Eagles

Eagles

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.

Echinoderms

Echinoderms

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.

Eel

Eel

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.

Elephant seal

Elephant seal

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.

Elephant

Elephant

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.

Elk

Elk

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.
