A new report published in the journal Nature on Wednesday (April 27) has revealed that at least one in five reptile species at risk of extinction.

The first major global assessment of the world's so-called cold-blooded creatures has been evaluated them using criteria from the International Union for Conservation of Nature (IUCN) Red List of threatened species.

From the Galapagos tortoises to the Komodo dragon of the Indonesian islands, the study has been conducted on 10,196 reptile species including turtles, crocodilians, lizards, snakes, and the tuatara.

According to Neil Cox, who manages of the IUCN-Conservation International Biodiversity Assessment Unit and co-led the study, "It's just overwhelming the number of species that we see as being threatened."&nbsp;

"Now we know the threats facing each reptile species, the global community can take the next step by joining conservation plans with global policy agreement and invest in turning around the often too under-appreciated and severe biodiversity crisis." &nbsp;

"Global collaboration and commitment are a must if we are to prevent an extinction catastrophe," he added.

The biggest threat to reptiles are deforestation for agriculture, logging, and development, urban encroachment, and hunting by people.

Climate change has triggered catastrophic declines in biodiversity across the world with 31 species being identified as already extinct.

Not just this, 40 percent of amphibians, 25 percent of mammals, and 13 percent of birds are being pushed to the brink and could face extinction. &nbsp;

"Reptiles represent an important and diverse branch of the tree of life and play integral roles in the ecosystems where they occur," said Bruce Young, co-leader of the study.

"This global assessment is a key beginning to understanding reptile conservation needs. Now we know where the priorities are and what the threats are that we need to ameliorate. There is no longer any excuse for leaving reptiles out of conservation planning and implementation efforts worldwide," added Young.

One of the reptiles listed in the category of "least concern" about extinction includes Australia's saltwater crocodile. Meanwhile, Chapman's pygmy chameleon is among the most seriously threatened reptiles.

Hoping the new assessment will help spur international action to halt biodiversity loss, they stressed that the study highlights the need for specific urgent conservation for some reptiles. &nbsp;

At least one in five reptile species at risk of extinction: Report

As kids, all of us have learnt that smaller reptiles, such as lizards, can regrow&nbsp;their tails within days. However, researchers have recently discovered that&nbsp;alligators, too, have this lifesaving skill.

In a recent observation, researchers discovered that&nbsp;juvenile alligators have the ability to regrow their tails&nbsp;up to 9 inches, or up to 18 per cent of their total body length. this observation was made by a team of scientists from&nbsp;Arizona State University and the Louisiana Department of Wildlife and Fisheries. The study was published in 'Scientific Reports' with the title:&nbsp;Anatomical and histological analyses reveal that tail repair is coupled with regrowth in wild-caught, juvenile American alligators (Alligator mississippiensis).

"Using anatomical and histological data, we carried out a comparative analysis of the original and regrown tail segment tissues located near the junction site in the American alligator. All samples analyzed were obtained from wild-caught, juvenile or sub-adult alligators of both sexes (2F:1M) and were assigned a body condition score of 3, as all individuals were well-nourished and in good physical condition at the time of capture," the report read.

The scientists used&nbsp;advanced imaging techniques, with the tried and tested methods of studying&nbsp;anatomy and tissue organisation. As per the study, the regrown tail of the alligator has&nbsp;central cartilage skeleton without any bone which allows the tail to regenerate and heal the wounds on its own.

"The regrown skeleton was surrounded by connective tissue and skin but lacked any skeletal muscle (which lizard tails do regenerate with)," Kenro Kusumi, co-senior study author and professor and director of ASU's School of Life Sciences and associate dean in the College of Liberal Arts and Sciences, told CNN.

This study, experts believe,&nbsp;will help in the advancement of the regenerative therapies in human beings. "We know that humans -- who are incapable of regenerating -- have the same cells and pathways being used to regenerate in these other animals," Jeanne Wilson-Rawls, co-senior study author and associate professor with ASU's School of Life Sciences said. "If this very large long-limbed animal has this ability, can we take advantage of this to help people who have lost limbs or burn victims who need skin regeneration?"

Like lizards, alligators can regrow their tails too: Study

A distant relative of the Tyrannosaurus Rex has been discovered in the plains of Patagonia, Argentina – albeit much smaller than the ferocious monster we’ve come to know from the big screen.
