Mammals
The world is home to 4260 named species of mammals. Mammals, or Mammalia are a class in the Phylum Chordata and the Subphylum Vertebrata. An animal is a mammal if, providing it is female, it can produce milk to feed its young.

Which mammals begin with the letter V?
Jabalis, jackals, jagla, jaguarondi, jaguars, javelinas, jentinkias, jerboas, jinja-makas, juparas and juscelinomys.
Is a mollusk closest to a reptile or a mammal or amphibian or fish?
The mollusk phyllum (which includes snails, slugs, octupus, squid and some other animals) are more like related to fish.
Both groups live in or have to stay close to water (notice how snails/slugs dry out if they get in the sun too long). Mollusk are all invertebrate animals (no backbone), while today's fish are indeed vertebrates. Some of the jawless fish (like the Hagfish or the Lamrey Eel) have a very flexible vertebrate that would almost appear as if they didn't have one if you were to grab them.
Why do mammals produce a low number of offspring?
This question includes an assumption : that mammals don't lay eggs. Well, some do.
Mammals are distinguished from other creatures by two characteristics, which are found in all mammals and no non-mammals. These are the mammalian ear, which includes three tiny bones - the hammer, the anvil and the stirrup, and the nourishment of their offspring by mothers' milk. There are three subdivisions of mammals :-
- Monotremata. Only three species, the duck-billed platypus and two echidnas. All lay eggs.
- Marsupialia. These give birth to live young, but in a very small and un-developed state. The young marsupial exits the vagina and crawls up the mother's belly. It finds, and crawls into, a pouch at the top of the belly. This pouch shelters and protects the young marsupial; it also contains a patch of special skin which exudes milk when it is licked. The youngster completes its development safe and snug in the pouch, sometimes for many months. There are many species of marsupials, of which the best known are probably the kangaroo and the koala. The only marsupial found outside Australia is the American opossum.
- Eutheria. Easily the largest group of mammals, they are often called the 'true mammals'. This description may have come about because early taxonomists had never seen a marsupial, never heard of a monotreme. They thought that the distinguishing mark of a mammal was nipples (aka teats). Non-eutherian mammals don't have these, but they are mammals nonetheless.
It should be noted that every mammalian offspringoriginates from an egg. The difference between the types of mammal comes from whether the embryo develops outside its mother's body (monotremes), develops fully inside its mother's body (eutheria) or develops partly inside mother's body and partly in her pouch (marsupials).
.
As to why mammals gave up laying eggs, this is still a mystery. The beginnings of an answer may lie in the fact that evolution is combination of chance and choice. Mutations are largely random, albeit that they usually involve tiny cumulative changes to what went before. Selection is both choice and chance; mutations that give some kind of survival advantage, or sometimes just reproductive advantage, will tend to be favoured. Whether any change is advantageous may depend on the conditions of climate, food supply or competition of other animals at the time of the mutation. It does fairly shriek at us that the rise of monotremes and marsupials occurred before Australia separated from other continents, but eutheria appeared after.
Note. Australia should be taken to include surrounding islands including New Guinea.
When did the last mammoth die?
The majority of mammoths went extinct by the end of the last ice, however a population of dwarf mammoth persisted on Wrangel Island in the Arctic ocean off the coast of northern Siberia until around 5,000 years ago.
Are there any home remedies to help with skunk smell removal?
If you are interested in home remedies to help get rid of the skunk smell, there are some available. The most popular and commonly used is bathing in tomato juice.
I am a mighty mammal l breathe through a blow hole on top of your head?
Aren't you a whale? Does a whale know how to write or have a computer? This is absolutely bizarre!
Which marine mammal has the longest life span?
he common green sea turtle has a lifespan of 103 on average. The sharp tail shrimp has the shortest lifespan of 13.5 hours on average. The sea sponge has a life span of 10.000 years.
That really depends on the animal.
Something like a butterfly will have:
egg stage where its waiting to hatch
the larva or Caterpillar for a butterfly
the pupa where it is in its cocoon
lastly the adult which is a butterfly for the butterfly
Something like the a mammal will have:
birth stage
juvenile stage
Adult stage
each stages time line will depend on the specific mammal.
Something like a frog
Egg stage there in their eggs
Young juvenile tadpole
Juvenile mostly frog with a tail
Adult Full fledged frog
Juvenile is separated by adult based on breeding ability, usually.
What about what was the mammal that lays eggs?
The only egg-laying mammals are those in the order Monotremata.
There are just three species of animal in this order, and they are the platypus, short-beaked echidna (both of Australia) and the long-beaked echidna (found in New Guinea).
What is the highest order of mammals that includes man apes monkeys and starts with p?
The 'family' Hominidae (or Hominids) includes: chimpanzees, gorillas, humans and orangutans.
They are all mammals. This family includes all the Great Apes and extinct human ancestors.
Primates
The genus is called "homo".
The group includes lemurs, lorises, tarsiers, old and new world monkeys--it is known as the primates. The parvorder of just men and monkeys is Catarrhini. See link for further subdivisions.

Why do porcupines live in the deciduous forest?
Not all porcupines live in deciduous forests. There are around 24 different species of porcupine ranging from Asia, Africa, America and Europe, and their habitat can be deserts, grassland or forests of any type.
What is the only venomous mammal in the world?
There is more than one venomous mammal in the world. Male platypuses have a poisonous spur (claw) on each of their back legs. The slow loris is the only primate to be venomous. It has a poisonous bite. Several species of shrews (tiny mouse-like creatures) have poisonous bites. The solendon looks like a shrew but has a long nose. The solendon has a poisonous bite.
Which mammals secrete a musky odor when frightened?
Woodchucks, ferrets, skunks, beavers, dogs, and cats are mammals who secrete a musky odor when frightened.
What mammal is the swiftest over a short distance?
The fastest terrestrial mammal over a sustained distance is the Pronghorn antelope
This is a confusing question. Mammals are animals that have hair, give birth to live young, and nurse the young with milk.
humans are vertebrate because they have a back bone.
90% of different creatures are invertebrate such as octopuses, squids,and or different insects.
10% of different creatures are vertebrate such as dogs, cats, and humans too.
What is Minnesota's state mammal?
There is no Minnesota state mammal at this time, becaue the State legislature could not pass a bill to select a mammal. There have been seveal attempts over the past twenty or so years. The white-tailed deer has been proposed at least eight times, and the Eastern timber wolf has received support at least six times, as the official Minnesota animal or mammal.
Minnesota actually doesn't have a state Mammal. They tried to make the white tailed deer our state mammal and the angry voter as our state mammal but that didn't work so Minnesota officially doesn't have a state mammal.
Which shark has the sharpest teeth?
Definitely. All do. They have many rows of sharp teeth. When one set falls out, instead of more teeth growing up and out of their gums, like our teeth, they use the next set of teeth. Otherwise, if they didn't have sharp teeth, they couldn't be carnivores.
Where do placental mammals live?
Placental mammals are mammals that give birth to fully developed live young, such as like humans, for instance. They are classed within the group of animals known as eutherians.
Dogs, cats, livestock, rodents, giraffes, rhinoceroses, etc, are all placental mammals.
This is opposed to the monotremes, which are egg-laying mammals (platypuses and echidnas) or marsupials (kangaroos, koalas, wombats, etc), which give birth to very undeveloped young that must complete their development attached to a nutrient-supplying teat, usually in the mother's pouch.
