Why learn about hair and teeth?

They reflect the ecology and evolution of mammalian taxa

What are the two types of hair growth?

• Definitive

• Angora

shed and replaced once given length reached

Definitive

grows continuosuly

Angora

the total body covering of hair

pelage

Types of pelage

• Vibrissae

• Gaurd hair

• Underfur

• long, stiff hairs that serve as tactile receptors

• high blood supply

• ex) whiskers

Vibrissae

Two types of Guard hairs

• Awn

• Bristles

• most common

• outer layer of hair on most mammals

• definitive growth, expanded distally, weakened basally

Awn

Bristles
