Clymene Dolphin Natural Hybridization
2014-01-09 12:44:22

Lee Rannals for redOrbit.com - Your Universe Online Natural hybridization between two dolphin species likely helped to bring about the mysterious clymene dolphin, according to a study published in the open-access journal PLOS ONE. Researchers from several institutions found in a molecular analysis that spinner dolphins and striped dolphins helped create the clymene dolphin. Questions about the clymene dolphin’s origins have been unanswered for many years, so the team from the...

Maps May Offer Dolphins Protection From Tourist Activities

Brett Smith for redOrbit.com - Your Universe Online As we all know, starting your day without a good night´s rest can impact your performance and ability to think. The same applies to spinner dolphins around Hawaii who may not be getting enough rest because of tourists cruising the waters in search of the famously sociable and acrobatic mammals. But a new plan published in PLoS ONE could give the dolphins their space without closing off the waters to tourists completely....

Prey Distribution, Not Biomass, Key To Marine Food Chain
2012-05-03 03:30:03

A new study has found that each step of the marine food chain is clearly controlled by the trophic level below it — and the driving factor influencing that relationship is not the abundance of prey, but how that prey is distributed. The importance of the spatial pattern of resources — sometimes called “patchiness” — is gaining new appreciation from ecologists, who are finding the overall abundance of food less important than its density and ease of access to...

Unique Whistles Allow Dolphins To Greet Each Other
2012-03-01 05:45:52

Marine biologists have discovered that bottlenose dolphins use whistles to greet other members of their species. The researchers in Scotland said they made recordings of dolphins swimming in St. Andrews Bay in the summers of 2003 and 2004 by using hydrophones. They said when the group of dolphins met up, they swapped whistles that outwardly sounded the same. "The whistle exchange is more of a greeting ceremony that communicates a friendly intention and is perhaps not needed to...

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...

Fishing activities are stunting population growth of a type of Pacific Ocean dolphin despite dolphin-safe practices, U.S. university researchers said. The study by Scripps Institution of Oceanography at the University of California-San Diego revealed negative impacts from fishing activities remain, despite adoption of regulations and agreements designed to reduce dolphin deaths from by-catch in which animals are caught unintentionally along with the intended targets. The research by the...

2 dolphin stocks may be recovering from tuna fishing practicesThe numbers of Northeastern offshore spotted and eastern spinner dolphins in the eastern tropical Pacific Ocean are increasing after being severely depleted because of accidental death in the tuna purse-seine fishery between 1960 and 1990, according to biologists from NOAA's Fisheries Service."These estimates are encouraging because they are consistent with what we would expect to see if these stocks are recovering, now that...

Clymene Dolphin, Stenella clymene
2012-06-20 11:17:59

The Clymene dolphin (Stenella clymene) is a dolphin that is native to the Atlantic Ocean. It was once known as the short-snouted spinner dolphin. Although its range is not fully understood, specifically the southern portions, it does prefer tropical and temperate waters. Its range begins in New Jersey, stretching east-south-east to southern Morocco, and it is thought that the southern area of its range beings near Angola and stretches to Rio de Janeiro. It prefers habitats within deep water,...

The Bottlenose Dolphin (Tursiops truncatus) is the most common and well-known dolphin species. It inhabits warm and temperate seas worldwide and may be found in all but the Arctic and the Antarctic Oceans. Physical description Bottlenose Dolphins are grey, varying from dark grey at the top near the dorsal fin to very light grey and almost white at the underside. The salt water makes them hard to see both from above and below when swimming. The elongated upper and lower jaws give the...

The Spinner Dolphin (Stenella longirostris) is a small dolphin found in offshore tropical waters around the world. It is famous for its acrobatic displays in which they will spin longitudinally along their axis as they leap through the air. Taxonomy The Spinner Dolphin is sometimes referred to as the Long-snouted Spinner Dolphin, particularly in older texts, to distinguish it from the similar Clymene Dolphin, which is often called the Short-snouted Spinner Dolphin. John Gray discovered...

The Pantropical Spotted Dolphin (Stenella attenuata) is a species of dolphin found in all the world's temperate and tropical oceans. The species was beginning to come under threat due to the killing of millions of individuals in tuna. The 1980s saw the rise of "dolphin-friendly tuna [capturing methods]" in order to save millions of the species in the eastern Pacific Ocean. Taxonomy John Gray first identified the species in 1846. Gray's initial analysis included the Atlantic Spotted...
