Type of animal science: Anatomy, classification Fields of study: Anatomy, conservation biology, herpetology, systematics (taxonomy) Nearly four hundred species of salamanders and newts are classified in the order Caudata. The two areas of greatest
diversity of species in the world are in the southeastern United States and in Mexico and Central America.
Type of animal science: Classification Fields of study: Anatomy, ecology, marine biology, reproduction science Salmon and trout are salmonid food and game fishes of the Northern Hemisphere.
Type of animal science: Classification, evolution Fields of study: Anatomy, evolutionary science, paleontology, systematics (taxonomy) Sauropods are a group of dinosaurs that include the largest land animals that ever existed. Together with the
theropods, or carnivorous dinosaurs, they form a group known as the Saurischia.
Type of animal science: Anatomy, classification, ecology Fields of study: Anatomy, ecology, invertebrate biology, systematics (taxonomy), zoology Scorpions are one of the most ancient land animals, having evolved over 400 million years ago. There are over 1,300
species of scorpions occurring over every continent except Antarctica. Scorpions are known for their stinging apparatus,
but relatively few species pose any danger to humans.
Type of animal science: Classification, reproduction Fields of study: Anatomy, conservation biology, ethology, marine biology, physiology, reproduction
science, wildlife ecology At least thirty-five species of seahorses, classified in the genus of Hippocampus, live in shallow subtropical coastal
areas around the world. They swim in an upright position and have a head suggestive of a horse, a prickly looking
body, and a prehensile tail. The male incubates eggs in a pouch in its abdomen and gives birth to live young.
Type of animal science: Classification Fields of study: Anatomy, ethology, genetics, marine biology, physiology Essentially aquatic, warm-blooded mammals, seals and walruses are widely distributed throughout the world, although
most of them gravitate to the colder areas.
Type of animal science: Classification Fields of study: Anatomy, systematics (taxonomy), zoology Cartilaginous fishes constitute one of the seven living classes of vertebrates. There are about seven hundred living
species of sharks, rays, skates, and ratfishes in this vertebrate group that has ancient origins.
Type of animal science: Classification Fields of study: Anatomy, zoology Over nine hundred breeds of sheep have been identified worldwide, and four hundred have significant research data
available to allow for distinctive, productive evaluation.
Type of animal science: Anatomy, behavior, classification, reproduction Fields of study: Anatomy, classification, zoology Small, ferocious shrews sometimes have venomous saliva. They are ecologically useful because they eat carrion and
harmful insects.
Type of animal science: Anatomy, classification, reproduction Fields of study: Anatomy, zoology Skunks, related to weasels, are known for the vile odor of their musk. They are helpful to farmers, eating animals that
prey on agricultural products. Their fur is used for garments and some people keep them as pets.
Type of animal science: Anatomy, classification, reproduction Fields of study: Anatomy, invertebrate biology, zoology Snails are marine, freshwater, and land mollusks belonging to the class Gastropoda. Some are used for food; others are
ecologically useful.
Type of animal science: Classification, evolution Fields of study: Evolutionary science, herpetology, systematics (taxonomy) Snakes are squamate reptiles with slender, elongate bodies that lack limbs. In spite (or because) of these features,
snakes have successfully exploited many habitats and lifestyles.
Type of animal science: Classification Fields of study: Anatomy, ornithology, systematics (taxonomy) Sparrows are some of the most widespread and successful of all songbirds.
Type of animal science: Classification, ecology, evolution, geography Fields of study: Ecology, evolutionary science, systematics (taxonomy) Spiders are members of phylum Arthropoda, the dominant animals on earth in terms of both number of species and
number of individuals. Of an estimated ten million species of arthropods, only 10 percent have been identified.Aclose
examination of spiders helps to understand other arthropods.
Type of animal science: Classification, ecology, reproduction Fields of study: Anatomy, zoology Thousands of sponge species occur, most in the oceans. They are sexual hermaphrodites, and also reproduce asexually.
Sponges are useful commercially.
Type of animal science: Classification, ecology, zoology Fields of study:Ecology, systematics (taxonomy), wildlife ecology, zoology Squirrels are mammals belonging to the family Sciuridae. Consisting of 272 species, this family represents only about
5 percent of mammal species. Nevertheless, squirrels are very familiar mammals to most people.
Type of animal science: Classification Fields of study:Anatomy, invertebrate biology, zoology Starfish are five orders (1,500 species) of marine invertebrate animals making up the echinoderm class Asteroidea.
Their main foods include mollusks and coral.
Type of animal science: Classification, evolution Fields of study:Anatomy, evolutionary science, paleontology, systematics (taxonomy) Stegosaurs were a group of armored, herbivorous dinosaurs characterized by large plates set vertically along the back
and spikes on the tail. The plates are thought to have acted as thermoregulatory devices.
Type of animal science: Classification Fields of study:Anatomy, conservation biology, physiology, population biology, wildlife ecology Storks are wetland birds that are physically striking in appearance and noted for their spectacular flight. They are
found throughout the world, but their numbers have decreased dramatically due to habitat destruction by humans.
Type of animal science:Anatomy, classification, reproduction Fields of study:Anatomy, ornithology, zoology Swans are the largest, most beautiful waterfowl. Some species were hunted almost to extinction for their feathers, before
legislation protected them.
