The Barcelona Zoo became his new home where he was adored by visitors from all over the world. During his time at the zoo, he fathered 21 children (6 lived until adulthood), and 10 grandchildren.

Answer: special vocal sacs or chambers

Interesting Information:
Before writing this quiz, I listened to their sounds, and truly it does sound like "barking,"or "whooping." Someone has rather disparagingly noted that a female's vocalization sometimes sounds like a "pig's grunt." [This "someone" was William Henry Hudson in the novel "Green Mansions."]

In their large throats, they have unique hollow, egg-shaped chambers which augment the sound. This is physiologically called an "enlarged hyoid bone."

They seem to call out the loudest either at dawn or late afternoon, and it is estimated that they can be heard for approximately three miles.

[and] understands approximately 2,000 words of spoken English" (www.koko.org). Additionally, her human IQ has been tested to be between 70 and 95.

38. In the 2008 animated movie "Space Chimps", an astrochimp named Ham III follows in the footsteps of his grandfather, Ham. The character of Ham is based on a chimpanzee in real life named Ham who, on January 31st, 1961, made history by being what?


Answer: The first hominid in space

Interesting Information:
Ham was born in July, 1956 in Cameroon. He was captured by animal trappers and sent to Florida where he was then purchased by the United States Air Force.

Specially selected out of 40 candidates, 2-year-old Ham was one of six astrochimps trained for space travel. He was named after the Holloman Aerospace Medical Centre, where he was trained. He would become the test pilot to determine if humans could survive space flight. On January 31, 1961, 44-month-old Ham was strapped onboard the capsule MR-2 and launched from Cape Canaveral on a sub-orbital flight. During the flight he successfully performed several operations, proving that it was possible to function normally under the stress of space travel.

Errors in the launching had the rocket reach a speed of 9426 km/h instead of 7081 km/h as planned. This resulted in a larger apogee (68 km higher) with Ham experiencing a longer time weightless (6.6 minutes instead of 4.7 minutes), and a greater re-entry force of 14.7g (3g higher than originally expected). Ham's flight reached 253 km above earth and lasted 16 minutes and 39 seconds. The landing of the capsule was off-target, causing a 3 hour delay in his rescue. In addition, the capsule had capsized and was leaking seawater. Ham survived with the protection of his space suit, his only injury being a bruised nose.

After the success of his mission Ham became a celebrity and appeared on television and in a movie with Evel Knievel. The sad reality, though, was his 17 years spent alone at the National Zoo in Washington, D.C. He was later moved to the North Carolina Zoo in 1980 where he had contact with other chimpanzees. He died on January 19, 1983 at the age of 26. He has no known descendants. Difficulty: Hard.

From Quiz: Chimp Off the Old Block
 
Some incorrect choices:
The first living being to go to the moon, The first chimpanzee to fly a plane, The first chimpanzee to complete the NASA astronaut training program

39. What term best defines the howler monkey's primary form of locomotion?


Answer: quadrupedal

Interesting Information:
The howler monkeys have what amounts to an additional limb in their incredibly strong prehensile tail, which may be as large as the monkey itself. Their movement is classified as quadrupedal.
Saltatory locomotion refers to leaping, hopping and jumping of certain insects. Plantigrade refers to the walking of mammals with feet on the ground.(humans, opossums and rabbits are some examples of plantigrade locomotion) Digitigrade locomotion refers to walking on the toes, such as cats, dogs and walking birds, among others.
Howler monkeys move very slowly, spending an inordinate amount of time on top of trees, munching away at and digesting leaves. Researchers estimate that they may spend as much as seventy-five percent of their time resting.
Difficulty: Hard.

From Quiz: Those Howling Monkeys
 
Some incorrect choices:
saltatory, plantigrade, digitigrade

40. Where might you go to see ringtail lemurs?
