mammals Flashcards
Mammary Glands
the milk-producing gland of women or other female mammals.
Hair
way to stay warm
Endothermic
accompanied by or requiring the absorption of heat.
Insectivores
is a carnivorous plant or animal that eats insects. An alternative term is entomophage, which also refers to the human practice of eating insects. The first insectivorous vertebrates were amphibians.
Carnivores
an animal that feeds on flesh.
Omnivores
an animal or person that eats food of both plant and animal origin.
Ruminant herbivores
, such as rhinoceroses, horses, and rabbits, are not ruminants, as they have a simple single-chambered stomach. These hindgut fermenters digest cellulose in an enlarged cecum through the reingestion of the cecotrope.e
Incisors
a narrow-edged tooth at the front of the mouth, adapted for cutting. In humans there are four incisors in each jaw.
Molars
grinding tooth at the back of a mammal’s mouth.
Canines
the sharp tooth
Monotremes
Monotremes are mammals that lay eggs instead of giving birth to live young like marsupials and placental mammals.
Marsupials
Marsupials are an infraclass of mammals living primarily in Australasia and the Americas.
Placental
Placentalia is one of the three subdivisions of the class of animals Mammalia; the other two are Monotremata and Marsupialia.
Chiroptera
Bats are mammals of the order Chiroptera whose forelimbs form webbed wings, making them the only mammals naturally capable of true and sustained fligh
Primates
A primate is a mammal of the order Primates. In taxonomy, primates include two distinct lineages, strepsirrhines and haplorhines
Xenarthra
The superorder Xenarthra is a group of placental mammals, extant today only in the Americas and represented by anteaters, tree sloths, and armadillos.
Rodentia
Rodents are mammals of the order Rodentia, which are characterized by a single pair of unremittingly growing incisors in each of the upper and lower jaws.
Lagomorpha
The lagomorphs are the members of the taxonomic order Lagomorpha, of which there are two living families: the Leporidae and the Ochotonidae.
Proboscidea
The Proboscidea are a taxonomic order of afrotherian mammals containing one living family,
Sirenia
Manatees are large, fully aquatic, mostly herbivorous marine mammals sometimes known as sea cows.
Perissodactyla
Perissodactyls, otherwise known as odd-toed ungulates, compose an order of mammals characterized by an odd number of toes and being hindgut fermenters with somewhat simple stomachs.
Artiodactyla
The even-toed ungulates are ungulates, hoofed animals, whose weight is borne approximately equally by the third and fourth toes
Cetacea
Cetacea, are a widely distributed and diverse infraorder of carnivorous, aquatic, mammals, unable to survive on land.
Therapsids
Therapsida is a group of synapsids that includes mammals and their ancestors.
