Mammals

Mammals have gone through many stages of development since primitive times. There is one thing that primitive mammals and the mammals of today are not able to do without the help of in vitro, and that is to live in an external environment like those environments of reptile eggs.

The only mammals that can fly are the bats, but there are many more than 20 kinds of bats.

they get it from the things they eat

The Leopard is the only natural predator (other than man) of the Okapi. They live in the same environment so it's part of the rain forest ecosystem.

The full form of JCB is John Cyril Bamford.

Sadly, it has been baby seals, which have pure white fur when they are young.

in houses,garages sheds or garages.also mexican free tailed bats and big brown bats

All mammals are vertebrates because they have a spine and spinal cord, and an internal skeleton. They belong to the Phylum Chordata.

Mammals, birds, fish, reptiles and amphibians are all vertebrates.

North America. US and Canada.

I'm not sure what a "group" is, exactly. They're in order Soricomorpha (along with the shrews... soricomorphameans "shrew-form"), family Talpidae (the Latin for mole is talpa, which is also the name of one of the several genera of moles).

right auricle, right ventricle, left auricle, left ventricle,

Breastfeeding is a defining characteristic of mammals -- so yes, all mammals breastfeed.

No flies are mammals.

No. Sea otters are found only in the northwestern Pacific. The river otter is found in North Carolina.

A Swordfish is not a mammal.It is cold blooded,and lays eggs.

68% of animals are nocturnal, but the other 32% aren't.

Argentina does not have a national mammal. The national animal of Argentina is the Hornero bird species. The national motto is Argentina is En union y libertad.

All members of the weasel family (Mustelidae), and especially those in the otter subfamily (Lutrinae). There are about 17 different species of otters (subfamily Lutrinae) in about seven genera, but the sea otter is the only member of genus Enhydra (species Enhydra lutris).

Nutria do not hibernate

A ruminant is an herbivorous mammal that has two stomachs. After chewing food, usually grass, they swallow it and it ferments in the first stomach. Then they regurgitate the food, which is now called cud, and chew it a second time, before swallowing it again, at which point the cud moves to the second stomach, where digestion continues. Most ruminants belong to the order Ruminantia, but not all of them do.

The only mammals which lay eggs are the monotremes. These include the platypus and the two species of echidna, the short-beaked echidna of Australia and the long-beaked echidna of New Guinea.

In the case of the platypus, the eggs are about 11 - 15 mm in size, or about the size of a grape. Interestingly, only the left ovary is functional. Also, while the mother produces milk, she does not have teats.

The echidna lays eggs which are about the same size.

its just like saying how does a thicker wooly jumper keep you warm there is not really any other way to explain it

Approximately 5,060. An exact value cannot be given because there are so many species that one person regards as a full species while another person regards as a subspecies.
