Bite contains anticoagulant to prevent clotting
What is myrmecophagy?
Consumption of termites or ants
How is a koala adapted to its diet?
Grinding molars, powerful jaw, enlarged caecum, small stomach, detoxifying bacteria
What is special about the kidney of vampire bats?
Can tolerate osmotic stress from feeding on blood
How do dogs pursuit their prey?
Social flexibility, opportunists
What is the teeth of a mammal which eats ants teeth like?
Peglike, reduced teeth
What is coprophagy?
Eating faeces or dung
What is an advantage of a herbivorous diet?
Dont have to pursuit prey, plentiful
How do fishing bats find fish?
Echolocation off surface
What is unqiue about aquatic herbivores molars?
Continuous replacement
What is the adaptation of the pseudo thumb?
Allows the pando to grip bamboo stems
What is bad about being a folivore?
Low nutrient content
What is the pandas thumb?
Modified wrist bone
What other specialisations do ant eating mammals have?
Extended tongue and snout, digging limbs
What the carnassial shear
Cheek teeth which allow carnivores to tear meat apart
What is the caecum?
Pouch connected to the junction of the small and large intestine
What sensory adaptations do star nosed moles have for fossorial feeding?
Eimer’s organ
How do cats pursuit their prey?
Retractile laws, large ears, tongue covered in papillae
What is a herbivores skull and dentition specialised for?
Grazing, browsing and gnawing
What is an omnivores dentition like
Versatile. Piercing front teeth, flattened cheek teeth
What is a herbivores dentition like?
Reduced canines, diastema from no incisors, grinding molars
Why is surplus killing useful?
Save food until it is less abundant
What is an insectivore stomach like?
Short intestine, no cecum
What is stereoscopic vision?
Perception of depth and 3D structure from visual information
What is food cacheing?
Sotage of food in locations hidden from the sigh of both conspecifics
What is the main focus of fermentation in the foregut?
Slow passage time
How do frog eating bats use echolocation?
Texture of frog’s skin to distinguish between toxic/non-toxic species
What is a disadvantage of a herbivorous diet?
Low energy. Need to take large volumes
What is unique about rodent incisors?
Continual growth
How are sloths adapted to their diet?
Stomachs with multiple compartments with symbiotic bacteria to break down leaves
What is the function of the 3rd finger in primates?
Tap trees to hear invertebrates and to probe out of crevices
What is unique about a bats diet?
Generalist and opportunistic feeders
What is the function of coprophagy?
Re-absorption of nutrients as it moves too quickly through the digestive system
What is a nonrumiant herbivore stomach like?
Simple stomach and large cecum
What is surplus killing?
Killing more prey than they can immediately eat
How do Eimer’s organs help to forage?
Detect structures and shapes. Fluid in each sinus transmits information to sensory neurons
What is scatter cacheing?
One food stored at each cache site
What is the Ailurid radial sesamoid?
Panda pseudo thumb
What is a carnivore dentition like?
Large canines, pronounced carnassials
How are bats specialised for nectivory?
Elongated snouts, reduced teeth, protrusible tongue
What is viscous saliva?
Thick, sticky consistancy for the break down of chitin
