Endangered Parasites

Animals Climate Change Ecology

Parasites are creatures that live in or on a host animal. Some people dislike parasites because they can be slimy, and they often cause harm to their host, but they can also play a key role in supporting ecosystems. Now, climate change is threatening the survival of host animals such as elephants and polar bears, putting their parasites at risk, too. Listen to hear about the surprising life cycle of a flatworm and learn what scientists are doing to try to save important parasites.

Searching for Bowhead Whales

Animals Oceans Marine Biology

The bowhead whale lives its entire life - which amazingly can span over 200 years - in the frigid Arctic waters near the North Pole. The bowhead whale is unlike most other whales as it doesn’t seasonally migrate in search of warmer waters. A thick layer of blubber and the ability to hold its breath for up to 30 minutes makes it possible for bowhead whales to live in the deep, freezing water. Listen to hear even more incredible facts about this unique ocean mammal.

Arctic Foxes Use Good Camouflage

Animals Biology Diversity and Adaptation

Arctic foxes may be small, but they undergo powerful adaptations that help them survive in the snowy tundra, one of the planet’s most unforgiving biomes. One of their most important adaptations is the gift of camouflage: Arctic foxes’ fur changes color depending on the season. In winter, these animals grow dense white fur that keeps them warm and camouflages them in their snowy surroundings. In spring, they molt to reveal thinner, gray-brown fur to better blend in after the snow has melted away. Listen to hear more about this and other incredible adaptations of the Arctic fox.

Solitary Wolverines

Animals Biology

Wolverines are fierce predators and scavengers that live in the remote forests near the Arctic Circle. As these solitary animals need at least 500 square kilometers of space each and can travel vast distances each day, they are very difficult to spot in the wild. Wolverines play an important role in the ecosystem as they scavenge the carrion left behind by other predators. Listen to hear more about this elusive mammal, including why people walking through the forest shouldn’t worry about being attacked by one.
