KINGDOM: Animalia
PHYLUM: Chordata
CLASS: Mammalia
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
