Discuss the features and history |
Tarsidae -large eyes -primarily leapers with modified ankle bones-Oriental distribution -(Eocene Prosimians) 5-7 spp. -Insectivores or Exudativores -Very large eyes (larger than their brain -Small -Nocturnal -Leapers -Name comes from the elongation of the two tarsal bones so they now behave like radius and ulna and maintain ability to grasp with foot |
|
|
List 6 morphological adaptations shared by many arboreal animals: |
1. Relatively reduced and evenly distributed weight 2. Equal size of distal and proximal limb elements 3. Highly flexible, mobile limbs (especially shoulder and elbow) 4. Grasping hands/feet with opposable digits 5. Prehensile tail (5th limb) 6. Well-developed binocular vision |

What is “brachiating”? |
Arboreal locomotion |
|
|
Give information about the “hands” and feet of arboreal animals. |
Give information about the “hands” and feet of arboreal animals. |

Discuss Order Primates |
-Arboreal adaptations -Hallux and Pollex (thumb and large toe) usually opposable -Typically nails vs claws -Relatively larger brain size -Vision well-developed -olfaction reduced |
|
|
Lemuriformes |
-Digits have nails, except for a claw on digit 2 of foot -Lower incisors procumbent and form a comb with the canines (also used to get exudate from trees) -Good example of adaptive radiation on Madagascar(the other good example is Tenrecs) -Upper incisors small with a medial gap |
|
Suborder: Lemuroids: Family Lemuridae (Lemurs) |
-Elongated rostrum -Mostly leapers -Endemic to Madagascar -Ethiopian distribution -Large social groups -Scent glands in wrists -Semi-arboreal |
|

|
What is this? |
Lemur catta Ring-tailed Lemur Notice the lower incisors, and elongated rostrum |

Discuss: Suborder: Lemuriformes: Family: Indriidae |
-Indris, Sifakas-Leapers both on land and in trees |
|
Suborder: LemuriformesFamily Cheirogaleidae |
-Dwarf Lemurs and Mouse Lemurs -Incrassated tails -Mostly arboreal quadrupeds -Endemic to Madagascar -Some of the smallest primates -Estivate (similar to hibernation, but during the summer) |
|
|
Suborder: LemuriformesFamily CheirogaleidaeCheirogaleus medius (dwarf lemur) |
|
Suborder: Lemuriformes Family Daubentoniidae |
-Aye-Aye-Elongated fingers (3rd bears a long claw) for probing tree holes -Fills the woodpecker niche in Madagascar -One pair of upper and lower incisors (similar to wombats) |
|
What is this? |
Suborder: Lemuriformes Family Daubentoniidae Aye-Aye Very enlared 3rd digit |
|
|
Suborder: Lorisoids Family Lorisidae Lorises and Pottos Lorises are Oriental Pottos are Ethiopian Arboreal quadrupeds Adaptations in hands to prevent constriction to allow for grasping for long periods of time Venomous glands in the elbows of one species (toxin abates over time if they are not fed their natural diet) Dense, woolly fur Hindlimb and forelimbs generally the same length Hands and feet strengthened for gripping substrate |
