Adaptations How Animals Survive
What is Adaptation? • All animals live in habitats. • Habitats provide food, water, and shelter which animals need to survive. • Animals also depend on their physical features to help them obtain food, keep safe, build homes, withstand weather, and attract mates. • These physical features are called physical adaptations.
Squirrel Monkey • Located in South America • Diet consists of insects, spiders, bird eggs, fruit, and nuts. • Squirrel monkeys move through the trees by leaping. They have thighs that are shorter relative to their lower legs; this allows more jumping force.
Squirrel Monkey • They distribute a musky glandular secretion throughout their fur (especially on tail) as scent to mark territory or to leave a trail for others of the troop to follow as they go through the trees. • This odor turns away hunters who might otherwise kill them for food.
Polar Bears • Located in the Arctic • Diet consists of seal and fish. • They have longer legs than other bears and large furry feet that help to distribute their weight as they walk on thin ice. • Their fur is made of hollow hairs which trap air and help to insulate them in the frigid waters.
Giraffe • Located in sub-Saharan Africa, north-eastern Kenya, eastern Sudan and Eritrea. • giraffe also eat flowers, vines and herbs, and may chew on bones, perhaps to gain additional minerals. • An average of 16-20 hours per day are spent feeding and up to 140 lbs of fresh browse are taken.
Giraffe Thorns are not a deterrent to feeding; the long, prehensile, muscular tongue (which can be extended up to 18 inches), thick, gluey saliva, and special upper palate shape enable the giraffe to process thorny foods.
