Aguoti
Mixture or bands of two pigments
Canines
Most forward tooth in maxillary
Epidermal bone
Reptiles have this in scales Armadillo scales Pangolin
Selenodont
Single cusp fuses into crescent shape Most herbivores
Mammary glands
Characteristic of mammals Specialized epidermal glands that grow deep in hypodermis, forming ducts surrounded by milk producing cells
Incisors
Chisel like
Sebacious glands
Derived from epidermis Associated with hair folicles
Bunodont molars
Teeth possessing four major cusps arranged in a rectangle -Seen in humans, primates, pigs and omnivores
Dermal bone

Structure of integument
epidermis, dermis, hypodermis
Prolactin

Hooves
the tips of the toes of animals like horses
Role of integument
-seperate internal from external -disease barrier -insulation -water conservation -communication
Cryptic coloring
Match surroundings ex: deer fawn

opposm

Hypodermis
Layer of connective tissue and fat below the dermis
Premolars
Up to 4, have fewer cusps
Dilambdodont
W-shaped
Intraspecific variation
among members of the same species due to habitat variation
Melanism
an increased amount of black or nearly black pigmentation (as of skin, feathers, or hair) of an organism, resulting from the presence of melanin.
Angora
grows continously
Zalambdodont
having molar teeth with V-shaped ridges
Homodont
having teeth that are uniform in form, shape, and function.
Brachyodont
