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! :)
What else can I help you with?
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 porcupines placental?
Yes, porcupines are placental mammals. They belong to the order Rodentia and give birth to live young that develop within the mother's uterus, receiving nourishment through a placenta. This reproductive strategy is characteristic of placental mammals, distinguishing them from other groups like marsupials and monotremes.
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.
How many groups of mammals are there there are 4 groups?
There are four main groups of mammals: monotremes, marsupials, placental mammals, and the recently recognized group of egg-laying mammals. Monotremes, like the platypus, lay eggs, while marsupials, such as kangaroos, give birth to underdeveloped young that typically continue developing in a pouch. Placental mammals, which include humans and most other mammals, carry their young in the womb until they are more fully developed. Each group exhibits unique reproductive and developmental traits.
Which is the difference between the three mammal groups?
The three main groups of mammals are monotremes, marsupials, and placental mammals. Monotremes, like the platypus, lay eggs and produce milk but lack nipples. Marsupials, such as kangaroos, give birth to underdeveloped young that continue to develop in a pouch. In contrast, placental mammals, including humans, have a complex placenta that nourishes the developing fetus during a longer gestation period inside the womb.
What are the three separate groups of mammals according to reproduction?
monotreme= lay eggs marsupials= pouches placental= giving normal birth, like humans
