Wildlife Damages Animals may not avoid oil spills Oil coats animal’s bodies Oil that sticks to feathers and fur

causes: Hypothermia Decreased Buoyancy Increased predation Malnutrition Damage scent Internal health problems

Page 10: Oil spills  darian scorgie

Hypothermia Destroys insulation and waterproof

features Lanugo – wooly fur insulation

Buoyancy Oiled feathers at weight

Drowning of birds Fur seal pups

Unable to stay afloat with oiled fins

Matted feathers Oiled flippers

Causes low body temperature Metabolism tries to combat cold, body

weight diminishes Prey contamination
