The royal came face to face with a Tuatara lizard, also named Harry, during a welcome ceremony in the city of Invercargill.

The Prince came up close and personal with the 100-year-old reptile as it settled on his arm.

The Tuatara is only found in New Zealand where it is revered in native Maori culture as a messenger of the gods.

It was back to business as usual afterwards as Prince Harry then faced a crowd of screaming female fans - one of whom even managed to plant a kiss on the Royal.

The Arizona Poison and Drug Information Center at the University of Arizona College of Pharmacy in Tucson and the Banner Poison and Drug Information Center at Banner-University Medical Center in Phoenix will be conducting a study to find the most effective way to use the two antivenoms.

"Arizona has the largest diversity of rattlesnake bites in the country and what we see in all these rattlesnake bites is an incredible diversity of patients and the kind of effects we see in the rattlesnakes themselves," said Keith Boesen, director of the Arizona Poison and Drug Information Center.

Every year, there are between 250 to 350 rattlesnake bites in Arizona. Many of the victims credit antivenom for saving their lives.

The Everglades alligators appear to be suffering from the artificial water management imposed on the area to drain land for cities and farms, he said.

Before the canals and pumps and other structures went up over the past century, he said there were sufficient dry periods to concentrate prey, allowing the alligators to find enough food. But now, some areas are flooded year-round, allowing fish, turtles and other prey to spread out over a wide area. That makes it harder for the alligators to find enough to eat.

"They are thinner," he said. "They're not getting enough to eat. We've been seeing that for a number of years, specifically in the Everglades and the water conservation areas.'

The Lake Oku clawed frog is native to only Lake Oku in Cameroon and, due to their unique history of evolution (including the loss of their tongues), the aquatic frogs are tottering on the brink of extinction.

A team of amphibian keepers at the zoo are the first to ever successfully breed the frog, sparking fresh hope of ensuring the survival of the species.

Zookeepers have been intent on maintaining perfect conditions for the amphibians to thrive and four of the zoo’s 13 tadpoles have already metamorphosed into young, colourful frogs.

Kelly Sloan, sea turtle program coordinator Sanibel/Captiva Conservation Foundation, also has plans to make this a good year for turtles.

"Coyotes are a problem," Sloan explained. "We are going to attempt to screen every nest this year. Hopefully that will keep the coyotes out."

Sloan is also hoping for lots of green turtles this year. They had a record number of greens, 23 of them, in 2013 and none last year. Sloan is also starting a big campaign with a slogan "After Nine it's Turtle Time," in an attempt to get people to turn off or conceal lights at night. Hatchlings use the lights from the horizon to find the water. Artificial light can lure them the wrong way.

And when it comes to mating, this family of frogs has a unique trait not seen in other frogs.

They typically like to live near fast streams and, if a pair decides to mate, they will spend five minutes searching for a private spot.

‘The male quickly carves out a chamber by excavating the sand around small rocks at the bottom of the stream,’ said Agata Blaszczak-Boxe from New Scientist.

‘Then, like Christian Grey from Fifty Shades he invites his mate into his sex dungeon, which is only just big enough to fit the two amorous amphibians.’

Lang Tengah Turtle Watch co-founder Raphe van Zevenbergen said he noticed clumps of tar balls washing up ashore along the 15m-stretch beach and immediately lodged a report with the marine park authorities.

“So far, we have collected some 13 bags of tar balls. We are concerned that the tar might seep into the sand. We have also asked for help from the nearby resorts.

“They have been very obliging in cleaning their own sections of the beach as we all await assistance from the authorities,” he said.

Lang Tengah Island, which is just under three kilometres in length, is popularly known as Turtle Bay due to its known turtle nesting population, predominantly the green turtles.
