Dolphins Affected by BP Oil Spill in Grave Health Situation
The year was 2010. The world saw one of history’s worst oil spills, wreaking havoc on all sorts of marine animals in the US gulf coast and to this day, causing problems in the region.A study conducted over the years that followed the spill shows that dolphins affected by the BP oil spill are now plagued with a host of severe health problems. Close to half of the 32 dolphins observed from Louisiana's Barataria Bay in 2011 were discovered to be in grave condition, this according to the study spearheaded by National Oceanic and Atmospheric Administration, and recently published in the journal, Environmental Science and Technology.
Around 17 percent of the observed dolphin population were categorized as being in grave condition and likely to expire from poor health. A team scientists and researchers from the government, academic and private sector, conducted the study a year after the oil spill as part of the Natural Resource Damage Assessment (NRDA).
According to government estimates, the disastrous Deepwater Horizon spill churned out at least 4 million barrels of oil into the Barataria Bay in the Gulf of Mexico.
Among the health problems found in the Louisiana dolphins include extreme lung disease and low levels of adrenal stress-response hormones. One-fourth of the dolphins were also malnourished. Overall, researchers report most of the diseases observed in the Barataria Bay dolphins are rare but have been observed in dolphins exposed to oil and toxicity.

']]}High-seeking dolphins take puffer, pass it round
Dolphins are thought of as one of the most intelligent species in the animal kingdom - and experts believe they have put their ingenuity to use in the pursuit of getting "high".
In extraordinary scenes filmed for a new documentary, young dolphins were seen carefully manipulating a certain kind of puffer fish which, if provoked, releases a nerve toxin.

']]}SECRET DOLPHIN SPECIES reveals itself to stunned boffins
A previously unknown species of humpback dolphin has been blithely swimming the waters off northern Australia, according to boffins.
A research team made up of scientists from the Wildlife Conservation Society (WCS), the American Museum of Natural History and other groups set out to figure out the number of distinct types of humpback dolphins using physical features and genetic data.

']]}Dolphin calf born at Brookfield Zoo
Dolphin shows at Brookfield Zoo have been temporarily canceled to allow a male calf born Wednesday to bond with his mother.
The 40-pound calf was born to Tapeko and is about 3-1/2 feet long, according to a release from the zoo. Staff are “cautiously optimistic that the calf is healthy and doing well,” zoo spokesman Jamie Hansen said in an email.

']]}Stunning hidden similarity found between bats, dolphins
t’s a small world after all—at least from an evolutionary standpoint. A new study from Queen Mary University of London and published in Nature has found that bats and dolphins, though virtually unrelated species, independently underwent the same evolutionary process to develop the highly specialized biological system echolocation.
“We had expected to find identical changes in maybe a dozen or so genes but to see [changes in] nearly 200 is incredible,” said lead author Joe Parker in a statement. “We know natural selection is a potent driver of gene sequence evolution, but identifying so many examples where it produces nearly identical results in the genetic sequences of totally unrelated animals is astonishing.”

']]}Dolphins Memorize Better than Elephants
A new discovery has come up with findings that Dolphins have a better memory than elephants. Dolphins have undoubtedly become the most popular species for online readers. Besides, biologists and scientists see human of the sea as the most exciting creatures to study.
The study has revealed that Dolphins have a great memory. It has been provided that Dolphins can remember distinctive whistle sounds from fellow Dolphins over two decades. The memory keeping period could be higher, as a matter of fact 20 years is as far as scientists have actually been able to study so far.

']]}Dolphins can recognize whistles from old tank mates from over 20 years ago, study finds
Dolphins have long impressed people with their sharp minds and humanlike traits, such as calling each other by name, goofing off and even understanding numbers. Now a scientist has found that the mammals can recognize an old friend’s whistle, even after they have been apart for 20 years — the longest social memory ever recorded for a non-human.
In a study released Tuesday, dolphins largely ignored calls from unfamiliar dolphins but responded when an old tank mate’s signature whistle was played back to them. It didn’t matter how much time had passed since the two had last seen each other or whether they had been tank mates for only a few months: The dolphins appeared to remember a familiar whistle.

']]}Researchers Find More Evidence That Dolphins Use Names
For decades, scientists have been fascinated by dolphins’ so-called signature whistles: distinctive vocal patterns learned early and used throughout life. The purpose of these whistles is a matter of debate, but new research shows that dolphins respond selectively to recorded versions of their personal signatures, much as a person might react to someone calling their name.
Combined with earlier findings, the results “present the first case of naming in mammals, providing a clear parallel between dolphin and human communication,” said biologist Stephanie King of Scotland’s University of St. Andrews, an author of the new study.

']]}“Talking” to Dolphins
Based on a feature from Discovery News, a new “translator” on-the-works has been developed in Japan, a device primed to facilitate the communication between humans and dolphins.
The “translator” essentially reproduces the sounds made by dolphins, dealing with various pitches and frequencies, including those which dolphins utilize in communicating with each other.
Currently, researchers and scientists are eager in giving the new device a go, with plans on conducting a number of tests, touching up on the vocalizations and sounds aspect of dolphin “talk”, in relation to responses.
It is hoped that gathered research data would lead to further understanding over the dolphin language, kind of like a Rosetta Stone equivalent, which would then lead to the development of a language-translation system between human lingo and dolphin talk.
As amazing as the device is, many have raised a question pertaining to the intent of its creation. Why would humans want to talk to dolphins, anyhow?
Many are not aware of how dolphins have been helpful in undersea tasks done by dolphins, given their versatility and trainability.
They’ve been helpful in mapping undersea trenches, as well as have helped in the rigging of sonar sensors for deep sea explorations. Developing a system that allows for better interaction with them will surely make things easier for concerned parties.
That plus it just may be that dolphins have something interesting to tell human beings.
“So long, and thanks for all the fish,” maybe.

']]}Beach-goers rescue 30 stranded dolphins on Brazilian beach
At 8:00 am on March 5th, 30 dolphins became stranded on a beach in Arraial do Cabo, Brazil. Local beach-goers witnessed the "dolphin invasion," and quickly took action.
ABC explains what happened:
"The pod gets too close to the beach and is pushed into the shallow water by the waves. The dolphins, trapped in the surf, show their distress by thrashing their flippers."
The good Samaritans saved every last dolphin, pulling the slippery mammals by their tails to deeper water.

']]}Dolphin friendly Animals
Dolphin
Dolphins are one of the large sea mammals. Like most other sea animals dolphins are carnivores (meat eaters). Dolphins are intelligent and friendly animals, so some of them are trained by humans to serve as entertainment in the attractions at the circus or SeaWorld-like parks (also known as ‘dolphinaria’). While in the middle of the open sea, sometimes we see a pod of dolphins swim alongside a boat, jumping up and down to follow the boat’s wake, as if the dolphins are not afraid of humans. There are some stories we've ever heard of course about the people who were saved by dolphins at sea. Throughout history and legend, dolphins are portrayed as helpful and protective of people. Unfortunately, they are also considered as food—killed in harpoon drives like in Taiji, Japan and in the Faroe Islands.
