A humpback whale mother and calf embark on an epic journey from tropical coral paradises to storm ravaged polar seas. Newly discovered coral reefs in Indonesia reveal head-butting pygmy seahorses, flashing 'electric' clams and bands of sea kraits, 30-strong, which hunt in packs. Elsewhere plagues of sea urchins fell forests of giant kelp. Huge bull fur seals attack king penguins, who despite their weight disadvantage, put up a spirited defence.
Plants are able to communicate with each other in ways we are only now beginning to understand. Some plants can differentiate between roots of their "family" and roots of other kinds of plants when they touch underground. See how plants "talk" to each other and find out what they talk about!
Who are you going to call when beavers are behaving badly? Well, if you live in Jackson Hole, Wyoming, Drew Reed is the go-to 'beaver buster'. Drew works as a wetland conservationist, helping to keep the peace between beavers and people. These busy rodents are incredibly industrious - felling trees and building dams are two of their favourite occupations. This can be good news in the wild, helping create rich habitats for a variety of wildlife, but in back yards it can spell disaster. A beaver is more than capable of bringing down a tree large enough to damage property, and their dam building can result in flooded homes. Drew must do what he can to steer beavers away from trouble and stop their so-called bad behaviour.
