Dall’s Sheep (North American) 1. Ruminant: Four special stomach chambers allow better digestion of tough leaves and grasses, and faster eating to avoid predators when out in the “open”; one chamber ferments food with bacteria, then the food is regurgitated for more chewing (rumination), then it’s sent through the other three chambers and on for full digestion. 2. Horns: both genders have horns, though the male’s will be bigger; used for defense from predators and by the male’s during breeding season; not shed like antlers 3. Hooves: essentially has them walking on two thickened toenails that wrap around the toe bones (like deer, giraffes, etc.); toes are flexible and able to adjust to the uneven surfaces of the steep, rocky mountain terrain. (Physical Adaptations) Snow Leopard (Snow Leopard) 1. Fur: thickness insulates in cold environment; light colored pattern camouflages with snowy, rocky slopes; large paws are covered with a cushion of hair to protect (cold & rocky surface) and give better traction in snow and ice 2. Large Lungs: larger chest capacity helps breathing in the higher altitudes of the Himalayas (less oxygen in the air) 3. Tail: Length gives balance and accuracy when leaping; thick fur gives added insulation when wrapped around the body and face at rest. Brown Bear 1. Prominent Shoulder Hump: a muscular adaptation for digging, use their paws as a powerful striking force, and attaining bursts of speed when pursuing prey 2. Claws: the long, straight claws are used for digging roots or excavating burrows of small mammals. 3. Color: While a Black Bear can actually be colored brown, the Brown Bear is not a Black Bear. The Brown Bear also has different color variation, ranging from dark brown to light blond. The “Grizzly” is actually a type of inland Brown Bear and often has lightened tips to their fur, giving them a “grizzled” effect. (Physical Adaptations) Maned Wolf (Tigers) 1. Predator features: eyes in the front, flexible spine, sharp teeth & claws, very muscular! 2. Camouflage: While its strips stand out in a zoo exhibit, they blend perfectly with the tall, shadowy grasses and plants (disruptive coloration). 3. Feet/Legs: longer back legs help with jumping, soft padding on feet quiet their approach; walking on their toes (digitigrade) gives better speed and cornering ability. (Most mammalian carnivores walk on their toes.) (Physical Adaptations) (South American) 1. Long Legs: to see better in the tall grasses 2. Excellent Senses: superb vision, exquisite sense of smell, over-sized ears help find even the smallest and most secretive prey hidden in the grasses 3. Unique: the Maned wolf is neither a wolf, nor a fox…it is the only species in its own genus. Name is from the mane-like strip of black fur on back of the head and shoulders. (Physical Adaptations) Amur (Siberian) Tiger (North American) (Physical Adaptations) Chimpanzee (Africa/Chimps) 1. Ape, not a monkey! Most monkeys have tails, apes do not; most monkeys cannot swing from branch to branch like apes can (different shoulder structure-monkeys usually run on top of branches); apes have larger brain case—very intelligent. 2. Hands: opposable thumb on hands & feet (allows for a precision grip, which is very important when using tools); Knuckle walk helps protect sensitive fingertips. 3. Omnivore: mostly eat fruit & leaves (broad incisors), but will also eat meat (sharp canines, also used for fighting) (Physical Adaptations) 2007 JBZoo Tour Cue Cards
