Latest Toothed whales Stories
New study turns a long-accepted evolutionary assumption on its head, finding that whale pelvic bones play a key role in mating.
New study estimating population genetic structure of little-known dolphins inhabiting Western Australia's north coast highlights vulnerability.
Scientists monitored Cuvier's beaked whales' record-breaking dives to depths of nearly two miles below the ocean surface and some dives lasted for over two hours.
Researchers say they have discovered a new species of beaked whale after studying several stranded cetaceans on remote tropical islands in the Indian and Pacific Oceans. The first of these new species was discovered more than 50 years ago.
In December, the National Marine Fisheries Service authorized Navy sonar training exercises off the coasts of Hawaii and California through 2018. This authorization came despite admittance by the Navy that the work will kill up to 155 marine mammals and harm numerous others.
The National Oceanic and Atmospheric Administration announced unsettling and unfortunate news this week centered on the bottlenose dolphin and Cetacean populations on the east coast of the United States. We are witnessing the most unprecedented stranding and die-off of these creatures in our recorded history.
The most common and well-known of their kind, bottlenose dolphins are famous for their roles in movies, television and water parks everywhere. And to the layperson's eye, one bottlenose dolphin might not look any different from another. When you look closer, however, perhaps genetically, there are telltale differences in each individual.
A new study of mass whale strandings has shown that despite previous theories, family ties do not appear to play a role in this bizarre phenomenon. The true cause, however, remains a mystery.
Traveling into uncharted territory in search of food can be a dangerous undertaking, but some bottlenose dolphins may benefit by moving through their habitat with relatives who may be more experienced or knowledgeable.
Scientists found a group of sperm whales and an unlikely companion by their side: a dolphin with a spinal deformation.
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...
