What is the advantage of mammals to reptiles?

With few exceptions (eg: alligators, etc.) reptiles are on their own when they are born. They receive no food or protection from the parents. Mammals, however, provide their young with milk as well as protection from predators and severe weather. They also teach their young survival skills they will need as adults.

What is the fastest speed recorded for a mammal?

Cheetahs are the fastest mammals. They can run at an average speed of around 70 mph but can only sustain this for short distances.

There are other animals (like the red tail swift and peregrine falcon) which are faster.

The tiger beetle may be the fastest relative to its body size.

Are female animals more deadly than male animals?

It depends on the species. In some species, females may be more aggressive or possess venomous characteristics for various reasons such as protecting offspring. In other species, males may exhibit more dangerous behaviors as part of mating rituals or defending territories. Ultimately, it varies among different types of animals.

Mammals that retain their young within the body of the mother for a long period of time are called?

Placental mammals retain their young within the body of the mother for a long period of time. Humans, dogs, bears, and mice are all examples of placental mammals.

Mammals which do not retain their young for a long period of time are marsupials, all of which have short gestation periods (e.g. kangaroos, koalas, Tasmanian devils, wombats, etc) and monotremes (platypuses and echidnas), which are egg-laying mammals.

Most baby animals (mammals, that is) drink the mother's milk untill they can fend for themselves.

What is the largest mammal population other than humans?

The largest mammal population other than humans is the domestic cattle, with an estimated population of over 1.4 billion worldwide.

Mammals that complete development out side of the body of the mother are called?

Mammals that complete development outside of the body of the mother are called monotremes, specifically referring to egg-laying mammals such as the platypus and echidna.

What is the life span of a groundhog?

Two to fourteen (2 to 14) years is the lifespan of a groundhog. The range of the animal in question (Marmota monax) responds to the variety of cultivated and wild habitats in which woodchucks live. Whistling pigs will live as long as 6 years in the wild and 9+ years in captivity.

Do mammals eat insects?

Any egg-laying animal is known as oviparous.

Egg-laying mammals are called monotremes. They include just the platypus and echidna.

What evolutionary change allowed for the great adaptive radiation of mammals?

A number of phylogenic novelties like endothermy with separated pulmonary and systemic circulatory systems (4 chamber hearts), and expanded cardiac output to handle the blood volume and support the high metabolic rates. Dental differentiation with 4 types of rooted teeth had combined with improved digestion to produce the metabolic base for an endothermic phylum able to rapidly expand once the opportunity was available. Until the niches opened with the last great extinction event the basic mammals would never have been able to compete against animals already highly adapted to their niches. The KT extinction allowed mammals to undergo the adaptive specializations needed to diversify into the range of modern species

What is the difference between marsupials and placental mammals?

Marsupials give birth to relatively undeveloped young that continue to develop in a pouch, while placental mammals have young that fully develop within the mother's uterus connected by a placenta. Placental mammals have longer gestation periods and typically have more complex reproductive systems compared to marsupials.

What is the largest tree-living mammal in the world?

Why do humans have a menstrual cycle while most other mammals have an estrous cycle?

Most mammals have estrous cycles while humans have menstrual cycles because when the uterine lining breaks down in humans, it needs to escape the body while in other mammals it is absorbed back into the body instead of flowing out of the body as menses.

Most mammals feel a great desire to have sex whenever they are fertile or when they are in the presence of a fertile male. But for humans, we could have the desire to have sex in any part of the month. Female humans tend to feel an even greater desire for sex during their period.
