Class mammalia
Class Mammalia

  • Subclass Prototheria- extinct mammals with unique skull structure

  • Subclass Theria- Living mammals distinguished by skull

    • Infraclass Ornithodelphia- Monotremes

    • Infraclass Metatheria- Marsupials

    • Infraclass Eutheria- Placentals


Order monotremata
Order Monotremata

  • Oviparous or egg laying mammals

  • Only 3 in existence

  • Duck-billed platypus and two species of spiny anteaters called echidna.

  • Not completely endothermic (their body temperature is lower and fluctuates more than other mammals)

  • Mammae without nipples

  • Edentulous as adults

  • Limbs modified for

    swimming or digging

  • Australia and New Guinea


Duck billed platypus ornithorhynchus anatinus
Duck-Billed PlatypusOrnithorhynchus anatinus

  • Only member of the mammal family Ornithorhynchidae

  • Greek platys meaning broad and pous meaning foot

  • Several reptilian characteristics: same opening for reproduction and eliminating waste products, the ability to lay eggs

  • The world's only venomous furred animal

    • Spur on hind foot

    • Females loose after one year

  • Bill contains an electro-receptor system


Echidna spiny anteater tachyglossus aculeatus
Echidna (Spiny Anteater)Tachyglossus aculeatus

  • "Echidna" derives from the Latin word for "viper”

    • Tongue protrudes like a snake

  • Nocturnal

  • Terrestrial and burrowing

  • Females normally lay only one egg

Infraclass metatheria marsupials
Infraclass Metatheria(Marsupials)

  • Old classification placed all marsupials in a single order

  • More recent classifications have recognized the diversity and radiation of Marsupials

  • Marsupials now separated into seven orders

  • Range, North America, Central America, South America, Australia, New Guinea, adjacent islands

Marsupials
Marsupials Guinea, Tasmania, And the Americas

  • Give birth to tiny immature young that crawl to a pouch on the mothers belly immediately after they are born.

    • Marsupium- Fold of skin protecting nipples


They attach themselves to milk secreting nipples nursing until they are mature enough to survive outside the pouch.

Placental mammal s
Placental Mammal until they are mature enough to survive outside the pouch.s


Characteristics of placentals
Characteristics of Placentals until they are mature enough to survive outside the pouch.

  • 95% of all mammals

  • Carry unborn young in the uterus until young can survive in the wild.

  • Oxygen and nutrients are transferred from mother’s blood to baby’s blood


Placental characteristics
Placental Characteristics until they are mature enough to survive outside the pouch.

  • The placenta is a membrane providing nutrients and waste & gas exchange between the mother and developing young

  • Gestation period-is the time which mammals develop in mother’s uterus

Order insectivora
Order Insectivora Some mammals can fly!

  • Consists of 400 species

  • Includes shrews and moles

Shrew

Mole


Order insectivora1
Order Insectivora Some mammals can fly!

  • Small animals with high metabolic rate and found in North America, Europe, and Asia.

  • Most have long pointed noses that enable them to grub for insects, worms, and invertebrates.

  • Live on ground, trees, in water, and underground.


Order rodentia
Order Rodentia Some mammals can fly!

  • Largest mammalian order having over 2,400 species.

  • On every continent except for Antarctica

  • Includes squirrels, marmots, chipmunks, gophers, muskrats, mice, rats, and porcupines.

Order lagomorpha
Order Lagomorpha and used for gnawing

  • Includes rabbits, hares, and small mountain mammals called pikas.

  • Found worldwide

  • Warrens- families of rabbits

Hare

Pika


Rabbits vs hares
Rabbits vs. Hares and used for gnawing

  • Rabbits are smaller and slower

  • Shorter ears and hind legs with smaller feet

  • Solid colored fur

  • A young rabbit is a bunny

  • Altricial

  • Hares are generally larger and faster

  • Hares have longer ears, longer hind legs, and larger feet

  • Hares have black markings on their fur

  • A young hare is called a leveret

  • Precocial


Order lagomorpha1
Order Lagomorpha and used for gnawing

Double row of incisors, large front teeth backed with two smaller ones, adaptation for herbivorous diet.


Order edentata xenarthra
Order Edentata/Xenarthra and used for gnawing

  • Made up of 30 living species including anteaters, armadillos, and sloths.

  • The name edentate means “without teeth”

  • Those with teeth have single root with teeth and no enamel

  • Live throughout the world except in polar environments



Order chiroptera
Order Chiroptera between extremely long finger bones

Order carnivora
Order Carnivora dugongs

  • 250 living species in carnivoria are distributed worldwide

Orders artiodactyla and perissodactyla
Orders Artiodactyla and Perissodactyla plant material as well as meat, so they are called omnivores.

  • Ungulates-hoofed mammals

  • These two classes are herbivores.

    • Mostly grazers/browsers

  • Ruminants- four chambered stomach

  • The first three chambers are for storage (rumen), use cellulase (digestive enzyme) to aid in breakdown of cellulose

    • “Chewing the cud”

      • Regurgitate, chew again, and undergoes double digestion.


Order artiodactyla
Order Artiodactyla plant material as well as meat, so they are called omnivores.

  • Ungulates with an even amount of toes

  • Pigs, hippos, camels, antelope, deer, sheep, giraffes, cattle


Order perissodactyla
Order Perissodactyla plant material as well as meat, so they are called omnivores.

- Ungulates with an odd number of toes

- Horses, rhins, zebras, and tapirs


Order proboscidea
Order Proboscidea plant material as well as meat, so they are called omnivores.

  • Characterized by a boneless nose or proboscis

  • Elephants are the largest land dwellers alive today, weighing more than 6 tons.

    • African (largest land mammal) and Indian/Asian species



Order primates
Order Primates and stripping bark from branches.

  • 200 living species of primates classified as prosimians.

  • Including lemurs, tarsiers, monkeys, gibbons, and great apes


  • Omnivorous diets and stripping bark from branches.

  • Unspecialized teeth

  • Grasping digits with free-moving limbs

  • Finger and toenails
