strockstar you are correct. My wife & I both work at a zoo...she is a primatologist who works with the Great Apes & I am a herpetologist with the reptiles & amphibians. On the chimp thing, yep, the Great Apes are the chimpanzees, gorillas, orangutans, and bonobos (a type of chimpanzee actually). The so-called Lesser Apes include Siamangs & gibbons. No apes have tails, and monkeys (which DO include baboons) have tails. So chimps are not monkeys!
One thing about the chimps is that the perception of the public is that they are cute little guys with the white faces sranding about a foot & a half tall. Those chimps you see in Tarzan movies & other media are usually about a year & a half old. They QUICKLY outgrow this cute stage & a full grown male chimp is a huge, strong animal, standing nearly 6 feet tall & weighing several hundred pounds, with fingers as big around as a banana. I remember when I first began working at the zoo 13 years ago & saw my first adult chimp..I actually thought it was a gorilla (and when I actually got close to my first gorilla....wow).
Also, chimps are extremely aggressive & carnivorous....a pack of chimps will attack & kill monkeys & other mammals, and even other chimp troups in a bloody, nasty "war" (gorillas are vegetarians incidently & quite a bit less aggressive than chimps). So having a chimp for a pet is downright foolhardy & just asking for trouble (my wife is actually missing the tip of her middle fingers courtesy of getting too familiar with a chimp while feeding it grapes during her "I'm just getting started working in a zoo" period!

Naturally, the news of what happened to this lady was all over the zoo community & was a complete tragedy all around, for the chimp as well as the victim. We tell people constantly how poor "pets" chimps & monkeys (which can ALSO tear you up if they are in the mood to, even the smaller species) are & to avoid the urge to get one at ALL costs!!!!!

BTW...as for MY area of expertise, crocs & alligators are basically distinguished in the ways mentioned by strockstar...the 4th tooth in the lower jaw of a croc juts up over the upper jaw, Wolfman-style. In alligators, this tooth fits into a socket in the upper jaw. Alligators therefore have a wider head & crocodiles a narrow head & snout. Crocs also grow to much greater size than alligators are are much more heavily muscled & aggressive.
