Dolphins speak "baby talk" to offspring

Have you ever noticed that when adults speak to babies or small children, they speak in a distinctively specific manner? As if by instinct, they speak in a high-pitched voice, with clear pronunciation and longer pauses between words.

It seems that this “baby talk” is not reserved for humans. Researchers have discovered that dolphins too indulge in baby talk—by changing their characteristic whistles and frequencies—when they communicate with their offspring.

Ancestor of early toothed whales had "weird" teeth

Today, researchers are using the fossils of the Olympicetus thalassodon an early toothed whale which existed around 26.5 and 30.5 million years ago, to better understand the early history and diversification of modern dolphins, porpoises and other toothed whales.

Iceland suspends controversial whale hunt

“I have taken the decision to suspend whaling” until 31 August, food minister Svandis Svavarsdottir said in a statement, after a recent government-commissioned report concluded the hunt does not comply with Iceland’s Animal Welfare Act.

The report which provided a video showing a whale being hunted for five hours concluded the killing of whales during the hunt took too long.

Animal rights groups and environmentalists hailed the decision, with the Humane Society International calling it “a major milestone in compassionate whale conservation”.
