- 2. Presented by>>>>Saif ullah buneri Wagma sundri Benish Presented to >>>My dear Sir Zaheer Ahmad Khan
- 3. Pilosa in Latin means hairy Contains anteaters and sloths Found only in the Americas today Central and South America Origins are unclear but can be traced back to South America in the early Tertiary Pilosa Facts
- 4. Scientific classification Kingdom: Animalia Phylum: Chordata Class: Mammalia Superorder: Xenarthra Order: Pilosa Suborder: Vermilingua Family: Myrmecophagidae Genus: Myrmecophaga Species: M. tridactyla Binomial name Myrmecophaga tridactyla
- 5. / • Cyclopediae • Silky Anteater • Myrmecophagidae • Giant Anteater • Northern Tamandua • Southern Tamandua
- 6. Specialized to eat ants and termites Jaws Became longer snouts Teeth have been reduced Tongues have became longer Spine covered Very strong forelimbs and claws For digging up termite nest and ant hills Opening up tree bark Can be used in defense against jaguars (Giant anteater) Walk on knuckles with claws curved under
- 7. • Suborder Folivora • Bradypodidae • Pygmy Three-toed sloth • Brown-throated Three-toed sloth • Pale-throated Three-toed sloth • Maned Three-toed sloth
- 8. Megalonychidae • Hoffman’s Two-toed sloth • Southern Two-toed sloth
- 9. Megatheriidae megatheriid ground sloths Mylodontidae Myylodontid ground sloths Orophodontidae orophodontid ground sloths Scelidotheriidae Scelidotheriid ground sloths
- 10. Long curved claws used to hang from branches Slow moving Specialized in eating leaves Canine teeth have receded Now have ever growing peg-like molars Tree dwelling Hang upside down Can swim and move about on the ground. Fur on their stomach curves to the back .
- 11. Background Have a resting metabolic rate less than half that of a typical placental mammal Move slowly Muscles and nerves function more slowly than typical mammals The effect of these traits influence there net energetic cost and attendant food requirements
- 12. Results Water influx and efflux where nearly equal Metabolic rates where highest in males and least in no reproductive females but the difference was not significant Diet provides 10.4 metabolizable kJ food.
- 13. Findings Energy Metabolism Aspects that contribute to low energy requirements Low and variable body temperature Behavioral thermoregulation Large portion of body mass as metabolically inactive material Heat-conserving rate in blood vessels in limbs Slow acting muscle and nerve fibers Water fluxes Approximate water balance Gets all of it’s water requirement from young and old leaves Energy assimilation Assimilation efficiency depends on the mix of leaves in the gut
- 14. Adaptations for specific foods Anteaters Forelimbs and Claws Snout and Tongue Sloth Live in trees Move slow Have a common ancestor to armadillos Sloth Digestion and metabolism Traits that require low energy requirments Slow metabolism
