Massive floods across Zimbabwe, Mozambique and South Africa have killed more than 100 people and displaced about 400,000, with crocodiles washed into towns; Mozambique’s floods are among the worst since 2000, farmland and livestock losses mount, cholera and other waterborne diseases threaten camps, and funding for relief and infrastructure repair remains slow.
An American influencer, Mike Holston, is under investigation in Queensland, Australia, for filming himself wrestling wild crocodiles, an activity deemed extremely dangerous and illegal, prompting outrage and potential fines from authorities.
Bob Irwin condemns reckless social media influencers like Mike Holston for dangerous crocodile interactions, calling for stricter enforcement of wildlife laws and potential deportation, amid ongoing investigations and concerns over wildlife safety and legal compliance in Australia.
Israel culled 200 crocodiles from an abandoned farm in the West Bank due to cannibalism and safety concerns, citing poor conditions and escape risks, amid controversy over animal rights and management practices.
A study by researchers at the University of Geneva has uncovered that the irregular head scales of crocodiles are formed through compressive mechanical instabilities rather than tensile stress. This process occurs during embryonic development, where the skin grows faster than the bone beneath it, leading to the formation of polygonal scales. The findings, published in Nature, suggest that variations in head-scale patterns among crocodilians may be due to evolutionary differences in embryonic skin growth.
Researchers have discovered that the irregular scales on crocodile heads form through a mechanical process rather than genetic control. Unlike typical scale formation, which is gene-driven, the scales on crocodile heads arise because the skin grows faster than the underlying tissues, causing it to fold and create irregular patterns. This finding, published in Nature, was supported by experiments with Nile crocodile embryos and computer simulations, highlighting the role of skin growth rate and material properties in scale patterning.
Crocodilians, including crocodiles, gharials, alligators, and caimans, have survived for over 200 million years due to a combination of anatomical and behavioral adaptations. Their almost impenetrable body armor, powerful antioxidants in their blood, and ability to remain still for long periods contribute to their resilience. These survival tactics have drawn the attention of researchers for potential applications in treating human diseases, showcasing how nature's resilience can inform and transform our approach to health challenges.
Desperate Australians in flood-ravaged areas are risking their lives by wading through crocodile-infested waters to escape their damaged homes or reach higher ground. Some towns remain isolated, with dwindling supplies and power. Evacuation efforts have been hindered by dangerous weather conditions, but authorities have managed to rescue some residents, prioritizing the elderly and vulnerable. The flooding, caused by Tropical Cyclone Jasper, has caused extensive damage to properties, roads, and farms. The recovery effort is expected to be costly, and there are concerns about potential insurance claims.
Researchers at the University of York have mapped the family tree of crocodiles and their extinct relatives, shedding light on their evolution. The study found that climate change and competition with other species have influenced the diversity of modern-day crocodiles and their extinct relatives. The research also revealed that ecology, such as living in the sea, freshwater, or on land, played a significant role in their survival. The findings provide important insights for conservation efforts as crocodile species face threats from rising sea levels and climate change.
Researchers have uncovered the complex evolutionary history of crocodiles, revealing that the larger group of crocodilians likely originated in Europe and then spread around the world. The ancestors of crocodiles and alligators split in North America, with crocodiles' ability to tolerate saltwater allowing them to colonize various regions. The study also found that crocodiles' slow growth rate is a secondary adaptation not found in their distant relatives. The research highlights the diverse lifestyles and adaptations of ancient crocodilians, including herbivorous species and marine predators.
Three crocodiles in Maharashtra, India, displayed an unexpected act of empathy when they encountered a young dog being chased by feral dogs. Instead of attacking the dog, the crocodiles nudged it towards safety, guiding it away from danger. Scientists studying the crocodiles believe that this behavior demonstrates emotional empathy and challenges the perception of reptile cognition. Additionally, the researchers discovered that the crocodiles showed a fondness for marigold flowers, possibly due to their antimicrobial properties. The incident highlights the complex behavior and emotional intelligence of crocodiles.
Crocodiles were observed seemingly escorting a stray dog to safety instead of attacking it, leaving scientists puzzled. The crocs, within striking range, exhibited docile behavior and nudged the dog away from potential harm. Researchers suggest that this unexpected behavior may indicate a higher cognitive function and emotional empathy in crocodiles.
Scientists in India have observed mugger crocodiles engaging in unusual behaviors, including hunting in packs, using sticks as bait, showing interest in flower garlands, and even saving a feral dog from other dogs. While these observations suggest that mugger crocodiles may be more cognitively advanced than previously believed, some experts remain skeptical, cautioning against anthropomorphizing their behaviors. The study provides anecdotal evidence of these behaviors, but more rigorous research is needed to draw definitive conclusions.
Heavy floods in southern China caused dozens of crocodiles to escape from a commercial crocodile farm in Maoming, Guangdong province. Authorities confirmed that 69 adult crocodiles and six juveniles were on the loose in the flooded area. Videos circulating on social media showed crocodiles swimming in floodwaters, prompting warnings for residents to stay home. Some crocodiles have been recaptured, but no injuries have been reported. Crocodile meat is highly valued in China, and while the trade is not prohibited, there are illegal farms in the country. This is not the first time crocodiles have escaped from farms in the area due to flooding.
More than 70 crocodiles escaped from a commercial farm in Maoming, Guangdong, after heavy flooding caused a local lake to overflow. Authorities launched a rescue operation to recapture the reptiles, with some residents warned to stay indoors. The depth of the floodwater posed a challenge to the operation, and authorities may have to euthanize the crocodiles. Crocodile farming is popular in Guangdong due to its warmer climate.
