KINGDOM: AnimaliaPHYLUM: ChordataCLASS: Mammalia Life Processes - Bat
Movement • Flight • Only mammal that can achieve sustained flight • Wings – webbed forelimbs; membrane is VERY elastic • Digits – bones periodically spaced out among the wing flap; fan-shaped; very flexible due to low calcium levels
Body Covering • Fur • Membrane between digits - flexible
Support • Skeleton: fingers, humerous, radius, ulna, skull, spine, thumb, elbow joint • Digit bones are very flexible due to lack of calcium
Nutrition • Bugs - consumes 1/3 of it’s body weight in bugs each day. • Fruit • Water – drink by skimming across surface water and then licking fur • Two sharp teeth to puncture through hard shell of insect
Respiration • Breath air
Circulation • Standard circulatory system; warm-blooded • Heart is extremely large compared to size of body; beats 1400 beats per minute down to 20 beats per minute depending on species • Because Bats hang upside down they have one-way valves in their arteries as well as their veins to help pump the blood through their body. • Valves will close to retain blood in body during inactivity to retain body heat or radiate heat from the body while extremely active such as flying
Excretion • Guano - Bat feces so rich in nutrients that they mine it an use it as fertilizer.
Responses • Echolocation – Bats use sonography to create a mental picture of what is in front of them. • Eyes – bats can see quite well • Hibernation during cold months • Touch receptors to help fine tune flying and catching insects
Reproduction • Live birth • Feed their young through mammary glands
