Why do reptiles need to eat less than mammals?
Reptiles are cold-blooded, so their metabolic rate can drop right down which means that they use less energy which in turn means they don't need to eat that much.

How are platypus similar to reptiles and mammals?

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.
What is the difference and similarities between warm and cold blooded animalsWhat are examples of each?
Mammals and birds are "warm" blooded, reptiles and fish are "cold" blooded. Proper terminology would be that mammals operate at a constant temperature, whereas reptiles cool off in the cold. Structurally they are all more or less alike, but the enzymes of "cold" blooded animals can operate over a much wider temperature range.
Do reptiles have lymph nodes?
No. Reptiles do not have lymph nodes as mammals do. Reptiles have lymph tissue in certain organs, particularly the spleen, but no peripheral nodes. They do have valves along the lymph perivascular areas though, sometimes called lymph "hearts", but these are not directly comparable to lymph nodes for trapping of toxins.Source: Infectious Diseases and Pathology of Reptiles By Elliott R. Jacobson"Although reptiles lack discreet lymph nodes, they do have less structured lymphoid cell aggregates within intestinal and pharyngeal mucosa."Source: Investigative Immunotoxicology By Helen Tryphonas
Why are neonates unsuitable for ready-made total parenteral nutrition?
