part of the group called amniotes, characterized by their ability to lay eggs on land. Fish, on the other hand, are a separate group with distinct evolutionary lineages from reptiles and mammals.
Why do mammals lose more heat energy than reptiles?
Mammals have higher metabolic rates than reptiles, which means they generate more heat internally. This excess heat needs to be released to maintain a stable internal temperature, so mammals lose more heat energy through mechanisms like sweating, panting, and shivering. Reptiles have lower metabolic rates and can rely on external sources of heat, like the sun, to regulate their body temperature.
What animals have molars and premolars?
Mammals are the primary group of animals that have molars and premolars. These teeth are typically found in the back of the mouth and are used for chewing and grinding food. Other vertebrates like some reptiles and fish may also have similar tooth structures, but they are more common in mammals.
How does the heart of crocodiles differ from that of other reptiles?
The heart of crocodiles has a more complex structure compared to other reptiles. It has a four-chambered heart similar to birds and mammals, allowing for efficient oxygenation of blood. This adaptation enables crocodiles to have greater endurance and performance in aquatic environments.
Which has more teeth mammal or reptile?
Typically, mammals have more teeth than reptiles. Mammals generally have specialized teeth for different functions such as cutting, tearing, and grinding food. Reptiles, on the other hand, may have fewer teeth or even be toothless, depending on the species.
Do mammals have more teeth than reptiles?
Yes, mammals have more teeth that reptiles. The land mammal with the most teeth is the Giant Armadillo (Priodontes giganteus) with as many as 100 teeth. The average range for mammals however is 20-40. Reptiles rarely have many teeth, if any at all. The crocodile has the most, with around 80 teeth at a time. It replaces as many as 3000 in its lifetime, but this is over a long period of time.
Do reptiles have flat grinding teeth?
No, reptiles typically have sharp, pointed teeth for gripping and tearing food, rather than flat grinding teeth like mammals. Some herbivorous reptiles may have more flattened teeth for crushing plant material, but they are not true grinding teeth like mammals.
How do paleontologists distinguish between fossils of mammals and reptiles?
There are a variety of features but one is the number of fenestrae in the skull. Mammals also have more differentiated teeth than reptiles. Furthermore, you can look at the gait. Mammals have a parasagittal stance, while most reptiles have a sprawled stance.
How are mammal teeth different from birds and reptiles?
Birds do not have teeth. Mammals have differentiated teeth while the teeth in the mouth of a given reptile are more or less the same except for the fangs of venomous snakes.
Are reptiles more closely related to mammals or to fishes?
