Chemicals produced by humans have been found in deep-sea squid and other creatures, further evidence that contaminants make their way deep into the marine food web, scientists said Monday. Researchers found a variety of chemical contaminants in nine species of cephalopods, which include octopods, squids, cuttlefishes and nautiluses. These species are food for dolphins, narwhals, killer whales and other toothed whales. The researchers collected nine species of cephalopods up to a...

Every autumn and winter, hunters from this craggy Japanese fishing village corral thousands of dolphins into a tiny, isolated cove and kill them for meat and fertilizer, turning the water red with their blood. And every year, foreign animal rights protesters converge on the town, interfering with the slaughter, clashing with fishermen and broadcasting grisly photographs of the slayings around the world - all without stopping the hunt. Now, Japan's dolphin hunters face a new, powerful...

The Zoological Society of London said it hoped preliminary results on what killed the Northern bottlenose whale would be available Wednesday. Paul Jepson, who has conducted government-funded research into why dolphins and...

Blainville’s beaked whale (Mesoplodon densirostris), also known as the dense-beaked whale, can be found in a large range that includes the warm and tropical waters of all oceans. It prefers to reside at depths between 1,600 and 3,000 feet and does not migrate. This species received its common name from Blainville, the man who classified it as Delphinus densirostris after studying a description of a piece of one individual’s nose located in the Paris Museum. In 1846, John Edward Gray...

The hourglass dolphin (Lagenorhynchus cruciger) is a rare species that can be found in Antarctic and subAntarctic waters. Most sightings of this species have been made in the southern waters near the Shetland Islands, off the coast of Tierra del Fuego, Argentina, and in the southern waters near New Zealand. It is thought that this dolphin does not congregate in large numbers in any area of its circumpolar range. Qouy and Galmard first recognized the hourglass dolphin as a new species in...

The short-beaked common dolphin (Delphinus delphis) is a species that can be found in warm temperate and tropical waters. Its range is larger than that of the long-beaked common dolphin and includes the Mediterranean and Caribbean Seas, but it is not thought to occur in the Indian Ocean. This species is classified within the Delphinus genus along with the long-beaked common dolphin. Both of these species were classified under one species, named D. delphis, until it was found that both were...

The Melon-headed Whale (Peponocephala electra; other names are many-toothed blackfish and electra dolphin) is a cetacean of the oceanic dolphin family (Delphinidae). It is closely related to the Pygmy Killer Whale and the Pilot Whales, and collectively these dolphin species are known by the common name blackfish. The Melon-headed Whale is widespread throughout the world's tropical waters, although not often seen by humans on account of its preference for deep water. Taxonomy On account...

The Australian Snubfin Dolphin (Orcaella heinsohni) is a recently recognized species of dolphin first described in 2005. It is closely related to the Irrawaddy Dolphin, and closely looks like it. Until very recently it was thought to be an Irrawaddy dolphin. However, the Australian Snubfin Dolphin is three-colored, while the Irrawaddy dolphin only has two colors on its skin. Also the skull and the fins show minor differences between the two species. The discovery of a new mammal is...
