The last-ditch race to save the Orinoco crocodile
CAPANAPARO, Venezuela (Reuters) -Venezuelan biologist Carlos Alvarado, 34, has one hand on the young crocodile's neck and another on its tail. With the help of some tape and calipers, he is measuring it, tracking its growth a few days before it will be released into the wild.
Alvarado's story - and that of the Orinoco crocodile he is caring for - is a tale of hope and persistence in the face of overwhelming odds.
Fewer than 100 Orinoco crocodiles - one of the largest living reptiles in the world - remain in the wild, according to Venezuelan conservation foundation FUDECI. The animal's natural habitat is in the Orinoco River basin, which covers most of Venezuela and spills into Colombia.
For decades, the men and women of the Venezuelan Crocodile Specialist Group have been raising younglings of the critically endangered species in captivity in a race against time to avoid its extinction.
But they say they are losing that race. Decades of poaching for leather pushed the Orinoco crocodile to the brink, and now struggling Venezuelans who hunt the animals for meat and take their eggs for food threaten to deal the final blow. The members of the Crocodile Specialist Group are not getting any younger - and the next generation of biologists has mostly fled turmoil in Venezuela for jobs elsewhere.
Alvarado remains alone to take up the baton. It is, he says, "a great responsibility." He has a sense of mission. He is trying to persuade university students to take part in the conservation effort.
Federico Pantin, 59, is not optimistic. He is director of the Leslie Pantin Zoo in Turmero, near Caracas, which specializes in endangered species and is one of the places where the crocodile hatchlings are raised.
"We're only delaying the Orinoco's extinction," he says.
Pantin and his colleagues keep on going, however - researching, measuring, transporting.
The scientists log the sites where the long-snouted Orinoco are known to nest, collecting their eggs or hatchlings. They also breed captive adults kept at the zoo and at Masaguaral Ranch, a biodiversity center and cattle farm near Tamarindito in central Venezuela.
The scientists raise the babies, feeding them a diet of chicken, beef and vitamins until they are about a year old and grow to a weight of around 6 kg (13 lb).
Adult Orinocos can reach over 5 meters (16 ft) in length, and can live for decades - a 70-year-old named Picopando resides at Masaguaral Ranch. The adults have tough, bony armor, fierce jaws and sharp teeth. They are not to be trifled with.
But when they are first hatched, a researcher can cradle one in their hands.
Omar Hernandez, 63, biologist and head of FUDECI, tags the tiny foot of a hatchling at the Leslie Pantin Zoo. To save the species, a number of efforts would be necessary, he says: research, protection, education, and management.
"We are doing the management, collecting the hatchlings, raising them for a year and freeing them," he says. But "that is practically the only thing being done. And it is not being done at scale."
Every year the group releases around 200 young crocs into the wild.
The biologists wait until they are a year old as that is the most critical period in their life, Hernandez says. It is when they are young that "almost all are hunted."
In April, Reuters accompanied the scientists as they released this year's batch. The young animals were placed in crates, their jaws bound, for the journey from the zoo to the Capanaparo River, deep in western Venezuela not far from the Colombian border, where human habitations are few and far between. This part of the river passes through private land, reducing the likelihood that the animals will immediately be hunted.
Alvaro Velasco, 66, who has a tattoo of an Orinoco crocodile on his right shoulder, covered the eyes of a juvenile with tape to avoid it becoming stressed during the journey.
"People ask me, 'Why crocodiles? They're ugly,'" said Velasco, president of the Crocodile Specialist Group. "To me, they're fabulous animals. You release them and they stay there, looking at you, as if to say 'What am I supposed to do in this huge river?' And then they swim off."
Pickup trucks drove the scientists, crocodiles and volunteers along muddy tracks to a camp near the river, where the humans spent the night sleeping in hammocks.
The next day, they gently removed the crocodiles from their crates and carried them to the river.
The juveniles slid into the muddy, greenish waters.
"Maybe many of these animals are going to be killed tomorrow or the day after tomorrow because of a lack of awareness among people and of course because of hunger," said Hernandez. He echoed Pantin's comments that ultimately the Orinoco crocodile was likely doomed.
But, he said, "we're stubborn. It's a way of delaying extinction and it's something that is in our capacity to do. If we waited for the perfect circumstances, they would never come."

