Whales have accents and regional dialectsWhen they dive together, sperm whales make patterns of clicks to each other known as "codas". Recent findings suggest that, not only do different codas mean different things, but that whales can also tell which member of their community is speaking based on the sound properties of the codas. Just as we can tell our friends apart by the sounds of their voices and the way they pronounce their words, different sperm whales make the same pattern of clicks,...

Like humans, whales can receive sunburn-like effects from overexposure to ultraviolet radiation (UVR), according to a new study printed in this week's edition of Proceedings of the Royal Society B. Researchers, including Laura Martinez-Levasseur of the Zoological Society of London (ZSL), made the discovery after studying blue whales, fin whales, and sperm whales in the Gulf of California. They also analyzed high-resolution photographs of blisters and damaged areas in skin samples. They found...

Genomic record matches fossil record in the whales' common ancestor, say UC Riverside biologists In contrast to a toothed whale, which retains teeth that aid in capturing prey, a living baleen whale (e.g., blue whale, fin whale, humpback, bowhead) has lost its teeth and must sift zooplankton and small fish from ocean waters with baleen or whalebone, a sieve-like structure in the upper jaw that filters food from large mouthfuls of seawater. Based on previous anatomical and fossil data studies,...

Fossilized remains of a giant, prehistoric sperm whale that lived 12 million years ago and had teeth and jaws so large it preyed on whales more than half its size have been discovered in Peru's Pisco basin, scientists reported Wednesday. The Leviathan melvillei, named after "Moby Dick" author Herman Melville, grew up to 60 feet long, and had interlocking, tusk-like teeth 14 inches in length for killing and capturing prey, the scientists said. Although paleontologists have long suspected a...

A study released on Wednesday reveals that Southern Ocean sperm whales' feces are an unexpected ally in the fight against global warming. The cetaceans have been previously fingered as climate culprits because they breathe out carbon dioxide (CO2), the commonest greenhouse gas. However, according to the paper published in the British journal Proceedings of the Royal Society B, this is only part of the picture. Australian biologists estimated that the 12,000 sperm whales left in the Southern...

Wildlife officials said that more than 40 sperm whales have died after a pod of about 50 became stranded off southern Australia.  Rescuers have been trying to keep the surviving whales alive by pouring water over them. The whales are trapped on a sandbar about 500 feet offshore from Perkins Island on the northwest coast of Tasmania. Because of the whales' immense size, and that the area is only accessible by sea, the rescue is proving to be a difficult one. Liz Wren, a spokeswoman for...

Illusive mammals such as the beaked whale are hardly seen, mysterious, and obscure, and yet they have become the focus of new studies due to the harm that military sonar systems seem to cause them. "There's not much known about these creatures - where they live, their lifestyle," says Ted Cranford from San Diego State University. "In fact, they might be the least understood group of large mammals on Earth." This summer, the research yacht Song of the Whale, operated by the International...

Under the sea, predatory pilot whales take part in high-speed chases as they track down their prey.The cetaceans have been observed reaching such high speeds that scientists have likened their hunting technique to that of the cheetah, according to researchers in the Journal of Animal Ecology.Their findings may dispel the common notion of whales as large slow creatures.The research is the first to document the remarkable "burst-speed" of the pilot whale."As far as we know, no other whale has...

By Alister Doyle, Environment Correspondent OSLO (Reuters) - A ferocious-looking fossil with sharp teeth found in Australia shows that ancestors of today's toothless blue whales were not all "gentle giants," a report said on Wednesday. The 25 million-year-old fossil is of an early type of baleen whale, a group including modern humpback whales, minke whales and blue whales that feed via baleen, comb-like plates in their mouths that filter plankton from sea water. "This bizarre, new baleen...

The Pygmy Sperm Whale (Kogia breviceps) is one of three species of whale in the sperm whale family. They are not often sighted at sea and most of our understanding of the creatures comes from the study of washed-up specimens Taxonomy There has been debate and differing opinion as to the correct classification of the Pygmy and Dwarf Sperm Whales. The two were widely considered to be the same species, until 1966, when a scientist at the Smithsonian Institute definitively diagnosed them as...

The Sperm Whale (Physeter macrocephalus) is the largest of all toothed whales and is believed to be the largest toothed animal to ever inhabit Earth, measuring up to 60 ft (18 m) long. (The baleen blue whale is larger, and invertebrates such as the Lion's Mane Jellyfish or the Portuguese Man of War may be longer.) The whale was named after the milky-white substance spermaceti found in its head and originally mistaken for sperm. The Sperm Whale's enormous head and distinctive shape, as well as...
