Right whales have been shown to be affected by noise pollution.

The increasing use of the sea for human activities has resulted in a dramatic rise in noise levels.
Sperm whales, like many other species, use echolocation which can be hampered by noise.

We tend to think of the oceans as quiet, when in fact they're anything but. Noise is the "forgotten pollutant", but the good news is that unlike many other pollutants it can be switched off if we try.
Humpbacks can use their fins as weapons against killer whales.
Humpback whales have been spotted fending off killer whales from attacking other species. But this kind of interspecies altruism raises an evolutionary conundrum.
What are the oldest living animals on the planet?
School of thought.
Understanding this will boost conservation efforts.
Some dolphins live close to the shore, where they regularly encounter humans. This is affecting their numbers.
Globally, a quarter of whale and dolphin species are endangered. Though South African dolphin populations are generally in good heath, the humpback dolphin is cause for concern.
This could be your lucky day.
Highly prized and extremely rare, it's hard to tell if you've stumbled on this piece of sperm whale 'product'.
DNA analysis reveals that there are three populations of Antarctic blue whales.

Antarctica's blue whales all feed in the same place. But a new genetic analysis suggests they are actually three separate populations that breed in different parts of the globe.
The Thames whale: a rather lost northern bottlenose.
It didn't turn out well for the whale who went to Westminster, but others have made a happy home in British waters.

The tale of the vengeful whale that took out the Essex, a whaling-ship, has now been adapted in true swashbuckling style.
Can Australians stomach a small, scientifically-sound whale harvest?

The clash between Australia and Japan over whaling is undermining science-based environmental law.
Japan will kill Minke Whales in the Southern Ocean under the new whaling program.

Japan's whaling fleet will leave port today to resume whaling in the Southern Ocean as part of its new scientific program, NEWREP-A.
Right whales pass on the knowledge of their migration routes.
Why are some southern right whale populations not recovering as fast as we hoped? The answer may be in their migrations.
Coelacanth: extinct for millions of years … then found alive.

Sometimes extraordinary species really do appear to come back from the dead.
A sorry end: beached whales in Flinders Bay.
They are among the most intelligent creatures on the planet, but family ties can lead them into danger
Humpback whale populations have leapt on both Australia’s east and west coasts.

Chalk it up as a rare conservation win: humpback whales have bounced back so strongly since the whaling era that there is no longer a need to include them on Australia's official threatened species list.
Loggerhead turtle populations are facing a brighter future, but many other species are still in decline, while for others there are no data at all.

The Great Barrier Reef is home to some 1,600 species of bony fish, 130 sharks and rays, and turtles, mammals and more. Most have had no population monitoring, meaning we don't know how well they are faring.
Japan will need to try again to justify killing whales for scientific research.

Japan's proposed new program to kill whales for science has been rejected by an international expert panel.
Hefty problem: a local council was left with a huge clean-up bill after a dead whale washed up in Perth last year.

Dead whales can cost beachside ratepayers a lot to clean up. The alternative is to tow them away before they wash up - but the legal question of who does the job is far more complex than it sounds.
Natural History Museum
The Natural History Museum’s plan to remove “Dippy”, the cast of a diplodocus skeleton, from its entrance hall, and replace it with a genuine skeleton of a blue whale has been met with outrage. The #savedippy…
