There are nineteen various orders of mammals. These orders are Artiodactyla, Carnivora, Cetacea, Chiroptera, Dermoptera, Edentata, Hyracoidae, Insectivora, Lagomorpha, Marsupialia, Monotremata, Perissodactyla, Pholidata, Pinnipedia, Primates, Proboscidea, Rodentia, Sirenia, and Tubulidentata.
Rodents
There are in fact THREE orders of marine mammals. These are the Cetacea, whales ,dolphins,porpoise etc. Sirenia, manatees and dugongs, and Carnivorae, walrus, seals, sea otters and polar bears.
Monotremes (Monotremes are primitive, egg-laying mammals)Marsupials (Marsupials are mammals whose babies are born very immature)Placental mammals (Placental mammals are advanced mammals whose unborn young are nourished through a placenta)
There are three orders of marine mammals; cetacea, sirenia and carnivore. The cetacea order includes whales and dolphins while the sirenia order is mostly sea cows. The carnivore order has bears, sea lions and otters.
I would say bats, there are almost 200 species.

There are hundreds of mammals, not just 5.

Yes, they do; the sub-class Eutheria (placental mammals) includes all orders of mammals except monotremes (platypuses and echidnas) and marsupials (opossums, kangaroos, etc.). Cetaceans (whales, dolphins and porpoises) are included.

Placental mammals are grouped into Xenartha (anteaters, sloths, and armadillos), Afrotheria (elephant shrews, tenrecs, golden moles, elephants, aardvarks, manatees, dugongs, and hyraxes), Euarchontoglires (rodents, rabbits, hares, pikas, tree shrews, colugos, and primates), and Laurasiatheria (hedgehogs, shrews, moles, solenodons, bats, whales, dolphins, porpoises, even-toed hoofed mammals, odd-toed hoofed mammals, pangolins, and carnivores). Each of these is further divided into orders, which are divided into families, which are divided into genera, which are divided into species. There are 21 orders and 132 families of placental mammals.
There are three main infraclass taxa into which the mammals are divided. These divisions are based on how the young are born. Of the monotremes, the marsupials and the placentals, the placental mammals far outnumber the others.If you meant orders, then Rodentia is the largest, followed by Chiroptera (bats).
