Snakes play important roles in ecosystems, but they also terrify some people. That fear has led to many myths about snake behavior.

To get to the bottom of some of the assumptions about snakes in the United States and separate fact from fiction, Live Science talked to several snake experts. Here are some commonly held beliefs about snakes and whether they're true or false.

Stortroen, an 82-year-old retired insurance claim center manager from St. Paul, Minn., has joined research outings in places ranging from Australia to South Africa. This was his first time assisting scientists in the Mojave Desert.

"I enjoy the teamwork. I enjoy working with nature," he said, pausing beside boulders while the group took a break and pulled out their water bottles.

Stortroen was one of 15 Earthwatch volunteers — American, British and Canadian — who helped with the research earlier this month in Joshua Tree National Park. The volunteers split up with park biologists and UC scientists to conduct surveys of plants, count birds and record the numbers of lizards and other reptiles.

Northern New England's annual amphibian migration is always perilous, but critters that cross roads to breed are facing an additional challenge this year: a delayed start after the long winter. Every spring, several species of salamanders and frogs travel to vernal pools —temporary bodies of water created by melted snow—to mate and lay eggs, and the resulting offspring need several months to develop and grow legs before the pools dry up in summer. Wildlife officials say the migration is running a week or two behind this year, cutting into that critical development time. That could affect millions of animals across Vermont, Maine, and New Hampshire, says Eric Orff, a wildlife biologist with the National Wildlife Federation.

"Sandesh was well informed about the dangers of a snakebite. He very well knew sleeping causes venom to spread rapidly all over the body and hence he did not sleep," Nayak said. Sumalatha said the snake was not poisonous, but had caused a deep wound around the boy's knees. "On giving necessary treatment, we found out the boy was not bitten by poisonous snake, but it had caused deep wound around his knee.

As he responded to the treatment quickly, Sandesh was discharged from the hospital after he recovered fully, the doctor said. The boy, on his arrival to the hospital, refused to set the snake free from his bag, but after the treatment it was released into a nearby forest, the boy's father said.

Moving quickly, the top half of the snake ascends the trunk, while the bottom half of it stays coiled lower down.

Wrapping its top half around the tree, the snake then brings the rest of its body up to where its head is and begins tightly coiling itself around the trunk once more.

Once entirely wrapped around the middle section of the tree, the snake again lifts its head and ascends vertically a metre or so.

The recovery plan focuses on alleviating the threat of habitat loss and fragmentation by permanently protecting breeding ponds and their adjacent uplands through acquisition and conservation easements. Because the majority of the remaining habitat for the Santa Barbara County California tiger salamander is on privately owned lands, habitat-based conservation efforts will require the cooperative efforts of both local agencies and private partners.

"Because we’ve already destroyed so much of their natural habitat, recovering and protecting the places these unique tiger salamanders need to survive won’t be easy," said Loda. "But we can’t afford to lose this special amphibian, so I hope federal, state and local agencies as well as developers will all step up to support the hard work of recovery."

Although Santa Barbara California tiger salamanders have been protected under the Endangered Species Act for more than a decade, the Fish and Wildlife Service had not developed a required recovery plan to guide management of the species. In April 2012 the Center sued the Interior Department for its failure to develop such a plan for the endangered salamanders; the plan released today is the result of the December 2012 settlement agreement that resulted from this lawsuit.

Bitis Gabonica, commonly known as the Gabon viper, is a venomous viper species found in the rainforests and savannas of sub-Saharan Africa. It is not only the largest member of the genus bitis, but also the world’s heaviest viperid, and it has the longest fangs and the highest venom yield of any venomous snake.

Angolan scientist Paula Regina de Oliveira said the species of Bitis Gabonica are the ones with teeth that could reach five centimeters long and larger glands, which allow them to accumulate large amounts of venom.

"This horse has been beat so many times," said Eugene Bessette, commercial snake breeder and owner of Ophiological Services, a snake farm on Archer Road.

Even though Burmese pythons are not indigenous to South Florida, Bessette said he feels they are ultimately not an ecological problem.

"Ignorance is the biggest problem," Bessette said. “People form opinions before they get the facts."

Bessette lost a substantial part of his business when new regulations put in place in 2012 banned the importation and interstate transportation of Burmese pythons and three other constrictor snakes.

The aquarium was overseeing the rehabilitation of baby Loggerhead turtles found washed up along the Cape Coast predominantly in Struisbaai.

The family drove the turtle to the aquarium, where staff were on hand to meet them.

“Rosie was put into the rehabilitation tank along with the 178 other Loggerhead turtles currently in their care and by Sunday morning Two Oceans Aquarium staff confirmed that Rosie was doing well and appearing to be strong and healthy much to the delight of the Campbells,” Lambinon said.

He said of all the 179 Loggerheads found along the Cape coast to date, Rosie was the found the furthest south.
