Type of animal science: Classification Fields of study: Anatomy, conservation biology, developmental biology, ethology, physiology,
reproduction science Camels, the one-humped dromedary and the two-humped Bactrian, are well-adapted to the desert regions of Africa,
the Middle East and Central Asia, where they are used for transport, milk, and meat. They can live without water
longer than other large mammals.
Type of animal science: Anatomy, behavior, ecology, evolution Fields of study: Anatomy, conservation biology, ecology, ethology, paleontology, wildlife ecology,
zoology Carnivores (literally, “flesh eaters”) are one of the most successful orders of mammals. Most species are endangered
by human persecution and habitat destruction.
Type of animal science:Classification Fields of study: Anatomy, paleontology, physiology, wildlife ecology The cat family contains some thirty-six extant species, usually grouped into four genera. They are native to every
continent except Australia and Antarctica.

ecology Cattle and buffalo are the major domesticated oxenlike animals in the world, while bison have never been domesticated,
became nearly extinct, and have made a comeback in North America.
Type of animal science:Anatomy, classification, reproduction Fields of study: Anatomy, invertebrate biology, zoology Over twelve thousand species of the arthropods centipedes and millipedes are known. Centipedes are carnivorous,
and millipedes are usually vegetarians.
Type of animal science: Anatomy, classification, reproduction Fields of study: Anatomy, zoology Chameleons, the family Chamaeleontidae, have long, sticky tongues to capture prey. Other unique characteristics include
eyes that operate independently of each other, leaflike body shapes, ability to change skin color, zygodactyly, and
prehensile tails.
Type of animal science: Classification Fields of study: Anatomy, behavior, physiology, reproduction The fastest land mammals, cheetahs originated millions of years ago, before any of the other big cats, but are now an
endangered species.
Type of animal science: Anatomy, behavior, classification Fields of study: Anthropology, ethology, zoology Two species of chimpanzees exist and are classified under the order Primates, an order of extreme physical variability
and complexity. Chimpanzees are humans’ closest relatives and exhibit significant learned behaviors.
Type of animal science:Anatomy, classification, ecology Fields of study:Anatomy, ecology, marine biology, zoology The category of clam is confusing, because there are some organisms found in freshwater or marine environments that
are termed clams and some that are termed mussels. In sea water, fourteen marine organisms called clams are commercially
valuable. Chief among these are the Atlantic surf clam and the ocean quahog. Scientists recognize twelve
living genera of oysters but, as more studies are made by classification experts, the actual number may be slightly
more or slightly fewer. In the United States, four species are commercially important, with the eastern oyster,
Crassostrea virginica, leading the list.
Type of animal science:Classification Fields of study: Entomology There are more than 3,700 species of cockroaches, also called roaches. They are among the oldest insects, having a fossil
record that dates back about 340 million years.
Type of animal science:Anatomy, classification Fields of study: Anatomy, invertebrate biology, marine biology Coral refers to a large group of marine invertebrates, class Anthozoa, in the phylum Coelenterata. Anthozoa form
reefs, gorgeous coral bushes, and precious coral.
Type of animal science: Classification Fields of study: Anatomy, zoology Coyotes are carnivorous mammals which belong to the Canidae family and share similar anatomical, behavioral traits with wolves and dogs.
Type of animal science:Anatomy, classification Fields of study: Anatomy, invertebrate biology, marine biology Crabs are joint-legged crustaceans of the phylum Arthropoda. Phylum characteristics include a
chitinous exoskeleton, jointed appendages, a ventral nervous system, and a dorsal brain.
Type of animal science: Classification Fields of study: Anatomy, conservation biology, physiology, population biology, wildlife ecology Cranes are among the oldest of living bird groups, dating back sixty million years. Their interesting appearance, majestic
flight, and unusual behavior characteristics have made them the subject of reverence and folklore around the
world.
Type of animal science: Anatomy, classification, ecology, reproduction Fields of study: Anatomy, ecology, invertebrate biology, marine biology, zoology The twenty-five thousand species of crustaceans make up the class Crustacea. They are mainly aquatic arthropod
animals which have jaws and two pairs of antennae. Examples are crabs, lobsters, and shrimp. Crustaceans are food
for humans and whales and have useful ecological functions.
Type of animal science: Anatomy, behavior, classification, ecology, evolution, geography, physiology,
reproduction Fields of study: Anatomy, conservation biology, ecology, herpetology, paleontology, physiology,
reproduction science, systematics (taxonomy), zoology The Crocodilia, comprising twenty-three endangered species, are the last surviving reptilian group of the subclass
Archosauria, which also includes the extinct dinosaurs, pterosaurs, and the stem group Thecodontia. Crocodilians
are the closest living relatives of birds, and most species are highly endangered due to hunting and habitat destruction.
