A Biological Reviews study analyzing hundreds of reports across 207 snake species finds that cannibalism is widespread and has evolved at least 11 times, indicating it’s an adaptive survival strategy in response to ecological stress and food scarcity—occurring in both the wild and captivity to regulate populations and boost ecological fitness; some experts caution against broad generalizations across all species.
A review of 503 cannibalism reports across 207 snake species finds cannibalistic behavior has evolved independently at least 11 times, in both wild and captive settings. Cannibalism occurs across diverse contexts and is often tied to environmental stress or opportunistic feeding. Jaw structure enabling swallowing other snakes, along with dietary flexibility in some species, may help explain the pattern. The study suggests cannibalism is more common in snakes than previously thought and may be an adaptive response to scarce resources.
A review of 503 cannibalism reports across 207 snake species finds that cannibalistic behavior has evolved independently at least 11 times. The behavior appears across continents and contexts, often linked to environmental stress or scarce food, with many captivity cases; jaw flexibility and dietary generalism help some snakes consume conspecifics. Researchers say cannibalism can provide ecological fitness as an opportunistic feeding strategy, though much of the data are anecdotal and more study is needed.
Scientists observed snakes dragging toxin-containing frogs across the ground before eating them, revealing how some animals have evolved mechanisms like toxin degradation or resistance to survive and even co-opt deadly chemicals, highlighting the complex chemical arms race in nature.
The article describes the presence of non-venomous fox snakes in the Upper Peninsula, highlighting a recent mating encounter observed by the author, and emphasizes the ecological benefits of snakes as natural rodent control, along with a reminder to be cautious of turtles during egg-laying season.
Scientists have found that snakes possess a unique ability to evolve at an accelerated rate compared to other reptiles, allowing them to diversify and spread across the world. A recent study revealed that snakes evolved three times faster than lizards, with their rapid evolution continuing to this day. This flexibility enables them to quickly adapt their body shape and diets, leading to their success as an evolutionary "winner." However, the reason behind snakes' fast evolutionary clock remains a mystery, leaving scientists with new questions to answer.
A rare achievement in Assassin's Creed Mirage, called Eagle's Will, which requires players to survive for ten minutes in open conflict, is actually easy to unlock by sitting on a wall near a snake for the duration. This method has been successful for many players and eliminates the need for intense combat skills.
The Golder Ranch Fire Department removed a total of 11 snakes, including 9 baby rattlesnakes, from a home in Oro Valley, Arizona. As the weather becomes slightly cooler and more humid, there is an increased likelihood of encountering snakes. If you come across a snake, it is important to stay calm, step out of striking range, and walk away without agitating the snake. If snakes are found on your property, call 911 for assistance with removal.
Guests at the Country Inn and Suites by Radisson in Germantown, Wisconsin, were shocked to find snakes in the pool, hot tub, hallway, and even a guest room. The snakes, believed to be northern water snakes, were likely from the wetlands behind the hotel. While some guests took matters into their own hands to remove the snakes, the hotel refused full refunds and blamed a guest for the incident. Choice Hotels, which owns Radisson, declined to comment. The hotel claims it has taken steps to prevent similar incidents in the future.
Unusually high temperatures in Australia have caused snake season to start early, with the Australian Reptile Park issuing an "urgent warning" for people to be on the lookout for venomous snakes. The rise in temperatures and winter rainfall has created the perfect environment for snakes to become more active. Snake catchers have reported a significant increase in callouts, a phenomenon rarely seen at this time of year. As global temperatures continue to rise, Australia's winters have been steadily warming. In the UK, rising temperatures are also affecting the snake population, with more pet snakes breaking free from their enclosures due to the warming climate.
A non-venomous black whip snake in Israel died after attempting to eat a porcupine, with both animals meeting their demise in the encounter. The snake's failed attempt was due to the one-way direction of the porcupine's quills, preventing it from spitting out the porcupine. Snakes, including the black whip snake, play an important role in maintaining the ecosystem by controlling the rodent population. Both snakes and porcupines are protected animals in Israel, and any encounters with distressed animals should be reported to the Parks and Nature authority.
As the highly anticipated Indiana Jones and the Dial of Destiny hits theaters, some shocking behind-the-scenes facts about the previous movies have emerged. For instance, 7,000 real snakes were used for the iconic Well of Souls scene in Raiders of the Lost Ark, and many people, including snake handlers and actors, were bitten during filming. In Temple of Doom, approximately 30,000 beetles and 50,000 cockroaches were gathered for a skin-crawling scene, and actor Kate Capshaw had to endure buckets of insects being poured onto her. Additionally, 2,000 rats were specially bred for the water-filled catacombs scene in Indiana Jones and the Last Crusade.
A comprehensive genome survey has identified the genes, regulatory elements, and structural variations that have contributed to evolutionary changes in snakes, including the loss of limbs. Researchers hope that these discoveries will boost knowledge of biological development and aid in the development of antivenom drugs.
Scientists have used CRISPR gene-editing to create the world's first genetically modified snakes, which lack the hexagonal scales found on the dorsal-lateral scales of corn snakes. The researchers found that the spatial organisation of the placodes that determine the positioning of the scales follows a pattern first explained by mathematician Alan Turing. The study provides new insight into how snakes develop their precisely patterned scales, which are the result of placodes, small, thickened structures on the skin that develop at the embryonic level.
NASA has announced the four astronauts who will lead the first crewed moon mission in over 50 years, including the first woman and person of color to be assigned to a lunar mission. Scientists have discovered that long-term memories take root in an area of the brain that hasn't typically been associated with memory processing, which could help researchers studying Alzheimer's disease. Astronomers are excited by the discovery of a rocky Earth-size exoplanet with a magnetic field, which could potentially support life. Researchers have recorded the dwarf reed snake, which deploys a gravity-defying cartwheel when threatened by predators, a behavior not formally observed in any other species of snake or reptile.