Meet the 'Python Huntress', who has more than 600 dead pythons under her belt
Siewe is a professional hunter of the invasive Burmese python in Florida. — Photos: Reuters Amy Siewe was a successful real estate agent – but her life changed after she captured her first python in Florida's Everglades in the United States. 'I just had this fascination with snakes. So when I learned that there was a python problem here in Florida... I went on a hunt, I caught a 2.75m python, and that was it. I was hooked!' she said. Within two months she had sold her business in Indiana and moved to Florida to become a python hunter. Now, with more than 600 dead pythons under her belt, she is known as the 'Python Huntress' – one of a handful of women among hundreds of men hunting the invasive Burmese python in Florida's Everglades wetland ecosystem. 'This python is about 3m long,' she says as she wrestles a snake she has just captured in the tall grass in the middle of the night. 'It's probably about three years old, and to date it's eaten about 200 of our native animals, including mammals and birds.' The snakeskins are tanned into leather and dyed, then turned into fashion accessories and other goods. Burmese pythons have been spreading through the Everglades National Park since Hurricane Andrew in 1992 destroyed a breeding facility for the pet trade, freeing some 900 snakes. Originally native to South-East Asia, the python can grow up to 5.5m long and has a voracious appetite, consuming the local wildlife, including mammals, birds and even alligators. The Everglades is a unique subtropical ecosystem, with the largest continuous mangrove ecosystem in the Western Hemisphere. It is home to a vast array of unique species, including the endangered Florida panther, the American alligator and the American crocodile. But it provides no natural predators to the Burmese python, allowing the population of the invasive species to balloon. Scientists have noted dramatic declines in raccoons, opossums, bobcats, and rabbits in the region. 'There's an estimated 500,000 pythons out there,' Siewe said. Siewe and her boyfriend Dave Roberts measuring a python they caught in Ochopee, Florida. The pythons, which are hunted by night, cannot legally be transported alive, so they are killed on site after being captured and measured. Once home, Siewe skins the dead snakes, and then has the skins professionally tanned into leather to be made into purses, wallets, watch bands and other goods. It takes an average of 12 hours to catch one. 'So it's not that effective, right,' she admits. 'We're always going to have pythons in Florida. What we're trying to do is figure out how to decrease their numbers. Hunting right now is the most effective tool that we have.' – Reuters

Indian canteen worker's hopes dashed, no second miracle in air crash
FILE PHOTO: A fire officer stands next to the crashed Air India Boeing 787-8 Dreamliner aircraft, in Ahmedabad, India, June 13, 2025. - Photo: Reuters AHMEDABAD, (India): Ravi Thakor had been hoping his mother and two-year old daughter had escaped just before an Air India jet crashed into the building they were in. A week after one of the world's worst aviation disasters killed more than 270 people in the western Indian city of Ahmedabad, Thakor's hopes were dashed when doctors matched his DNA on Wednesday (June 18) with the remains of his mother Sarla and daughter Aadhya. A canteen worker in a college hostel, Thakor and other family members had left the hostel around 30 minutes before Air India's Boeing 787 Dreamliner aircraft crashed into the building. Sarla had stayed back, cooking and looking after Aadhya, who was asleep. Thakor and his wife Lalita searched for them in hospitals and the morgue after the crash. After not finding them for days, they said they were hoping for a "second miracle", referring to the lone passenger aboard the plane who survived the disaster. On Thursday, the dead bodies were handed over to Thakor's family for the final rites. "We are going to cremate my mother and daughter. It is very difficult for me to say anything right now, but at least we know what happened to them," Thakor said, struggling to speak. At least 211 DNA samples had been matched, and 189 dead bodies handed over to families, Rakesh Joshi, the medical superintendent at the Ahmedabad Civil Hospital told reporters on Thursday. The dead included 241 people on board the plane and at least 30 on the ground. - Reuters

More than 200 India plane crash victims identified
People carry the coffin containing the body of Akash Patni, who died after an Air India Boeing 787-8 Dreamliner plane crashed during take-off from an airport, in Ahmedabad, Gujarat on June 17, 2025. - Photo: Reuters AHMEDABAD, (India): More than 200 victims of the Air India jet crash have been identified through DNA testing, Indian authorities said Wednesday (June 18), inching towards ending an agonising wait for relatives. There was one survivor out of 242 passengers and crew on board the London-bound plane on Thursday when it slammed into a residential area of Ahmedabad, killing at least 38 people on the ground. Distraught relatives have been providing DNA samples to help identify their loved ones, in a painstakingly slow process. "As of 2 pm, 202 DNA (samples) have been matched," Harsh Sanghavi, home minister of Ahmedabad's Gujarat state, wrote on X. The Boeing 787-8 Dreamliner erupted into a fireball when it crashed moments after takeoff, with witnesses reporting seeing badly burnt bodies and scattered remains. Indian authorities are yet to announce the cause of the crash and investigators from Britain and the United States have joined the probe. Investigators are aiming to retrieve vital information from both black boxes recovered from the site -- the cockpit voice recorder and the flight data recorder. India's Aircraft Accident Investigation Bureau upgraded a laboratory this year where black boxes can be analysed. Following the crash, the civil aviation regulator ordered inspections of Air India's Dreamliners. Initial checks on the fleet "did not reveal any major safety concerns", the regulator said late Tuesday. "The aircraft and associated maintenance systems were found to be compliant with existing safety standards," it said. - AFP
