Wolves are amazing hunters, so they tend to be apex predators wherever you find them...including one region in Alaska where these land-based predators sit atop a marine food web.

SciShow News takes you to the depths of the Earth, where the world’s most abundant mineral is found, and to the Arabian Sea, where a strange population of whales has been living in isolation for 70,000 years!

Marine biologist Erica Staaterman is tuned in to the sounds of the undersea world. She records and analyzes the noise of life underwater, and as a result can tell you what a lobster sounds like, or a mantis shrimp (it rumbles).

Discover the incredible speed, strength, and feeding habits of this apex predator, as well as its unique anatomy and adaptations for survival. Learn about the life cycle and habitat of great white sharks, and the important role they play...

With an ever increasing appetite for fish how can we balance our daily demand with a sustainable supply? Ten per cent of the world's population depend on the fishing industry for their livelihoods. However, global overfishing has...
