Mammalians are animals that feed their babies from their breasts. :D
Of course, salt is necessary for all mammalians.
no two group of mammles can mate
Yes panthers reproduce. They reproduce just like any other mammalians.
Yes. Dogs are mammals. They are warm blooded and produce milk to feed their young.
Not recommended; ask a veterinary doctor.
Better than many mammalians, but they are subject to overheating, as canines do not perspire (the reason dogs pant on a hot day).
Do you mean mamelons- the small bumps on the incisal edge of a tooth? There is no particular age, they go away over time by attrition from eating or how the teeth occlude.
All animals with spines are vertebrates, and polar bears have spines.
Depends. If the animal is aware or capable of knowing of its existence as a sole creature, a self-sustaining creature, then I would believe so. Pigs, Dolphins, and Elephants are mammalians that are aware of their existence just to name a few , as this is noted by their proportionally large frontal lobes.
What type of "bumps on the bottom" do you mean? If its a bump on the inside of the gums situated beneath the premolars, it's known as the torus. just a bone elevation, nothing harmful. If it is at the back of the first molars, the 2nd molar teeth are erupting nothing to be cautious about. If it is on the teeth itself, usually the front ones it's called mammalians and usually it will erode during wear and tear for years to come. These bumps were just to help your adult teeth to come through. they will wear away eventually
Black and white, as in a comedy done be Sammy Davis junior and Peter Lawford.
Many facts about the Velociraptor are well known. This is mainly due to the discovery of several fossils. It lived during the Cretaceous period and became extinct about 70 to 80 million years ago. Like the other dinosaurs it is likely believed that it must have perished when a comet struck the Earth at the time.
