Marine scientists are debating whether the 80-plus dead bottlenose dolphins that have washed up along the U.S. Gulf Coast since January died from last year's oil spill or of a winter cold snap. The National Oceanic and Atmospheric Administration (NOAA) declared "an unusual mortality event" last week when the death toll of the dolphins that washed up in Louisiana, Mississippi, Alabama and Florida coasts reached nearly 60. Since then, the death toll has climbed to at least 82. The dolphins have...

According to Florida researchers, dolphins are able to imitate each other, even blindfolded. The researchers at the Dolphin Research Center in the Florida Keys said in a study published in the International Journal of Comparative Psychology that their blindfolded dolphin used other senses to figure out what the other dolphin was doing and copy it. The dolphin is a 7-year-old bottlenose dolphin named Tanner. The researchers said they hope to conduct further studies to "map the dolphin mind"...

Two distantly related species of dolphin -- the Guyana and the Bottlenose -- often can be found socializing in waters off the coast of Costa Rica, according to a recent BBC report. Both species of dolphin make distinct sounds, but when they meet up, they change the way they communicate with each other by using a transitional language. It raises possibilities that the two species are communicating in some way. Details of the finding are published in the journal Ethology. It is not clear to...

Scientists at Georgetown University, the National Aquarium and the University of Queensland are the first to extract DNA from dolphin blow (breath exhalations). The researchers found that blow-sampling, which involves collecting exhalations from the blowholes of whales, dolphins and porpoises, could be developed as a less invasive method for DNA collection. Their findings are explained in the Aug. 25 edition of the online journal PLoS ONE in an article titled "Thar She Blows! A Novel Method...

Nearly 60 pilot whales have died after becoming stranded on a beach in northern New Zealand, conservation authorities reported Friday.There were 73 total whales discovered on the beach mid-morning and the Department of Conservation's Carolyn Smith said the whales most likely beached overnight, which is why so many died before rescue operations were launched.Of the 73 pilot whales, 15 have survived, but are reported to be in "poor condition." Volunteers are making another attempt to rescue the...

The evolutionary mystery of menopause is a step closer to being solved thanks to research on killer whales. A study by the Universities of Exeter and Cambridge has found a link between killer whales, pilot whales and humans "” the only three known species where females stop breeding relatively early in their lifespan. Despite very different social structures between the three species, the research shows that in each case females become increasingly genetically related to those...

Scientists are now saying that marine mammals are not only smarter than previously thought, but many also share several attributes once claimed to be exclusively human. Cetaceans, an order of more than 80 whales, dolphins and porpoises, have the ability to express self-awareness, suffering and have social cultures with high mental abilities, say marine biologists. If the notion is true that whales are intelligent and sentient beings, it would threaten to destroy the assumption that they are...

DENVER, June 3 /PRNewswire/ -- For times of wildlife health emergencies, Morris Animal Foundation (MAF) established the Betty White Wildlife Rapid Response Fund to give wildlife researchers timely monetary aid to respond to unexpected events, such as natural disasters and emerging diseases, that result in the immediate need for animal health research. The first grant provides researchers with immediate funds to begin important research on the long-term effects of the 2010 oil spill in the...

The iPad might offer a new solution for scientists wishing to communicate with dolphins. Dolphin researcher Jack Kassewitz is using an iPad to interact with a 2-year-old dolphin named Merlin.  Kassewitz says this could potentially not only allow humans and dolphins to interact, but also be easily used as a universal translator for humans. "For several years, we've recognized that part of the problem in creating an artificial language between humans and dolphins has been the speed of...

Experts from the National Oceanic and Atmospheric Administration (NOAA) have discovered genetic evidence that there are multiple species of killer whales. Lead researcher Phillip Morin and his colleagues at the NOAA's Southwest Fisheries Science Center in La Jolla, California, took tissue samples from 139 orcas from the North Atlantic, the North Pacific, and Antarctica. By analyzing the mitochondria of each, they confirmed the existence at least three distinct killer whale species. According...

Cetology
2013-10-02 11:21:29

Cetology is a branch of marine mammal science that studies about eighty species of dolphins, whales, and porpoise, all of which are classified within the Cetacea order. Cetologists, who practice cetology, work to understand the distribution, development, behavior, and other aspects of cetaceans. The study of cetaceans began in the Classical era. About 2,300 years ago, Aristotle documented details about some cetacean species, calling them mammals, while traveling on the Aegean Sea with...

Indo-Pacific Bottlenose Dolphin, Tursiops aduncus
2013-09-19 11:24:25

The Indo-Pacific bottlenose dolphin (Tursiops aduncus) is one of three recognized species of bottlenose dolphin that can be found in the waters near southern Australia, South China, and India. Its range also includes the Red Sea and the eastern coastal areas of Africa. All bottlenose dolphins were classified as one species, the common bottlenose dolphin or T. truncates, until 1998 when the Indo-Pacific bottlenose dolphin was found to be distinct. This species is distinct from other bottlenose...

Burrunan Dolphin, Tursiops australis
2013-09-19 11:08:29

The Burrunan dolphin (Tursiops australis) is one of three recognized species of bottlenose dolphin. It can be found in two areas of Victoria, Australia. One population can be found in the Gippsland Lakes, where about 50 reside, and one in Port Phillip, where about 100 individuals reside. Haplotypes of the Burrunan dolphin have been discovered in an area extending from the Spencer Gulf waters west to St. Francis Island. Because of its low numbers, it is thought to deserve protection from the...

Hourglass Dolphin, Lagenorhynchus cruciger
2013-08-16 10:45:47

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...

Long-Beaked Common Dolphin, Delphinus capensis
2013-06-22 16:27:01

The long-beaked common dolphin (Delphinus capensis) is a species within the Delphinus, or common dolphin, genus that can be found in a fragmented range within tropical and warm temperate habitats. Its range includes western and southern areas of Africa, central California and Mexico, coastal regions of Peru, Taiwan, Korea, Japan, a large portion of western South America. The long-beaked common dolphin was not considered a distinct species until the 1990’s, along with all other species of...
