A new study shows that the population of false killer whales in waters close to Hawaii seems to have declined significantly over the past 20 years, the Associated Press reported.The report said that the dolphin species are likely dropping due to the declining food supplies and their tendency to get caught and injured on the longline fishing lines from commercial fishing vessels that can span 50 miles.Environmental activists recently sued the federal government for allegedly failing to prevent...

Researchers report finding a stronghold for the Irrawaddy, one of the world's rarest freshwater dolphins, deep in the Bangladesh jungles. Scientists counted nearly 6,000 of the dolphins in the South Asian country's Sundarbans mangrove forest adjacent to the Bay of Bengal, the Wildlife Conservation Society said in a release. Before the find by the Wildlife Conservation Society there were only a few hundred of the Irrawaddy believed alive. This discovery gives us great hope that there is a...

Researchers say global warming is bringing food stocks closer to shore, causing the mass beaching of whales along Australia's coast, the AFP reported.Last week, nearly 90 long-finned pilot whales and bottlenose dolphins were beached along the Hamelin Bay on Australia's west coast in the last month.Experts say it took the total number of beached cetaceans in southern Australia beyond 500 in the past four months alone, including a single stranding of almost 200 on King Island.The...

Dolphins are the foodies of the ocean, deemed so because of their specific and complicated measures to purge cuttlefish of ink and bone, Australian scientists announced on Friday. A female Indo-Pacific bottlenose dolphin was seen prepping her cuttlefish for consumption in the Spencer Gulf, located in Australia. "It's a sign of how well their brains are developed. It's a pretty clever way to get pure calamari without all the horrible bits," Mark Norman, the curator of mollusks at Museum...

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...

A new study of pygmy killer whales shows that those living off Hawaii tend to stay close to the islands and don't swim out to the open ocean, researchers said. One of the least understood marine mammal species, there are very few of the whales (probably less than 200 individuals) in this distinct pygmy killer whale population off the islands. The research published Tuesday in the journal Marine Mammal Science suggests the population's limited number makes it more vulnerable than other whale...

CUMBRIA, England and FORT LAUDERDALE, Florida, December 30 /PRNewswire/ -- - Key Words: Dolphin, Cetacean, Acoustics, Holography, Language, CymaScope In an important breakthrough in deciphering dolphin language, researchers in Great Britain and the United States have imaged the first high definition imprints that dolphin sounds make in water. The key to this technique is the CymaScope, a new instrument that reveals detailed structures within sounds, allowing their...

Marine biologists say that many female bottlenose dolphins in Western Australia's Shark Bay area spend a disproportionately large amount of time using sponges to root for prey on the ocean floor. They say this causes some dolphins to work longer hours than others for their food. Scientists say the female bottlenose dolphins living in 30- to 50-foot-deep channels off Australia's western coast that bury their noses in sponges and use them as tools to root through the sandy ocean floor for...

Australian authorities reported on Sunday that at least 150 whales have died after being stranded on Tasmania's west coast. The long-finned pilot whales were discovered on Saturday, badly injured by jagged rocks. The body count was affirmed on Sunday to be 150, double the original estimate of 80 on Saturday. An official said that rescuers did managed to save 30 whales, which were trapped in shallow reefs, by using a small safety boat to steer them to deeper water. Whales pass Tasmania as they...

Despite broad "dolphin safe" practices, fishing activities have continued to restrict the growth of at least one Pacific Ocean dolphin population, a new report led by a researcher at Scripps Institution of Oceanography at UC San Diego has concluded.Populations of dolphins in the Eastern Pacific were expected to increase in abundance after successful regulations and agreements were enacted to reduce dolphin deaths as a result of fishing "bycatch," cases in which animals are caught...

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...

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...
