Type of animal science: Classification Fields of study: Anatomy, ornithology The eagles of the world are swift, powerful birds of prey long admired for their power, ferocity, and regal bearing. All
are characterized by a large, hooked bill, keen vision (called “eagle-eyed sight”), and long, broad wings for lifting prey.
Type of animal science: Classification Fields of study: Anatomy, invertebrate biology, physiology Echinoderms are radially symmetrical, free-moving marine organisms, such as starfishes, sea urchins, brittle stars,
sea cucumbers, and sea lilies.
Type of animal science: Classification Fields of study: Anatomy, ethology, marine biology, physiology, zoology Eels are a variety of fishes possessing an elongate, snakelike body form. Eels inhabit both freshwater and marine environments,
and some eel species move back and forth between the two environments at different stages of their life cycles.
Although eels are not the most charismatic of aquatic organisms, their life histories make them some of the most
fascinating and poorly understood marine animals.
Type of animal science: Classification Fields of study: Anatomy, conservation biology, ecology, marine biology, physiology, zoology Elephant seals are carnivorous marine mammals that spend time on land and in the ocean. There are two distinct species:
the northern and the southern elephant seal. Both species have claws on their front flippers and both lack external
ears. A trunklike nose anatomically differentiates the males. Blubber provides buoyancy and insulation. Elephant
seals swim using their rear flippers.
Type of animal science: Classification Fields of study: Anatomy, behavior, ecology, physiology Found in parts of Africa and Asia, the elephant is the largest land animal, anatomically differentiated by tusks, a
trunk, and a massive head. Elephants are herbivores, with distinct behavioral and physical characteristics.
Type of animal science: Behavior, classification, ecology Fields of study: Ecology, wildlife ecology, zoology Elk, also known as wapiti, are members of the mammal order Artiodactyla. They are noted for their large antlers.
