While inspecting a home Wednesday, an electric worker in Arkansas found an oddity he had never seen beyond magazines and TV: a two-headed snake.

Rodney Kelso, who works as the operations director at Woodruff Electric in Forrest City, said the snake was sunning itself when he found it outside a home on Arkansas 248.

"Fifty years on the ridge and never have seen such," Kelso said by phone Friday morning.

He put on a pair of gloves and eased the snake into a box.

A dead whale shark was found in the vicinity of Tanza Bay in Cavite province on Saturday, September 9.

Fishermen noticed the whale shark floating lifelessly. It was approximately 17 feet in length and 8 feet in diameter.

They decided to bring it to the Pandawan Fish Port in Rosario, Cavite to turn it over to the Coast Guard Station.

The Provincial Fisheries Office of Cavite is currently assessing the cause of death of the 3-year-old whale shark.

Known as 'gentle giants' of the ocean, whale sharks are the largest living fish species.

A Swede's Saturday morning hunting expedition turned out a bit more exciting than expected.

The hunter was attacked by a bear just outside of Klövsjö in the western Sweden province of Jämtland, Expressen reported.

The hunter was able to shoot and kill the bear while under attack and escape unharmed.

The incident was reported to local officials at 7.37am.

"The bear was reportedly shot when it attacked a hunter. The hunter was unscathed. Police are on hand to investigate," the local police district wrote on its website.

Giant, jelly-like blobs have been sighted off the western coast of Norway, but the identities of these mysterious objects have scientists stumped.

The blobs are about 3.3 feet (1 meter) in diameter and are translucent, except for a strange dark streak running through their center, Science Nordic reported. No one knows what they are, or what made them.

"This is a mystery, actually," said Michael Vecchione, an invertebrate zoologist at the Smithsonian Institution who has been corresponding with Norwegian researchers about the blobs. "It could be an egg mass, or something completely different, but we just don't know at this point until we get some more detailed observations."

Human antidepressants are building up in the brains of bass, walleye and several other fish common to the Great Lakes region, scientists say.

In a new study, researchers detected high concentrations of these drugs and their metabolized remnants in the brain tissue of 10 fish species found in the Niagara River.

This vital conduit connects two of the Great Lakes, Lake Erie and Lake Ontario, via Niagara Falls. The discovery of antidepressants in aquatic life in the river raises serious environmental concerns, says lead scientist Diana Aga, PhD, the Henry M. Woodburn Professor of Chemistry in the University at Buffalo College of Arts and Sciences.

"These active ingredients from antidepressants, which are coming out from wastewater treatment plants, are accumulating in fish brains," Aga says. "It is a threat to biodiversity, and we should be very concerned.

"These drugs could affect fish behavior. We didn't look at behavior in our study, but other research teams have shown that antidepressants can affect the feeding behavior of fish or their survival instincts. Some fish won't acknowledge the presence of predators as much."

If changes like these occur in the wild, they have the potential to disrupt the delicate balance between species that helps to keep the ecosystem stable, says study co-author Randolph Singh, PhD, a recent UB graduate from Aga's lab.

"The levels of antidepressants found do not pose a danger to humans who eat the fish, especially in the U.S., where most people do not eat organs like the brain," Singh says. "However, the risk that the drugs pose to biodiversity is real, and scientists are just beginning to understand what the consequences might be."

The research team also included Alicia Pérez-Fuentetaja, PhD, a professor in the biology department and Great Lakes Center at SUNY Buffalo State; Prapha Arnnok, PhD, of Ramkhamhaeng University in Thailand; and Rodjana Burakham, PhD, of Khon Kaen University in Thailand. The study was published on Aug. 16 in the journal Environmental Science and Technology.

This piglet has left farmers baffled after it was born with two heads, two noses and three eyes.

Fears have emerged for the deformed animal's survival following the strange birth on Tuesday at a pig farm in Wangcha, a village in China's Shaanxi province.

Puzzled farmers shared a recording of the mutant piglet, which was born among a litter that is not believed to have suffered the same fate.

Currently, farmers say the piglet is alive - but because of its deformities, it is not known how long it will survive.

Another "mutant piglet" with two bodies and eight legs died minutes after being born on a Chinese farm earlier this month.

A woman swimming in the lake at Bear Creek Village was the victim of an attack so rare that wildlife officials aren't certain on a cause.

She was swimming in the lake on the evening of Aug. 17 when she was bitten three times on the legs by a river otter, according to Game Commission wildlife conservation officer Phil White, who investigated the incident.

The otter followed and bit the swimmer as she made her way to shore and then left once she exited the lake, White said.

White, who declined to release the victim's name, said the swimmer sought treatment for her injuries and received a rabies vaccination as a precaution. Otters aren't uncommon in the area, White said, and the primarily aquatic animals travel through Bear Creek Village on their way to the Francis E. Walter Reservoir.

What is unusual, White added, is for an otter to attack a human.

Mystic Aquarium's Animal Rescue Team received a call on Sept. 5 about a dead humpback whale off of the Mohegan Bluffs on Block Island. The Animal Rescue and Veterinary Teams will travel to the location for sampling or necropsy as weather permits within the upcoming days, according to the aquarium.

A dead minke whale was also found Wednesday afternoon on the shores of Scarborough State Beach in Narragansett. The Animal Rescue and Veterinary Teams collected several samples and will be sent out for further analysis, however due to the advanced stage of decomposition, they will not perform a necropsy.

Mystic Aquarium said there have been a total of five whale-stranding responses so far in 2017. Although it is coincidental the two whales washed up within a day of each other, Mystic Aquarium cannot draw conclusions about the relativity.

A grizzly bear feasting on an elk carcass charged a bow hunter in Montana and attacked him, slashing a 16-inch (41-centimeter) cut in the man's head that required 90 stitches to close.

"The bear just flat-out charged us," said Tom Sommer, as he recovered in a Montana hospital on Tuesday afternoon. He said it closed the 30-foot (9-meter) distance in 3 or 4 seconds.

"It bit my thigh, ran his claws through my wrist and proceeded to attack my head," Sommer said. "I could hear bones crunching, just like you read about."

Sommer said he and a hunting partner were looking for an elk they had been calling Monday morning when his partner spotted the grizzly in the southern end of the Gravelly Range, just north of the Idaho border.

South Padre Island Fire Department Chief Doug Fowler confirmed Wednesday that a shark bit a woman near beach access 14 off of South Padre Island on Saturday.

The woman was knee-deep into the water when she felt a sharp pain on her foot, according to Fowler. Fowler says she did not suffer any life-threatening injuries.

"This is a really rare instance, and the people I've talked to can't remember another time in their lives when this happened on the island," Fowler said. "We take it very seriously--the safety of our beach goers and we work really hard in order to try to ensure their safety."

Fowler added that beach patrol will continue to stay vigilant as they check warning flags, patrol around the beach and, if necessary, move people from the beach if they're in harm's way.
