What are three feeding adaptations of three groups of placental mammals?

Whales, dolphins, and porpoises form one group because they can swim and get sea food.
The mammals in the carnivore group, (cats, dogs, otters, seals, ect.) are all predators because they have enlarged canine teeth.
Primates, (monkeys, apes, humans) have large brains and eyes that face forward. Also, primates have adaptations for grasping.
Hope this helps! :)

∙ 14y agoThere are many more than three ways by which scientists sort placental mammals. These include characteristics of teeth, diet, and characteristics of feet (eg claws, hooves).

What are the three main groups of mammals?
Monotremes, marsupials, and placental mammals.
What vertebrate group has three major groups egg-laying pouched and placental?
Mammals has these 3 groups .
Are all mammals marsupial?
No. Marsupials are just one of three groups of mammals. The other two are monotremes and placental mammals. The vast majority of modern mammals are placental.
Do all mammals have placenta?
no they do not. Mammals are divided into three groups; monotremes, marsupials, and placental mammals.
What groups do humans belong to other than mammals?
These humans that you speak of belong to the placental group of mammals
Are placental mammals extinct?
No, not all mammals are placental. There are two other groups of mammals: the monotremes and the marsupials.Monotremes are egg-laying mammals, and marsupials are generally pouched mammals, although not all marsupials have fully developed pouches.
WHere do placental animals live?
All placental animals are mammals. Placental mammals are the most successful of the major mammal groups (the other two being the marsupials and the monotremes). Everything from rodents to dogs to cows and even elephants, even you, are placental mammals. In fact, they are found on every continent and in virtually every habitat on Earth.
Are chiropterans placentals marsupials or monotremes?
Marsupials, monotremes and placental mammals are all sub-groups of mammals. They share the following characteristics:vertebrateswarm-bloodedhave fur, skin or hairbreathe through lungs (not gills)the young feed on mother's milkThe major differences, however, include:monotremes are the only mammals which lay eggsmarsupial young are born undeveloped and continue most of their growth and development whilst they are in the mother's pouch, attached firmly to the teat for several months, where they receive all their nutrients.
What are the three separate groups of mammals according to reproduction?
monotreme= lay eggs marsupials= pouches placental= giving normal birth, like humans
Do humans have a placenta?
no they do not. Mammals are divided into three groups; monotremes, marsupials, and placental mammals.
What are marsupials and placental mammals?
Marsupials and placental mammals are both sub-groups of mammals. They share the following characteristics:vertebrateswarm-bloodedhave fur, skin or hairbreathe through lungs (not gills)the young feed on mother's milkThe major difference, however, is that marsupial young are born undeveloped and continue most of their growth and development whilst they are in the mother's pouch, attached firmly to the teat for several months, where they receive all their nutrients. Placental mammals, when born, are able to live independently of the mother's body.
What are some environments that placental mammals live on?
Placental mammals live in almost every environment on Earth. They are one of the most successful groups in the animal kingdom. Mammals in general are very successful and the majority of mammals are placentals. This group is so successful because they are endothermic. The only mammals that are not placentals are the marsupials (kangaroo, opossum, etc) and the prototherians (egg laying mammals). Environments that do contain mammals would likely be constrained to those that are very severe: The deep ocean, extremely high mountain peaks, etc. Otherwise you can find these animals almost anywhere.
