Caribou are large-scale migratory animals and have been known to travel up to a day. The migratory activities of caribou are usually driven by weather conditions and food availability. Changes in caribou migration can be problematic for Alaska Natives, who depend on caribou for food.

Leatherback sea turtle
Leatherback sea turtles often inhabit open waters but are still sometimes seen on coastal waters because of their title of the most migratory sea turtle species. It is the largest turtle in the world, weighing up to two thousand pounds and reaching up to six and a half feet by their adult years. The shell of the leatherback turtle, also called a carapace, can develop to one and a half inches and is the only shell on a sea turtle that is not hard and boney but rather soft and leather like to the touch. The front flippers on the leatherback turtle are not equipped with scales and claws unlike other species, and they outgrow the flippers on other species of sea turtles.
Green sea turtle
The green sea turtle is named after its distinct green skin color, contrary to the idea that the green comes from their shell, which is typically brown or a dark olive. This turtle is capable of gaining up to 700 pounds and growing up to 5 feet. Most of these turtles live in coastal waters near Europe and North America. The male green sea turtle is larger in size than the female, and they also have longer tails. Both turtles have paddle shaped flippers that they use to burrow in sand and lay their eggs. One Green Sea Turtle can have up to 200 eggs.

Pacific chorus frog
The Pacific chorus frog's name derives from their auditory performance in their mating call. The two-note male can signal a mating call via the two large and round vocal sacs that inflate beneath the chin repeatedly, sounding like a chorus. The Pacific chorus frog itself is visually identified as a frog reaching up to two inches long with a black stripe extending from the nose tip to shoulder, whose color changes with the temperature and humidity.
Red-legged tree frog
The red-legged tree frog can grow past five inches given their long hind legs and elongated abdomen. The body is translucent red. This species of tree frogs live in wet environments such as wetlands and moist forest and typically breed in well shaded streams and rivers.
Columbia spotted frog
The Columbia spotted frog is typically dark brown, grey, or green and has spots on its back and sides. It lives in aquatic environments such as lakes, rivers, ponds, and marshes. They typically breed in aquatic areas such as still rivers and breed between 200 and 500 eggs at a time.
Wood frog
The wood frog is a light brown frog with dark patches over its eyes and extending down its back. These palm size frogs typically grow up to 3 inches. The Wood Frog is notorious for its verbal spring calling to attract other frogs, which is short and harsh. This frog gets its name from its habitat choice, which consists of heavily forested areas containing rocks, trees, and more. The Wood Frog however, breeds in wetlands and can breed up to 3,000 eggs at a time.
Western toad
The western toad is a large toad that has small circular or oval shaped warts down its back. This toad is often green or brown and have dark parotoid glands above the eyes. The eyes on the western toad are horizontal, unlike other toads who have vertical pupils. Western toads inhabit low elevation aquatic areas like wetlands, lake shores, wet meadows, marshes, and beaver ponds.

Northwestern salamander
''Ambystoma gracile'', the northwestern salamander, is a dark brown salamander reaching up to 23 centimeters long with dark protruding eyes and a visible parotoid glands. This salamander can be poisonous to its predators because of the excretion of a white poison through its glands when threatened. The northwestern salamander inhabits both forest and water bodies, but has a proclivity to live in burrows in the forest. The salamander also chooses to live under rocks, debris, and trees in the forest environment.
Long-toed salamander
''Ambystoma macrodactylum'', the long-toed salamander, is a salamander that occupies widespread regions, including the coastal regions of the pacific northwest. Long-toed salamanders live in a variety of habitats including sagebrush communities, coniferous forest, and in alpine meadows. Eggs and larvae have been spotted in watery areas including lakes, ponds, wetlands, springs, and puddles. An adult salamander can grow between 5 centimeters and 8.1 centimeters and are typically black with multicolored dorsal stripes and white speckling on their sides. This salamander has a long hind toe, which is where the name is derived from.
Rough-skinned newt
''Taricha granulosa'', the rough-skinned newt, is a salamander. This newt is multicolored, typically light brown on the back and yellow bellied, but can sometimes be olive green on the back. The rough-skinned newt is capable of growing up to 26.1 centimeters and will typically reach at least 12.7 centimeters. The newt's name comes from the granular and rough texture on their skin. The skin on the newt is toxic and releases a powerful neurotoxin called
