Dolphins or monkeys I think. -Tori
yes mammals do use internal reproduction as they are more likely to survive longer as they are less likely to be eaten.
well birds get eating more than mammals so they help care more.
a lot of mammals live in the wetlands. here are some birds, chipmunk, squriel, and alot more too.
Lions, Tigers, Wolves and many more.
Dolphins,whales,guppy and lots more
penguins, whales, seals and lots more
Larger mammals are more likely to take a longer time to care for their young. The important correlation behind this is that more intelligent mammals take a longer time to care for their young because there are more skills that the young need to learn in order to succeed as adults. And larger mammals are somewhat more likely to be intelligent. All the smartest mammals are at least somewhat large, but the correlation between size and intelligence in mammals is not absolute and has many exceptions.
You are more likely not to live.
No, otters are mammals, and so give birth to live young.There are a few mammals that lay eggs, Platypus is one...probably what you are thinking of...there are a few more but they are not commonly known. No, otters give birth to live young.
Elephants are like humans. They have a long life expectancy like humans. Elephants in the wild are known to live an average of 50 to 70 years. Some domesticated elephants have known to live upto the age of 80 years too. They probably live the longest among all mammals (excluding humans).
Fur and a layer of fat beneath mammals skin enables mammals to live in colder environments than reptiles because the amount of fur that covers a mammal's skin varies greatly like animal that live in cold region have more fur than animal that live in warmer environments.hope this helps!!
Mammals that give birth to fully developed live young are called eutherians or placental mammals. These mammals have a complex placenta that nourishes the developing fetus during gestation, allowing them to be born at a more advanced stage of development compared to other mammals, such as marsupials. Examples of eutherians include humans, elephants, and whales.
