what are the characteristics features of teeth in herbivores?

All animals have teeth that are adapted to eating certain types of food. For instance, herbivores, because they are plant eaters, have strong and flat molars that are made for grinding leaves and small or non-existent canine teeth.

They are only dissimilar in the enamelling. Llama incisor teeth have enamel all round, whereas alpaca incisors have enamel only on the front. As well as molars for chewing, a camelid has 6 front incisors on its lower jaw, and a hard pad on the upper jaw, similar to sheep.

Elk have other teeth, but they are made of enamel and resemble the teeth of other herbivores. Elk and walrus are the only animals in North America that have ivory tusks.

The teeth which are adapted to cutting into food are theA)incisors.

Elephants usually have 26 teeth: the incisors, known as the tusks, 12 deciduous premolars, and 12 molars. Unlike most mammals, which grow baby teeth and then replace them with a single permanent set of adult teeth, elephants are polyphyodonts that have cycles of tooth rotation throughout their lives.

The premolars and molars are together known as cheek teeth. Cattle first develop 20 temporary teeth, known also as deciduous, milk, or baby teeth. These temporary teeth eventually fall out and are replaced with 32 permanent or adult teeth as an animal matures.

Teeth consist mostly of hard, inorganic minerals like calcium. They also contain nerves, blood vessels and specialized cells. But they are not bones. Teeth don't have the regenerative powers that bones do and can't grow back together if broken.

Sheep only have front teeth in their lower jaw. You can estimate the age of a sheep by the number of teeth in its lower jaw. Sheep are born without teeth, but most have eight milk teeth by the time they are two months old.

Built for crunching and chewing, teeth mostly consist of hard, inorganic minerals like calcium. But they also contain nerves, blood vessels and specialized cells that manufacture the tooth's different parts, says Bill Gengler, a veterinary dentist and oral surgeon with the UW–Madison School of Veterinary Medicine.

What five characteristics do mammals have in common? Mammals have hair or fur; are warm-blooded; most are born alive; the young are fed milk produced by the mother's mammary glands; and they have a more complex brain than other animals. 2.

Chordates are deuterostomes with four unique characteristics which appear some time during the animal's life. These characteristics are the notochord, a dorsal, hollow nerve cord, pharyngeal slits, and a muscular postanal tail.
