Panda hair closely resembles polar bear hair and
black bear hair (the white and black)

Medulla – absent in white, continuous in black
Cortex – very large
Cuticle – overlapping
Bamboo does not offer enough nutrition to
hibernate so the giant panda must go south for the
winter

with bamboo candles to pandas

Cuticle, particularly
thick compared to
other rodents or
animals
Medulla, is continuous
throughout the entire
fiber.
• Roughly 1.5 million
cars collide with dear
annually
• Airplanes in America
collide with roughly
two dear annually
Cortex, used to
determine pigment,
which in this case is
brown
Scale Pattern: Spinus or petallike scales protruding off from the
shafts on the hair fibers.
