Type of animal science: Anatomy, ecology Fields of study: Ecology, marine biology The great depths of the sea, below about 150 feet, had always been considered azoic (without animal life). Oceanographic
research has shown the ocean supports a large number and diversity of animals in all areas, from the surface to
the bottom of the deepest parts, nearly six miles down.
Type of animal science: Classification, evolution Fields of study:Anatomy, archaeology, evolutionary science, paleontology, physiology, zoology Dinosaurs were one of the most successful early life-forms, thriving for more than 150 million years before becoming
extinct by the end of the Cretaceous period. The reasons behind their longevity and their sudden extinction hold important
implications for humankind’s own survival.
Type of animal science: Classification Fields of study: Anatomy, zoology Dogs are carnivorous mammals which belong to the Canidae family and share similar anatomical
and behavioral traits with wolves and coyotes.
Type of animal science: Classification Fields of study: Anatomy, marine biology, physiology, zoology Toothed whales are cetaceans, suborder Odontoceti. They use teeth to capture cuttlefish, squid, and other prey. Some
are endangered species perceived to be quite intelligent.
Type of animal science: Classification Fields of study: Anatomy, ornithology Ducks are among the most common and widespread of aquatic birds. Like other members of the Anatidae family, they
have webbed feet, a boat-shaped body, a dense covering of feathers, and a broad and somewhat flattened bill.
