2012-04-24 04:06:52

Jason Farmer for RedOrbit.com Scientists believe they have made the very first sighting of an adult white killer whale, according to various media reports. The adult male was spotted off the coast of Kamchatka in eastern Russia. Scientists have nicknamed the whale Iceberg. The whale appears to be in good health and is living with a normal pod. Occasionally, white whales of other species are seen, but prior to this sighting, the only known white orcas have been young. The...

Reasons Still Unclear For Massive Dolphin Deaths In Peru
2012-04-23 10:42:05

Environmentalists and local authorities are working together to discover why nearly 900 dead dolphins have washed up on the northern coast of Peru so far this year. Gabriel Quijandria, Deputy Environment Minister of Peru told the Associated Press (AP) in an interview that their investigation is still underway but their hope is to complete research by the end of this week. About 90% of these 877 washed up dolphins were the common, long-nosed varieties, while the rest were Burmeister...

Toothless Whales Use Fat To Listen
2012-04-19 05:52:47

Scientists have long understood the way dolphins and toothed whales have been able to hear underwater. These animals have a special type of fat surrounding their jaws which can relay sounds from the ocean to their ears. Now, thanks to a new study, scientists are able to understand how their toothless grazing cousins, the baleen whales are able to hear without these sound-enhancing jaws. Toothed whales and dolphins are able to use their jaws in conjecture with echolocation in order to...

Dolphins behave uniquely. On the one hand, male dolphins form alliances with others; on the other hand, they live in an open social structure. Anthropologists from the University of Zurich detected this unusual behavior in the animal kingdom in dolphins in Shark Bay, Australia. Male dolphins in Shark Bay, Australia, display the most complex group behavior of all mammals after us humans. Studies in the 1990s revealed that two to three male dolphins cooperate very closely with each other to...

Ecologists in New Zealand have shown for the first time that Marine Protected Areas — long advocated as a way of protecting threatened marine mammals — actually work. Their study, based on 21 years' monitoring and published today in the British Ecological Society's Journal of Applied Ecology, reveals that a marine sanctuary off the coast of Christchurch has significantly improved survival of Hector's dolphins — one of the rarest dolphins in the world. Covering 1170 km2 of...

Deepwater Horizon Spill Left Behind Sick Dolphins
2012-03-28 11:29:01

NOAA marine mammal biologists are reporting signs of poor health in bottlenose dolphins in the Gulf Coast. The dolphins, located in Barataria Bay, may be experiencing poor health due to exposure from the Deepwater Horizon oil spill of 2010. NOAA biologists took comprehensive physicals of 32 live dolphins from Barataria Bay in the summer of 2011 and found many troubling health concerns, such as anemia, low blood sugar, and low weight. The biologists also found more than half of the...

In the dark world of the underwater ocean, whales need to locate their prey accurately and quickly. In low-vision conditions whales use echolocation to find fish swimming nearby, and now it has been discovered that they can focus their acoustical “vision” to accurately located slightly differing objects. For this study, Laura Kloepper from the University of Hawaii and her her PhD supervisor, Paul Nachtigall, utilized the help of Kina the False Killer Whale, a species related to...

False killer whales focus echolocation clicks Hunting in the ocean's murky depths, vision is of little use, so toothed whales and dolphins (odontocetes) rely on echolocation to locate tasty morsels with incredible precision. Laura Kloepper from the University of Hawaii, USA, explains that odontocetes produce their distinctive echolocation clicks in nasal structures in the forehead and broadcast them through a fat-filled acoustic lens, called the melon. 'Studies by other people showed...

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...

The finless porpoise (Neophocaena phocaenoides) can be found in the coastal waters of Asia. Its range includes China, Indonesia, Korea, India, Japan, and Bangladesh. Its western range extends from the coast if India to the Persian Gulf and a distinct freshwater subspecies resides in the Yangtze River.

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...
